Method Detail

getTileSource

public ITileSource getTileSource()

getUsesDataConnection

public boolean getUsesDataConnection()

Description copied from class: MapTileModuleProviderBase

Returns true if implementation uses a data connection, false otherwise. This value is used to determine if this provider should be skipped if there is no data connection.
