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

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

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 (rectBounds, zoom) : {H.math.Rect}

This method retrieves the tile grid bounds for a projected rectangle.

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 (tileBounds, 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.

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 (bounds, 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.

requestMarkers (boundingRect, zoomLevel, cacheOnly, prioCenter) : {(H.map.layer.IMarkerLayer.Response | H.map.layer.IMarkerLayer.TiledResponse)}

This method requests marker objects for a bounding rectangle.

The implementation of this method must return all marker objects which are contained within the bounding rectangle.

The response object returned by this method must contain the number of objects which intersect with the bounding rectangle.

This method is called by the renderer in each rendering cycle. An implementing object must make sure that calling this method does not impede the rendering process.

requestDomMarkers (boundingRect, zoomLevel, cacheOnly, prioCenter) : {(H.map.layer.IMarkerLayer.Response | H.map.layer.IMarkerLayer.TiledResponse)}

This method requests DOM marker objects for a bounding rectangle.

The implementation of this method must return all DOM marker objects which are contained within the bounding rectangle.

The response object returned by this method must contain the number of objects which intersect with the bounding rectangle.

This method is called by the renderer in each rendering cycle. An implementing object must make sure that calling this method does not impede the rendering process.
