CleanupCache()

template<class T >

void osmscout::MapTileCache< T >::CleanupCache

(

)

Cleanup the cache.

Free least recently used tiles until the given maximum cache size is reached again.

GetCachedTile()

template<class T >

MapTileCache< T >::TRef osmscout::MapTileCache< T >::GetCachedTile

(

const TileKey &

key

)

const

Return the cache tiles with the given id.

If the tiles is not cache, an empty reference will be returned.

GetTile()

template<class T >

MapTileCache< T >::TRef osmscout::MapTileCache< T >::GetTile

(

const TileKey &

key

)

const

Return the tile with the given id.

If the tile is not currently cached return an empty and unassigned tile and move it to the front of the cache.

GetTilesForBoundingBox()

template<class T >

void osmscout::MapTileCache< T >::GetTilesForBoundingBox	(	const Magnification &	magnification,
		const GeoBox &	boundingBox,
		std::list< typename MapTileCache< T >::TRef > &	tiles
	)		const

Return all tile necessary for covering the given boundingbox using the given magnification.

SetSize()

template<class T >

void osmscout::MapTileCache< T >::SetSize

(

size_t

cacheSize

)

Change the size of the cache.

Cache will be cleaned immediately.
