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.

ChamplainMapSourceChain * champlain_map_source_chain_new
(void);
Constructor of ChamplainMapSourceChain.
Returns : |
a new empty ChamplainMapSourceChain. |

void champlain_map_source_chain_push (ChamplainMapSourceChain *source_chain,ChamplainMapSource *map_source);
Pushes a map source into the chain.
|
a ChamplainMapSourceChain |
|
the ChamplainMapSource to be pushed into the chain |
Since 0.6
void champlain_map_source_chain_pop (ChamplainMapSourceChain *source_chain);
Pops a map source from the top of the stack from the chain.
