Method Detail

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.

Specified by:

getUsesDataConnection in class MapTileModuleProviderBase

Returns:

true if implementation uses a data connection, false otherwise

getName

protected String getName()

Description copied from class: MapTileModuleProviderBase

Gets the human-friendly name assigned to this tile provider.

Specified by:

getName in class MapTileModuleProviderBase

Returns:

the thread name

getThreadGroupName

protected String getThreadGroupName()

Description copied from class: MapTileModuleProviderBase

Gets the name assigned to the thread for this provider.

Specified by:

getThreadGroupName in class MapTileModuleProviderBase

Returns:

the thread name

getTileLoader

protected Runnable getTileLoader()

Description copied from class: MapTileModuleProviderBase

It is expected that the implementation will construct an internal member which internally implements a MapTileModuleProviderBase.TileLoader. This method is expected to return a that internal member to methods of the parent methods.

Specified by:

getTileLoader in class MapTileModuleProviderBase

Returns:

the internal member of this tile provider.

getMinimumZoomLevel

public int getMinimumZoomLevel()

Description copied from class: MapTileModuleProviderBase
