• swigCreatePolymorphicInstance

  public static PersistentCacheTileDataSource swigCreatePolymorphicInstance(long cPtr,
                                                                            boolean cMemoryOwn)

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

• isCacheOnlyMode

  public boolean isCacheOnlyMode()

  Returns the state of cache only mode.
  

  Returns:

  True when cache only mode is enabled, false otherwise.

• setCacheOnlyMode

  public void setCacheOnlyMode(boolean enabled)

  Switches the datasource to 'cache only' mode or switches back from the mode.

  By default, cache only mode is off.
  

  Parameters:

  enabled - True when the mode should be enabled, false otherwise.

• close

  public void close()

  Close the cache database. The datasource will still work afterwards,
  but all requests will be directed to the original datasource.

  public TileData loadTile(MapTile mapTile)

  Description copied from class: TileDataSource
  Loads the specified tile.
  

  Overrides:

  loadTile in class TileDataSource

  Parameters:

  mapTile - The tile to load.

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

  Overrides:

  swigGetClassName in class CacheTileDataSource

  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 CacheTileDataSource

  Returns:

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