geoRectToRect (geoRect, opt_zoom) : {H.math.Rect}

This method transforms a geo-rectangle to a projected geometrical rectangle at the current projection zoom level or at the zoom level provided by the caller.

getTileBounds (boundingBox, zoom) : {H.math.Rect}

This method retrieves the tile grid boundary for a projected bounding box.

requestTile (x, y, z, cacheOnly) : {(H.map.provider.Tile | undefined)}

This method requests a single tile based on the tile coordinates. It returns either a Tile object if it is already loaded or undefined, in which case it starts loading the tile.

cancelTile (x, y, z)

This method cancels a previous request for a tile.

getProviderTiles (tileGridBoundary, isCDB, zoomLevel, cacheOnly, prioCenter, opt_requesterId) : {H.map.layer.ITileLayer.Response}

This method requests tiles from a data source (provider). It can return a set of tiles which are currently loaded. All tiles which are not yet loaded are included in the response as soon as they become available during subsequent calls.

getProvider () : {H.map.provider.Provider}

This method returns the provider which feeds this layer with data.

isValid (zoomLevel) : {boolean}

This method checks if a zoom level can be served by the given layer.

setMin (min) : {H.map.layer.Layer}

This method sets the minimum zoom level at which the given layer provides content.

setMax (max) : {H.map.layer.Layer}

This method sets the maximum zoom level at which the given layer provides content.

getCopyrights (boundingBox, level) : {?Array<H.map.ICopyright>}

This method retrieves the copyright of the current data provider.

Note: This function must be overridden by any class derived from Layer. The default implementation returns null.

addEventListener (type, handler, opt_capture, opt_scope)

This method adds a listener for a specific event.

Note that to prevent potential memory leaks, you must either call removeEventListener or dispose on the given object when you no longer need it.

removeEventListener (type, handler, opt_capture, opt_scope)

This method removes a previously added listener from the EventTarget instance.

dispatchEvent (evt)

This method dispatches an event on the EventTarget object.

dispose ()

This method removes listeners from the given object. Classes that extend EventTarget may need to override this method in order to remove references to DOM Elements and additional listeners.

addOnDisposeCallback (callback, opt_scope)

This method adds a callback which is triggered when the EventTarget object is being disposed.
