Description

This map source simplifies creation of map chains by providing two functions for their creation and modification in a stack-like manner: champlain_map_source_chain_push() and champlain_map_source_chain_pop(). For instance, to create a chain consisting of ChamplainMemoryCache, ChamplainFileCache and ChamplainNetworkTileSource, the map sources have to be pushed into the chain in the reverse order starting from ChamplainNetworkTileSource. After its creation, ChamplainMapSourceChain behaves as a chain of map sources it contains.
