-/**
- * @fileoverview An event manager for both native browser event
- * targets and custom JavaScript event targets
- * ({@code goog.events.Listenable}). This provides an abstraction
- * over browsers' event systems.
- *
- * It also provides a simulation of W3C event model's capture phase in
- * Internet Explorer (IE 8 and below). Caveat: the simulation does not
- * interact well with listeners registered directly on the elements
- * (bypassing goog.events) or even with listeners registered via
- * goog.events in a separate JS binary. In these cases, we provide
- * no ordering guarantees.
- *
- * The listeners will receive a "patched" event object. Such event object
- * contains normalized values for certain event properties that differs in
- * different browsers.
- *
- * Example usage:
- * <pre>
- * goog.events.listen(myNode, 'click', function(e) { alert('woo') });
- * goog.events.listen(myNode, 'mouseover', mouseHandler, true);
- * goog.events.unlisten(myNode, 'mouseover', mouseHandler, true);
- * goog.events.removeAll(myNode);
- * </pre>
- *
- * in IE and event object patching]

-
-// IMPLEMENTATION NOTES:
-// goog.events stores an auxiliary data structure on each EventTarget
-// source being listened on. This allows us to take advantage of GC,
-// having the data structure GC'd when the EventTarget is GC'd. This
-// GC behavior is equivalent to using W3C DOM Events directly.

- * @classdesc

- * Most non-trivial classes inherit from this.
- *
- * This extends {@link ol.Observable} with observable properties, where each
- * property is observable as well as the object as a whole.
- *
- * Classes that inherit from this have pre-defined properties, to which you can
- * add your owns. The pre-defined properties are listed in this documentation as
- * 'Observable Properties', and have their own accessors; for example,
- * {@link ol.Map} has a `target` property, accessed with `getTarget()` and
- * changed with `setTarget()`. Not all properties are however settable. There
- * are also general-purpose accessors `get()` and `set()`. For example,
- * `get('target')` is equivalent to `getTarget()`.
- *
- * The `set` accessors trigger a change event, and you can monitor this by
- * registering a listener. For example, {@link ol.View} has a `center`
- * property, so `view.on('change:center', function(evt) {...});` would call the
- * function whenever the value of the center property changes. Within the
- * function, `evt.target` would be the view, so `evt.target.getCenter()` would
- * return the new center.
- *
- * You can add your own observable properties with
- * `object.set('prop', 'value')`, and retrieve that with `object.get('prop')`.
- * You can listen for changes on that property value with
- * `object.on('change:prop', listener)`. You can get a list of all
- * properties with {@link ol.Object#getProperties object.getProperties()}.
- *
- * Note that the observable properties are separate from standard JS properties.
- * You can, for example, give your map object a title with
- * `map.title='New title'` and with `map.set('title', 'Another title')`. The
- * first will be a `hasOwnProperty`; the second will appear in
- * `getProperties()`. Only the second is observable.
- *
- * Properties can be deleted by using the unset method. E.g.
- * object.unset('foo').

/**
* @classdesc
- * Projection definition class. One of these is created for each projection
- * supported in the application and stored in the {@link ol.proj} namespace.
- * You can use these in applications, but this is not required, as API params
- * and options use {@link ol.proj.ProjectionLike} which means the simple string
- * code will suffice.
+ * An ol.View object represents a simple 2D view of the map.
*
- * You can use {@link ol.proj.get} to retrieve the object for a particular
- * projection.
+ * This is the object to act upon to change the center, resolution,
+ * and rotation of the map.
*
- * The library includes definitions for `EPSG:4326` and `EPSG:3857`, together
- * with the following aliases:
- * * `EPSG:4326`: CRS:84, urn:ogc:def:crs:EPSG:6.6:4326,
- * urn:ogc:def:crs:OGC:1.3:CRS84, urn:ogc:def:crs:OGC:2:84,
- * http://www.opengis.net/gml/srs/epsg.xml#4326,
- * urn:x-ogc:def:crs:EPSG:4326
- * * `EPSG:3857`: EPSG:102100, EPSG:102113, EPSG:900913,
- * urn:ogc:def:crs:EPSG:6.18:3:3857,
- * http://www.opengis.net/gml/srs/epsg.xml#3857
+ * ### The view states
*
- * If you use proj4js, aliases can be added using `proj4.defs()`; see
- * [documentation](https://github.com/proj4js/proj4js).
+ * An `ol.View` is determined by three states: `center`, `resolution`,
+ * and `rotation`. Each state has a corresponding getter and setter, e.g.
+ * `getCenter` and `setCenter` for the `center` state.
+ *
+ * An `ol.View` has a `projection`. The projection determines the
+ * coordinate system of the center, and its units determine the units of the
+ * resolution (projection units per pixel). The default projection is
+ * Spherical Mercator (EPSG:3857).
+ *
+ * ### The constraints
+ *
+ * `setCenter`, `setResolution` and `setRotation` can be used to change the
+ * states of the view. Any value can be passed to the setters. And the value
+ * that is passed to a setter will effectively be the value set in the view,
+ * and returned by the corresponding getter.
+ *
+ * But an `ol.View` object also has a *resolution constraint*, a
+ * *rotation constraint* and a *center constraint*.
+ *
+ * As said above, no constraints are applied when the setters are used to set
+ * new states for the view. Applying constraints is done explicitly through
+ * the use of the `constrain*` functions (`constrainResolution` and
+ * `constrainRotation` and `constrainCenter`).
+ *
+ * The main users of the constraints are the interactions and the
+ * controls. For example, double-clicking on the map changes the view to
+ * the "next" resolution. And releasing the fingers after pinch-zooming
+ * snaps to the closest resolution (with an animation).
+ *
+ * The *resolution constraint* snaps to specific resolutions. It is
+ * determined by the following options: `resolutions`, `maxResolution`,
+ * `maxZoom`, and `zoomFactor`. If `resolutions` is set, the other three
+ * options are ignored. See documentation for each option for more
+ * information.
+ *
+ * The *rotation constraint* snaps to specific angles. It is determined
+ * by the following options: `enableRotation` and `constrainRotation`.
+ * By default the rotation value is snapped to zero when approaching the
+ * horizontal.
+ *
+ * The *center constraint* is determined by the `extent` option. By
+ * default the center is not constrained at all.

/**
- * @classdesc
- * An ol.View object represents a simple 2D view of the map.
- *
- * This is the object to act upon to change the center, resolution,
- * and rotation of the map.
- *
- * ### The view states
- *
- * An `ol.View` is determined by three states: `center`, `resolution`,
- * and `rotation`. Each state has a corresponding getter and setter, e.g.
- * `getCenter` and `setCenter` for the `center` state.
- *
- * An `ol.View` has a `projection`. The projection determines the
- * coordinate system of the center, and its units determine the units of the
- * resolution (projection units per pixel). The default projection is
- * Spherical Mercator (EPSG:3857).
- *
- * ### The constraints
- *
- * `setCenter`, `setResolution` and `setRotation` can be used to change the
- * states of the view. Any value can be passed to the setters. And the value
- * that is passed to a setter will effectively be the value set in the view,
- * and returned by the corresponding getter.
- *
- * But an `ol.View` object also has a *resolution constraint*, a
- * *rotation constraint* and a *center constraint*.
- *
- * As said above, no constraints are applied when the setters are used to set
- * new states for the view. Applying constraints is done explicitly through
- * the use of the `constrain*` functions (`constrainResolution` and
- * `constrainRotation` and `constrainCenter`).
- *
- * The main users of the constraints are the interactions and the
- * controls. For example, double-clicking on the map changes the view to
- * the "next" resolution. And releasing the fingers after pinch-zooming
- * snaps to the closest resolution (with an animation).
- *
- * The *resolution constraint* snaps to specific resolutions. It is
- * determined by the following options: `resolutions`, `maxResolution`,
- * `maxZoom`, and `zoomFactor`. If `resolutions` is set, the other three
- * options are ignored. See documentation for each option for more
- * information.
- *
- * The *rotation constraint* snaps to specific angles. It is determined
- * by the following options: `enableRotation` and `constrainRotation`.
- * By default the rotation value is snapped to zero when approaching the
- * horizontal.
- *
- * The *center constraint* is determined by the `extent` option. By
- * default the center is not constrained at all.

- * can be obtained via constructor invocation.
- *
- * A SafeStyle's string representation ({@link #getTypedStringValue()}) can
- * safely:
- * <ul>
- * <li>Be interpolated as the entire content of a *quoted* HTML style
- * attribute, or before already existing properties. The SafeStyle string
- * *must be HTML-attribute-escaped* (where " and ' are escaped) before
- * interpolation.
- * <li>Be interpolated as the entire content of a {}-wrapped block within a
- * stylesheet, or before already existing properties. The SafeStyle string
- * should not be escaped before interpolation. SafeStyle's contract also
- * guarantees that the string will not be able to introduce new properties
- * or elide existing ones.
- * <li>Be assigned to the style property of a DOM node. The SafeStyle string
- * should not be escaped before being assigned to the property.
- * </ul>
- *
- * A SafeStyle may never contain literal angle brackets. Otherwise, it could
- * be unsafe to place a SafeStyle into a <style> tag (where it can't
- * be HTML escaped). For example, if the SafeStyle containing
- * "{@code font: 'foo <style/><script>evil</script>'}" were
- * interpolated within a <style> tag, this would then break out of the
- * style context into HTML.
- *
- * A SafeStyle may contain literal single or double quotes, and as such the
- * entire style string must be escaped when used in a style attribute (if
- * this were not the case, the string could contain a matching quote that
- * would escape from the style attribute).
- *
- * Values of this type must be composable, i.e. for any two values
- * {@code style1} and {@code style2} of this type,
- * {@code goog.html.SafeStyle.unwrap(style1) +
- * goog.html.SafeStyle.unwrap(style2)} must itself be a value that satisfies
- * the SafeStyle type constraint. This requirement implies that for any value
- * {@code style} of this type, {@code goog.html.SafeStyle.unwrap(style)} must
- * not end in a "property value" or "property name" context. For example,
- * a value of {@code background:url("} or {@code font-} would not satisfy the
- * SafeStyle contract. This is because concatenating such strings with a
- * second value that itself does not contain unsafe CSS can result in an
- * overall string that does. For example, if {@code javascript:evil())"} is
- * appended to {@code background:url("}, the resulting string may result in
- * the execution of a malicious script.
- *
- * TODO(user): Consider whether we should implement UTF-8 interchange
- * validity checks and blacklisting of newlines (including Unicode ones) and
- * other whitespace characters (\t, \f). Document here if so and also update
- * SafeStyle.fromConstant().
- *
- * The following example values comply with this type's contract:
- * <ul>
- * <li><pre>width: 1em;</pre>
- * <li><pre>height:1em;</pre>
- * <li><pre>width: 1em;height: 1em;</pre>
- * <li><pre>background:url('http://url');</pre>
- * </ul>
- * In addition, the empty string is safe for use in a CSS attribute.
- *
- * The following example values do NOT comply with this type's contract:
- * <ul>
- * <li><pre>background: red</pre> (missing a trailing semi-colon)
- * <li><pre>background:</pre> (missing a value and a trailing semi-colon)
- * <li><pre>1em</pre> (missing an attribute name, which provides context for
- * the value)

-/**
- * A string-like object which represents a CSS style sheet and that carries the
- * security type contract that its value, as a string, will not cause untrusted
- * script execution (XSS) when evaluated as CSS in a browser.
- *
- * Instances of this type must be created via the factory method
- * {@code goog.html.SafeStyleSheet.fromConstant} and not by invoking its
- * constructor. The constructor intentionally takes no parameters and the type
- * is immutable; hence only a default instance corresponding to the empty string
- * can be obtained via constructor invocation.
- *
- * A SafeStyleSheet's string representation can safely be interpolated as the
- * content of a style element within HTML. The SafeStyleSheet string should
- * not be escaped before interpolation.
- *
- * Values of this type must be composable, i.e. for any two values
- * {@code styleSheet1} and {@code styleSheet2} of this type,
- * {@code goog.html.SafeStyleSheet.unwrap(styleSheet1) +
- * goog.html.SafeStyleSheet.unwrap(styleSheet2)} must itself be a value that
- * satisfies the SafeStyleSheet type constraint. This requirement implies that
- * for any value {@code styleSheet} of this type,
- * {@code goog.html.SafeStyleSheet.unwrap(styleSheet1)} must end in
- * "beginning of rule" context.
- * A SafeStyleSheet can be constructed via security-reviewed unchecked
- * conversions. In this case producers of SafeStyleSheet must ensure themselves
- * that the SafeStyleSheet does not contain unsafe script. Note in particular
- * that {@code <} is dangerous, even when inside CSS strings, and so should
- * always be forbidden or CSS-escaped in user controlled input. For example, if
- * {@code </style><script>evil</script>"} were interpolated
- * inside a CSS string, it would break out of the context of the original
- * style element and {@code evil} would execute. Also note that within an HTML
- * style (raw text) element, HTML character references, such as
- * {@code &lt;}, are not allowed. See
- * http://www.w3.org/TR/html5/scripting-1.html#restrictions-for-contents-of-script-elements

- * A pattern that recognizes a commonly useful subset of URLs that satisfy
- * the SafeUrl contract.
- *
- * This regular expression matches a subset of URLs that will not cause script
- * execution if used in URL context within a HTML document. Specifically, this
- * regular expression matches if (comment from here on and regex copied from
- * Soy's EscapingConventions):
- * (1) Either a protocol in a whitelist (http, https, mailto or ftp).
- * (2) or no protocol. A protocol must be followed by a colon. The below
- * allows that by allowing colons only after one of the characters [/?#].
- * A colon after a hash (#) must be in the fragment.
- * Otherwise, a colon after a (?) must be in a query.
- * Otherwise, a colon after a single solidus (/) must be in a path.
- * Otherwise, a colon after a double solidus (//) must be in the authority
- * (before port).
- *
- * The pattern disallows &, used in HTML entity declarations before
- * one of the characters in [/?#]. This disallows HTML entities used in the
- * protocol name, which should never happen, e.g. "http" for "http".
- * It also disallows HTML entities in the first path part of a relative path,
- * e.g. "foo<bar/baz". Our existing escaping functions should not produce
- * that. More importantly, it disallows masking of a colon,
- * e.g. "javascript:...".

- * @fileoverview Type-safe wrappers for unsafe DOM APIs.
- *
- * This file provides type-safe wrappers for DOM APIs that can result in
- * cross-site scripting (XSS) vulnerabilities, if the API is supplied with
- * untrusted (attacker-controlled) input. Instead of plain strings, the type
- * safe wrappers consume values of types from the goog.html package whose
- * contract promises that values are safe to use in the corresponding context.
- *
- * Hence, a program that exclusively uses the wrappers in this file (i.e., whose
- * only reference to security-sensitive raw DOM APIs are in this file) is
- * guaranteed to be free of XSS due to incorrect use of such DOM APIs (modulo
- * correctness of code that produces values of the respective goog.html types,
- * and absent code that violates type safety).
- *
- * For example, assigning to an element's .innerHTML property a string that is
- * derived (even partially) from untrusted input typically results in an XSS
- * vulnerability. The type-safe wrapper goog.html.setInnerHtml consumes a value
- * of type goog.html.SafeHtml, whose contract states that using its values in a
- * HTML context will not result in XSS. Hence a program that is free of direct
- * assignments to any element's innerHTML property (with the exception of the
- * assignment to .innerHTML in this file) is guaranteed to be free of XSS due to
- * assignment of untrusted strings to the innerHTML property.

+ * The ol.DeviceOrientation class provides access to information from
+ * DeviceOrientation events. See the [HTML 5 DeviceOrientation Specification](
+ * http://www.w3.org/TR/orientation-event/) for more details.
+ *
+ * Many new computers, and especially mobile phones
+ * and tablets, provide hardware support for device orientation. Web
+ * developers targeting mobile devices will be especially interested in this
+ * class.
+ *
+ * Device orientation data are relative to a common starting point. For mobile
+ * devices, the starting point is to lay your phone face up on a table with the
+ * top of the phone pointing north. This represents the zero state. All
+ * angles are then relative to this state. For computers, it is the same except
+ * the screen is open at 90 degrees.
+ *
+ * Device orientation is reported as three angles - `alpha`, `beta`, and
+ * `gamma` - relative to the starting position along the three planar axes X, Y
+ * and Z. The X axis runs from the left edge to the right edge through the
+ * middle of the device. Similarly, the Y axis runs from the bottom to the top
+ * of the device through the middle. The Z axis runs from the back to the front
+ * through the middle. In the starting position, the X axis points to the
+ * right, the Y axis points away from you and the Z axis points straight up
+ * from the device lying flat.
+ *
+ * The three angles representing the device orientation are relative to the
+ * three axes. `alpha` indicates how much the device has been rotated around the
+ * Z axis, which is commonly interpreted as the compass heading (see note
+ * below). `beta` indicates how much the device has been rotated around the X
+ * axis, or how much it is tilted from front to back. `gamma` indicates how
+ * much the device has been rotated around the Y axis, or how much it is tilted
+ * from left to right.
+ *
+ * For most browsers, the `alpha` value returns the compass heading so if the
+ * device points north, it will be 0. With Safari on iOS, the 0 value of
+ * `alpha` is calculated from when device orientation was first requested.
+ * ol.DeviceOrientation provides the `heading` property which normalizes this
+ * behavior across all browsers for you.
+ *
+ * It is important to note that the HTML 5 DeviceOrientation specification
+ * indicates that `alpha`, `beta` and `gamma` are in degrees while the
+ * equivalent properties in ol.DeviceOrientation are in radians for consistency
+ * with all other uses of angles throughout OpenLayers.
+ *
+ * To get notified of device orientation changes, register a listener for the
+ * generic `change` event on your `ol.DeviceOrientation` instance.

- * A string-like object which represents JavaScript code and that carries the
- * security type contract that its value, as a string, will not cause execution
- * of unconstrained attacker controlled code (XSS) when evaluated as JavaScript
- * in a browser.
- *
- * Instances of this type must be created via the factory method
- * {@code goog.html.SafeScript.fromConstant} and not by invoking its
- * constructor. The constructor intentionally takes no parameters and the type
- * is immutable; hence only a default instance corresponding to the empty string
- * can be obtained via constructor invocation.
- *
- * A SafeScript's string representation can safely be interpolated as the
- * content of a script element within HTML. The SafeScript string should not be
- * escaped before interpolation.
- *
- * Note that the SafeScript might contain text that is attacker-controlled but
- * that text should have been interpolated with appropriate escaping,
- * sanitization and/or validation into the right location in the script, such
- * that it is highly constrained in its effect (for example, it had to match a
- * set of whitelisted words).
- *
- * A SafeScript can be constructed via security-reviewed unchecked
- * conversions. In this case producers of SafeScript must ensure themselves that
- * the SafeScript does not contain unsafe script. Note in particular that
- * {@code <} is dangerous, even when inside JavaScript strings, and so should
- * always be forbidden or JavaScript escaped in user controlled input. For
- * example, if {@code </script><script>evil</script>"} were
- * interpolated inside a JavaScript string, it would break out of the context
- * of the original script element and {@code evil} would execute. Also note
- * that within an HTML script (raw text) element, HTML character references,
- * such as "<" are not allowed. See

+ * @classdesc
+ * A vector object for geographic features with a geometry and other

+ *
+ * Features can be styled individually with `setStyle`; otherwise they use the

+ *
+ * Note that attribute properties are set as {@link ol.Object} properties on
+ * the feature object, so they are observable, and have get/set accessors.
+ *
+ * Typically, a feature has a single geometry property. You can set the
+ * geometry using the `setGeometry` method and get it with `getGeometry`.
+ * It is possible to store more than one geometry on a feature using attribute
+ * properties. By default, the geometry used for rendering is identified by
+ * the property name `geometry`. If you want to use another geometry property
+ * for rendering, use the `setGeometryName` method to change the attribute
+ * property associated with the geometry for the feature. For example:
+ *
+ * ```js
+ * var feature = new ol.Feature({
+ * geometry: new ol.geom.Polygon(polyCoords),
+ * labelPoint: new ol.geom.Point(labelCoords),
+ * name: 'My Polygon'
+ * });
*

- * reviewed. Avoid use of the methods in this file whenever possible; instead

/**
- * @fileoverview This file contains a class for working with keyboard events
- * that repeat consistently across browsers and platforms. It also unifies the
- * key code so that it is the same in all browsers and platforms.
- *
- * Different web browsers have very different keyboard event handling. Most
- * importantly is that only certain browsers repeat keydown events:
- * IE, Opera, FF/Win32, and Safari 3 repeat keydown events.
- * FF/Mac and Safari 2 do not.
- *
- * For the purposes of this code, "Safari 3" means WebKit 525+, when WebKit
- * decided that they should try to match IE's key handling behavior.
- * Safari 3.0.4, which shipped with Leopard (WebKit 523), has the
- * Safari 2 behavior.
- *
- * Firefox, Safari, Opera prevent on keypress
- *
- * IE prevents on keydown
- *
- * Firefox does not fire keypress for shift, ctrl, alt
- * Firefox does fire keydown for shift, ctrl, alt, meta
- * Firefox does not repeat keydown for shift, ctrl, alt, meta
- *
- * Firefox does not fire keypress for up and down in an input
- *
- * Opera fires keypress for shift, ctrl, alt, meta
- * Opera does not repeat keypress for shift, ctrl, alt, meta
- *
- * Safari 2 and 3 do not fire keypress for shift, ctrl, alt
- * Safari 2 does not fire keydown for shift, ctrl, alt
- * Safari 3 *does* fire keydown for shift, ctrl, alt
- *
- * IE provides the keycode for keyup/down events and the charcode (in the
- * keycode field) for keypress.
- *
- * Mozilla provides the keycode for keyup/down and the charcode for keypress
- * unless it's a non text modifying key in which case the keycode is provided.
- *
- * Safari 3 provides the keycode and charcode for all events.
- *
- * Opera provides the keycode for keyup/down event and either the charcode or
- * the keycode (in the keycode field) for keypress events.
- *
- * Firefox x11 doesn't fire keydown events if a another key is already held down
- * until the first key is released. This can cause a key event to be fired with
- * a keyCode for the first key and a charCode for the second key.
- *
- * Safari in keypress
- *
- * charCode keyCode which
- * ENTER: 13 13 13
- * F1: 63236 63236 63236
- * F8: 63243 63243 63243
- * ...
- * p: 112 112 112
- * P: 80 80 80
- *
- * Firefox, keypress:
- *
- * charCode keyCode which
- * ENTER: 0 13 13
- * F1: 0 112 0
- * F8: 0 119 0
- * ...
- * p: 112 0 112
- * P: 80 0 80
- *
- * Opera, Mac+Win32, keypress:
- *
- * charCode keyCode which
- * ENTER: undefined 13 13
- * F1: undefined 112 0
- * F8: undefined 119 0
- * ...
- * p: undefined 112 112
- * P: undefined 80 80
- *
- * IE7, keydown
- *
- * charCode keyCode which
- * ENTER: undefined 13 undefined
- * F1: undefined 112 undefined
- * F8: undefined 119 undefined

-/**
- * Promises provide a result that may be resolved asynchronously. A Promise may
- * be resolved by being fulfilled with a fulfillment value, rejected with a
- * rejection reason, or blocked by another Promise. A Promise is said to be
- * settled if it is either fulfilled or rejected. Once settled, the Promise
- * result is immutable.
- *
- * Promises may represent results of any type, including undefined. Rejection
- * reasons are typically Errors, but may also be of any type. Closure Promises
- * allow for optional type annotations that enforce that fulfillment values are
- * of the appropriate types at compile time.
- *
- * The result of a Promise is accessible by calling {@code then} and registering
- * {@code onFulfilled} and {@code onRejected} callbacks. Once the Promise
- * is settled, the relevant callbacks are invoked with the fulfillment value or
- * rejection reason as argument. Callbacks are always invoked in the order they
- * were registered, even when additional {@code then} calls are made from inside
- * another callback. A callback is always run asynchronously sometime after the
- * scope containing the registering {@code then} invocation has returned.
- *
- * If a Promise is resolved with another Promise, the first Promise will block
- * until the second is settled, and then assumes the same result as the second
- * Promise. This allows Promises to depend on the results of other Promises,
- * linking together multiple asynchronous operations.
- *
- * This implementation is compatible with the Promises/A+ specification and
- * passes that specification's conformance test suite. A Closure Promise may be
- * resolved with a Promise instance (or sufficiently compatible Promise-like
- * object) created by other Promise implementations. From the specification,
- * Promise-like objects are known as "Thenables".

-/**
- * @fileoverview Simple utilities for dealing with URI strings.
- *
- * This is intended to be a lightweight alternative to constructing goog.Uri
- * objects. Whereas goog.Uri adds several kilobytes to the binary regardless
- * of how much of its functionality you use, this is designed to be a set of
- * mostly-independent utilities so that the compiler includes only what is
- * necessary for the task. Estimated savings of porting is 5k pre-gzip and
- * 1.5k post-gzip. To ensure the savings remain, future developers should
- * avoid adding new functionality to existing functions, but instead create
- * new ones and factor out shared code.
- *
- * Many of these utilities have limited functionality, tailored to common
- * cases. The query parameter utilities assume that the parameter keys are
- * already encoded, since most keys are compile-time alphanumeric strings. The
- * query parameter mutation utilities also do not tolerate fragment identifiers.
- *
- * By design, these functions can be slower than goog.Uri equivalents.
- * Repeated calls to some of functions may be quadratic in behavior for IE,
- * although the effect is somewhat limited given the 2kb limit.
- *
- * One advantage of the limited functionality here is that this approach is
- * less sensitive to differences in URI encodings than goog.Uri, since these
- * functions operate on strings directly, rather than decoding them and
- * then re-encoding.
- *
- * Uses features of RFC 3986 for parsing/formatting URIs:
- * http://www.ietf.org/rfc/rfc3986.txt
- *
- * @author gboyer@google.com (Garrett Boyer) - The "lightened" design.

-/**
- * A regular expression for breaking a URI into its component parts.
- *
- * {@link http://www.ietf.org/rfc/rfc3986.txt} says in Appendix B
- * As the "first-match-wins" algorithm is identical to the "greedy"
- * disambiguation method used by POSIX regular expressions, it is natural and
- * commonplace to use a regular expression for parsing the potential five
- * components of a URI reference.
- *
- * The following line is the regular expression for breaking-down a
- * well-formed URI reference into its components.
- *
- * <pre>
- * ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?
- * 12 3 4 5 6 7 8 9
- * </pre>
- *
- * The numbers in the second line above are only to assist readability; they
- * indicate the reference points for each subexpression (i.e., each paired
- * parenthesis). We refer to the value matched for subexpression <n> as $<n>.
- * For example, matching the above expression to
- * <pre>
- * http://www.ics.uci.edu/pub/ietf/uri/#Related
- * </pre>
- * results in the following subexpression matches:
- * <pre>
- * $1 = http:
- * $2 = http
- * $3 = //www.ics.uci.edu
- * $4 = www.ics.uci.edu
- * $5 = /pub/ietf/uri/
- * $6 = <undefined>
- * $7 = <undefined>
- * $8 = #Related
- * $9 = Related
- * </pre>
- * where <undefined> indicates that the component is not present, as is the
- * case for the query component in the above example. Therefore, we can
- * determine the value of the five components as
- * <pre>
- * scheme = $2
- * authority = $4
- * path = $5
- * query = $7
- * fragment = $9
- * </pre>
- *
- * The regular expression has been modified slightly to expose the
- * userInfo, domain, and port separately from the authority.
- * The modified version yields
- * <pre>
- * $1 = http scheme
- * $2 = <undefined> userInfo -\
- * $3 = www.ics.uci.edu domain | authority
- * $4 = <undefined> port -/
- * $5 = /pub/ietf/uri/ path
- * $6 = <undefined> query without ?
- * $7 = Related fragment without #

-/**
- * @fileoverview Wrapper class for handling XmlHttpRequests.
- *
- * One off requests can be sent through goog.net.XhrIo.send() or an
- * instance can be created to send multiple requests. Each request uses its
- * own XmlHttpRequest object and handles clearing of the event callback to
- * ensure no leaks.
- *
- * XhrIo is event based, it dispatches events on success, failure, finishing,
- * ready-state change, or progress.
- *
- * The ready-state or timeout event fires first, followed by
- * a generic completed event. Then the abort, error, or success event
- * is fired as appropriate. Progress events are fired as they are
- * received. Lastly, the ready event will fire to indicate that the
- * object may be used to make another request.
- *
- * The error event may also be called before completed and
- * ready-state-change if the XmlHttpRequest.open() or .send() methods throw.
- *
- * This class does not support multiple requests, queuing, or prioritization.
- *
- * When progress events are supported by the browser, and progress is
- * enabled via .setProgressEventsEnabled(true), the
- * goog.net.EventType.PROGRESS event will be the re-dispatched browser
- * progress event.
- *
- * Tested = IE6, FF1.5, Safari, Opera 8.5
- *
- * TODO(user): Error cases aren't playing nicely in Safari.

- // includes:
- //
- // - Only drawing pixels that will be visible.
- // - Not re-drawing pixels/tiles that are already correct.
- // - Minimizing calls to clearRect.
- // - Never shrink the canvas. Just make it bigger when necessary.
- // Re-sizing the canvas also clears it, which further means
- // re-creating it (expensive).
- //
- // The various steps performed by this functions:
- //
- // - Create a canvas element if none has been created yet.
- //
- // - Make the canvas bigger if it's too small. Note that we never shrink
- // the canvas, we just make it bigger when necessary, when rotating for
- // example. Note also that the canvas always contains a whole number
- // of tiles.
- //
- // - Invalidate the canvas tile range (renderedCanvasTileRange_ = null)
- // if (1) the canvas has been enlarged, or (2) the zoom level changes,
- // or (3) the canvas tile range doesn't contain the required tile
- // range. This canvas tile range invalidation thing is related to
- // an optimization where we attempt to redraw as few pixels as
- // possible on each prepareFrame call.
- //
- // - If the canvas tile range has been invalidated we reset
- // renderedCanvasTileRange_ and reset the renderedTiles_ array.
- // The renderedTiles_ array is the structure used to determine
- // the canvas pixels that need not be redrawn from one prepareFrame
- // call to another. It records while tile has been rendered at
- // which position in the canvas.
- //
- // - We then determine the tiles to draw on the canvas. Tiles for
- // the target resolution may not be loaded yet. In that case we
- // use low-resolution/interim tiles if loaded already. And, if
- // for a non-yet-loaded tile we haven't found a corresponding
- // low-resolution tile we indicate that the pixels for that
- // tile must be cleared on the canvas. Note: determining the
- // interim tiles is based on tile extents instead of tile
- // coords, this is to be able to handler irregular tile grids.
- //
- // - We're now ready to render. We start by calling clearRect
- // for the tiles that aren't loaded yet and are not fully covered
- // by a low-resolution tile (if they're loaded, we'll draw them;
- // if they're fully covered by a low-resolution tile then there's
- // no need to clear). We then render the tiles "back to front",
- // i.e. starting with the low-resolution tiles.
- //
- // - After rendering some bookkeeping is performed (updateUsedTiles,
- // etc.). manageTilePyramid is what enqueue tiles in the tile
- // queue for loading.
- //
- // - The last step involves updating the image transform matrix,
- // which will be used by the map renderer for the final
- // composition and positioning.

- * @classdesc
- * The map is the core component of OpenLayers. For a map to render, a view,
- * one or more layers, and a target container are needed:
- *
- * var map = new ol.Map({
- * view: new ol.View({
- * center: [0, 0],
- * zoom: 1
- * }),
- * layers: [
- * new ol.layer.Tile({
- * source: new ol.source.MapQuest({layer: 'osm'})
- * })
- * ],
- * target: 'map'
- * });
- *
- * The above snippet creates a map using a {@link ol.layer.Tile} to display
- * {@link ol.source.MapQuest} OSM data and render it to a DOM element with the
- * id `map`.
- *
- * The constructor places a viewport container (with CSS class name
- * `ol-viewport`) in the target element (see `getViewport()`), and then two
- * further elements within the viewport: one with CSS class name
- * `ol-overlaycontainer-stopevent` for controls and some overlays, and one with
- * CSS class name `ol-overlaycontainer` for other overlays (see the `stopEvent`
- * option of {@link ol.Overlay} for the difference). The map itself is placed in
- * a further element within the viewport, either DOM or Canvas, depending on the
- * renderer.
- *
- * Layers are stored as a `ol.Collection` in layerGroups. A top-level group is
- * provided by the library. This is what is accessed by `getLayerGroup` and
- * `setLayerGroup`. Layers entered in the options are added to this group, and
- * `addLayer` and `removeLayer` change the layer collection in the group.
- * `getLayers` is a convenience function for `getLayerGroup().getLayers()`.
- * Note that `ol.layer.Group` is a subclass of `ol.layer.Base`, so layers
- * entered in the options or added with `addLayer` can be groups, which can
- * contain further groups, and so on.
- *

/**
- * @classdesc
- * The ol.DeviceOrientation class provides access to information from
- * DeviceOrientation events. See the [HTML 5 DeviceOrientation Specification](
- * http://www.w3.org/TR/orientation-event/) for more details.
- *
- * Many new computers, and especially mobile phones
- * and tablets, provide hardware support for device orientation. Web
- * developers targeting mobile devices will be especially interested in this
- * class.
- *
- * Device orientation data are relative to a common starting point. For mobile
- * devices, the starting point is to lay your phone face up on a table with the
- * top of the phone pointing north. This represents the zero state. All
- * angles are then relative to this state. For computers, it is the same except
- * the screen is open at 90 degrees.
- *
- * Device orientation is reported as three angles - `alpha`, `beta`, and
- * `gamma` - relative to the starting position along the three planar axes X, Y
- * and Z. The X axis runs from the left edge to the right edge through the
- * middle of the device. Similarly, the Y axis runs from the bottom to the top
- * of the device through the middle. The Z axis runs from the back to the front
- * through the middle. In the starting position, the X axis points to the
- * right, the Y axis points away from you and the Z axis points straight up
- * from the device lying flat.
- *
- * The three angles representing the device orientation are relative to the
- * three axes. `alpha` indicates how much the device has been rotated around the
- * Z axis, which is commonly interpreted as the compass heading (see note
- * below). `beta` indicates how much the device has been rotated around the X
- * axis, or how much it is tilted from front to back. `gamma` indicates how
- * much the device has been rotated around the Y axis, or how much it is tilted
- * from left to right.
- *
- * For most browsers, the `alpha` value returns the compass heading so if the
- * device points north, it will be 0. With Safari on iOS, the 0 value of
- * `alpha` is calculated from when device orientation was first requested.
- * ol.DeviceOrientation provides the `heading` property which normalizes this
- * behavior across all browsers for you.
- *
- * It is important to note that the HTML 5 DeviceOrientation specification
- * indicates that `alpha`, `beta` and `gamma` are in degrees while the
- * equivalent properties in ol.DeviceOrientation are in radians for consistency
- * with all other uses of angles throughout OpenLayers.
+ * Read all features from a KML source. MultiGeometries are converted into
+ * GeometryCollections if they are a mix of geometry types, and into MultiPoint/
+ * MultiLineString/MultiPolygon if they are all of the same type.
*
- * @see http://www.w3.org/TR/orientation-event/
- *
- * To get notified of device orientation changes, register a listener for the
- * generic `change` event on your `ol.DeviceOrientation` instance.

/**
- * A Deferred represents the result of an asynchronous operation. A Deferred
- * instance has no result when it is created, and is "fired" (given an initial
- * result) by calling {@code callback} or {@code errback}.
- *
- * Once fired, the result is passed through a sequence of callback functions
- * registered with {@code addCallback} or {@code addErrback}. The functions may
- * mutate the result before it is passed to the next function in the sequence.
- *
- * Callbacks and errbacks may be added at any time, including after the Deferred
- * has been "fired". If there are no pending actions in the execution sequence
- * of a fired Deferred, any new callback functions will be called with the last
- * computed result. Adding a callback function is the only way to access the
- * result of the Deferred.
+ * @classdesc
+ * Interaction for selecting vector features. By default, selected features are
+ * styled differently, so this interaction can be used for visual highlighting,
+ * as well as selecting features for other actions, such as modification or
+ * output. There are three ways of controlling which features are selected:
+ * using the browser event as defined by the `condition` and optionally the
+ * `toggle`, `add`/`remove`, and `multi` options; a `layers` filter; and a
+ * further feature filter using the `filter` option.
*
- * If a Deferred operation is canceled, an optional user-provided cancellation
- * function is invoked which may perform any special cleanup, followed by firing
- * the Deferred's errback sequence with a {@code CanceledError}. If the
- * Deferred has already fired, cancellation is ignored.
+ * Selected features are added to an internal unmanaged layer.
*
- * Deferreds may be templated to a specific type they produce using generics
- * with syntax such as:
- * <code>
- * /** @type {goog.async.Deferred<string>} */
- * var d = new goog.async.Deferred();
- * // Compiler can infer that foo is a string.
- * d.addCallback(function(foo) {...});
- * d.callback('string'); // Checked to be passed a string
- * </code>
- * Since deferreds are often used to produce different values across a chain,
- * the type information is not propagated across chains, but rather only
- * associated with specifically cast objects.
- *
- * @param {Function=} opt_onCancelFunction A function that will be called if the
