addEventListener (type, handler, opt_capture, opt_scope)

This method adds a listener for a specific event triggered by the object.

removeEventListener (type, handler, opt_capture, opt_scope)

This method removes a previously added listener from the event target

dispatchEvent (evt)

This method dispatches an event on the event target 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 TrafficIncidentsProvider object is being disposed of.

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

This method retrieves the copyright information for map content in a certain geographical area displayed at a specific zoom level.

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

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

This method request a tile.

cancelTile (x, y, z)

This method cancels a tile request based on the tile coordinates (column, row) and zoom level.

cancelTileByKey (tileKey)

This method cancels a tile request based on a tile key.

getTileKey (x, y, z) : {string}

This method creates a tile key consisting of the provider's UID, and the x, y and z coordinates of the tile, seperated by underscores, for example "4711_7_42_23".

getCache () : {H.util.Cache}

This method retrieves a tile cache.

requestInternal (x, y, z, onResponse, onError) : {H.util.ICancelable}

This method request a tile from the remote service.

reload (hard)

This method instructs the provider to reload data from its source.

Two reload modes are supported:

• hard: This method immediately removes the cached tiles from the tile cache and forces the provider to re-fetch the tiles. Any currently cached tiles are not used for rendering.
• soft: This method marks tiles as invalid and requests the tiles to be re-fetched at the earliest opportunity. The provider does not invalidate the cache immediately in this case. This means that cached tiles can still be rendered while the updated tiles are fetched.

invalidateObject (marker, flags)

This method signals to the given provider that a map object has changed. The method marks the tile that contains the object as invalid and triggers a call to dispatchUpdate().

providesDomMarkers () : {boolean}

This method checks whether the given provider provides H.map.DomMarker objects.
