List of all members.

Public Member Functions
virtual void	ClearCache (MgMap *map)=0
	Clears the entire tile cache for the given map. Tiles for all base map layer groups and finite scales will be removed.
virtual void	ClearCache (MgResourceIdentifier *tileSet)=0
	Clears the entire tile cache for the given tile set. Tiles for all base map layer groups and finite scales will be removed.
virtual INT32	GetDefaultTileSizeX ()=0
	Returns the default width of a tile.
virtual INT32	GetDefaultTileSizeX (MgResourceIdentifier *tileSet)=0
	Returns the default width of a tile.
virtual INT32	GetDefaultTileSizeY ()=0
	Returns the default height of a tile.
virtual INT32	GetDefaultTileSizeY (MgResourceIdentifier *tileSet)=0
	Returns the default height of a tile.
virtual MgByteReader *	GetTile (MgMap *map, CREFSTRING baseMapLayerGroupName, INT32 tileColumn, INT32 tileRow)=0
	Returns the specified base map tile for the given map. If a cached tile image exists it will return it, otherwise the tile is rendered and added to the cache.
virtual MgByteReader *	GetTile (MgResourceIdentifier *resource, CREFSTRING baseMapLayerGroupName, INT32 tileColumn, INT32 tileRow, INT32 scaleIndex)=0
	Returns the specified base map tile for the given map or tile set. If a cached tile image exists it will return it, otherwise the tile is rendered and added to the cache.
virtual MgByteReader *	GetTileProviders ()=0
	Returns the XML description of available tile providers, along with supported connection parameters. This provides sufficient information for client applications to build rich editor user interfaces for editing Tile Set Definitions.
