- * 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
- * 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.
- *

- * @extends {ol.Object}

-/**
- * @classdesc
- * A control is a visible widget with a DOM element in a fixed position on the
- * screen. They can involve user input (buttons), or be informational only;
- * the position is determined using CSS. By default these are placed in the
- * container with CSS class name `ol-overlaycontainer-stopevent`, but can use
- * any outside DOM element.
- *
- * This is the base class for controls. You can use it for simple custom
- * controls by creating the element with listeners, creating an instance:
- * ```js
- * var myControl = new ol.control.Control({element: myElement});
- * ```
- * and then adding this to the map.
- *
- * The main advantage of having this as a control rather than a simple separate
- * DOM element is that preventing propagation is handled for you. Controls
- * will also be `ol.Object`s in a `ol.Collection`, so you can use their
- * methods.
- *
- * You can also extend this base for your own control class. See
- * examples/custom-controls for an example of how to do this.

- * 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.
- *
- * 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.
- *
- * To get notified of device orientation changes, register a listener for the
- * generic `change` event on your `ol.DeviceOrientation` instance.
- *
- * @see {@link http://www.w3.org/TR/orientation-event/}

- * 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'

- *

- * var poly = feature.getGeometry();
- *
- * // Render the feature as a point using the coordinates from labelPoint
- * feature.setGeometryName('labelPoint');

- * @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.OSM()
- * })
- * ],
- * target: 'map'
- * });
- *
- * The above snippet creates a map using a {@link ol.layer.Tile} to display
- * {@link ol.source.OSM} 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.
- *
- * 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.

Each state has a corresponding getter and setter, e.g.\n * `getCenter` and `setCenter` for the `center` state.\n *\n * An View has a `projection`. The projection determines the\n * coordinate system of the center, and its units determine the units of the\n * resolution (projection units per pixel). The default projection is\n * Spherical Mercator (EPSG:3857).\n *\n * ### The constraints\n *\n * `setCenter`, `setResolution` and `setRotation` can be used to change the\n * states of the view. Any value can be passed to the setters. And the value\n * that is passed to a setter will effectively be the value set in the view,\n * and returned by the corresponding getter.\n *\n * But a View object also has a *resolution constraint*, a\n * *rotation constraint* and a *center constraint*.\n *\n * As said above, no constraints are applied when the setters are used to set\n * new states for the view. Applying constraints is done explicitly through\n * the use of the `constrain*` functions (`constrainResolution` and\n * `constrainRotation` and `constrainCenter`).\n *\n * The main users of the constraints are the interactions and the\n * controls. For example, double-clicking on the map changes the view to\n * the \"next\" resolution. And releasing the fingers after pinch-zooming\n * snaps to the closest resolution (with an animation).\n *\n * The *resolution constraint* snaps to specific resolutions. It is\n * determined by the following options: `resolutions`, `maxResolution`,\n * `maxZoom`, and `zoomFactor`. If `resolutions` is set, the other three\n * options are ignored. See documentation for each option for more\n * information.\n *\n * The *rotation constraint* snaps to specific angles. It is determined\n * by the following options: `enableRotation` and `constrainRotation`.\n * By default the rotation value is snapped to zero when approaching the\n * horizontal.\n *\n * The *center constraint* is determined by the `extent` option. By\n * default the center is not constrained at all.\n *\n * @api\n */\nvar View = /*@__PURE__*/(function (BaseObject) {\n function View(opt_options) {\n BaseObject.call(this);\n\n var options = assign({}, opt_options);\n\n /**\n * @private\n * @type {Array<number>}\n */\n this.hints_ = [0, 0];\n\n /**\n * @private\n * @type {Array<Array<Animation>>}\n */\n this.animations_ = [];\n\n /**\n * @private\n * @type {number|undefined}\n */\n this.updateAnimationKey_;\n\n this.updateAnimations_ = this.updateAnimations_.bind(this);\n\n /**\n * @private\n * @const\n * @type {import(\"./proj/Projection.js\").default}\n */\n this.projection_ = createProjection(options.projection, 'EPSG:3857');\n\n this.applyOptions_(options);\n }\n\n if ( BaseObject ) View.__proto__ = BaseObject;\n View.prototype = Object.create( BaseObject && BaseObject.prototype );\n View.prototype.constructor = View;\n\n /**\n * Set up the view with the given options.\n * @param {ViewOptions} options View options.\n */\n View.prototype.applyOptions_ = function applyOptions_ (options) {\n\n /**\n * @type {Object<string, *>}\n */\n var properties = {};\n properties[ViewProperty.CENTER] = options.center !== undefined ?\n options.center : null;\n\n var resolutionConstraintInfo = createResolutionConstraint(options);\n\n /**\n * @private\n * @type {number}\n */\n this.maxResolution_ = resolutionConstraintInfo.maxResolution;\n\n /**\n * @private\n * @type {number}\n */\n this.minResolution_ = resolutionConstraintInfo.minResolution;\n\n /**\n * @private\n * @type {number}\n */\n this.zoomFactor_ = resolutionConstraintInfo.zoomFactor;\n\n /**\n * @private\n * @type {Array<number>|undefined}\n */\n this.resolutions_ = options.resolutions;\n\n /**\n * @private\n * @type {number}\n */\n this.minZoom_ = resolutionConstraintInfo.minZoom;\n\n var centerConstraint = createCenterConstraint(options);\n var resolutionConstraint = resolutionConstraintInfo.constraint;\n var rotationConstraint = createRotationConstraint(options);\n\n /**\n * @private\n * @type {Constraints}\n */\n this.constraints_ = {\n center: centerConstraint,\n resolution: resolutionConstraint,\n rotation: rotationConstraint\n };\n\n if (options.resolution !== undefined) {\n properties[ViewProperty.RESOLUTION] = options.resolution;\n } else if (options.zoom !== undefined) {\n properties[ViewProperty.RESOLUTION] = this.constrainResolution(\n this.maxResolution_, options.zoom - this.minZoom_);\n\n if (this.resolutions_) { // in case map zoom is out of min/max zoom range\n properties[ViewProperty.RESOLUTION] = clamp(\n Number(this.getResolution() || properties[ViewProperty.RESOLUTION]),\n this.minResolution_, this.maxResolution_);\n }\n }\n properties[ViewProperty.ROTATION] = options.rotation !== undefined ? options.rotation : 0;\n this.setProperties(properties);\n\n /**\n * @private\n * @type {ViewOptions}\n */\n this.options_ = options;\n\n };\n\n /**\n * Get an updated version of the view options used to construct the view.
