Creates a polymorphic instance of the given native object. This is used internally by the SDK.

notifyTilesChanged

public void notifyTilesChanged(boolean removeTiles)

Description copied from class: TileDataSource

Notifies listeners that the tiles have changed. Action taken depends on the implementation of the
listeners, but generally all cached tiles will be reloaded. If the removeTiles flag is set all caches will be cleared
prior to reloading, if it's not set then the reloaded tiles will replace the old tiles in caches as they finish loading.

Overrides:

notifyTilesChanged in class TileDataSource

Parameters:

removeTiles - The remove tiles flag.

clear

public void clear()

Clear the cache.

getCapacity

public long getCapacity()

Returns the compressed tile cache capacity.

Returns:

The compressed tile cache capacity in bytes.

setCapacity

public void setCapacity(long capacity)

Sets the cache capacity.

swigGetClassName

public java.lang.String swigGetClassName()

Returns the actual class name of this object. This is used internally by the SDK.

Overrides:

swigGetClassName in class TileDataSource

Returns:

The class name of this object.

swigGetDirectorObject

public java.lang.Object swigGetDirectorObject()

Returns the connected director object. This is used internally by the SDK.

Overrides:

swigGetDirectorObject in class TileDataSource

Returns:

The connected director object or null if director is not connected.
