DeleteStoreRoom() public method

Deletes the store room specified in the connection descriptor. If this data source doesn't use a store room, this method should be a no-op. If this data source DOES use store rooms, but support for adding them is not implemented yet, this should throw a NotImplementedException. Store room typically corresponds to "table". If there is no store room with the given name, this should be a no-op.

public DeleteStoreRoom ( ClassMapping mapping ) : void
mapping	ClassMapping	ClassMapping for the data that was stored in this room.
return	void
