ChamplainFileCache is a cache that stores and retrieves tiles from the file system. Tiles most frequently loaded gain in "popularity". This popularity is taken into account when purging the cache.
struct ChamplainFileCache;
The ChamplainFileCache structure contains only private data and should be accessed using the provided API
Since 0.6
ChamplainFileCache * champlain_file_cache_new_full (guint size_limit
,const gchar *cache_dir
,ChamplainRenderer *renderer
);
Constructor of ChamplainFileCache.
|
maximum size of the cache in bytes |
|
the directory where the cache is created. When cache_dir == NULL, a cache in ~/.cache/champlain is used. [allow-none] |
|
the ChamplainRenderer used for tiles rendering |
Returns : |
a constructed ChamplainFileCache |
Since 0.8
void champlain_file_cache_set_size_limit (ChamplainFileCache *file_cache
,guint size_limit
);
Sets the cache size limit in bytes.
|
a ChamplainFileCache |
|
the cache limit in bytes |
Since 0.4
guint champlain_file_cache_get_size_limit (ChamplainFileCache *file_cache
);
Gets the cache size limit in bytes.
|
a ChamplainFileCache |
Returns : |
size limit |
Since 0.4
const gchar * champlain_file_cache_get_cache_dir (ChamplainFileCache *file_cache
);
Gets the directory where the cache database is stored.
|
a ChamplainFileCache |
Returns : |
the directory |
Since 0.6
void champlain_file_cache_purge (ChamplainFileCache *file_cache
);
Purge the cache from the less popular tiles until cache's size limit is reached.

Since 0.4
void champlain_file_cache_purge_on_idle (ChamplainFileCache *file_cache
);
Purge the cache from the less popular tiles until cache's size limit is reached. This is a non blocking call as the purge will happen when the application is idle
