ChamplainMapSourceChainChamplainMapSourceChain — A map source simplifying creation of source chains |
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.
Functions
champlain_map_source_chain_new ()
ChamplainMapSourceChain *
champlain_map_source_chain_new (void
);
Constructor of ChamplainMapSourceChain.
Since 0.6
champlain_map_source_chain_push ()
void champlain_map_source_chain_push (ChamplainMapSourceChain *source_chain
,ChamplainMapSource *map_source
);
Pushes a map source into the chain.
Since 0.6
champlain_map_source_chain_pop ()
void
champlain_map_source_chain_pop (ChamplainMapSourceChain *source_chain
);
Pops a map source from the top of the stack from the chain.
