Interface TileCache

All Superinterfaces:

Map<TileCacheKey,TilingScheme.Tile>

All Known Implementing Classes:

LRUTileCache

public interface TileCache
extends Map<TileCacheKey,TilingScheme.Tile>

A TileCache object stores a set of TilingScheme.Tile objects and allows for their retrieval. A tile cache may be used to speed up access to frequently-used data tiles.

Method Details

setCacheSizeLimit

void setCacheSizeLimit(int bytes)

Sets the total cache size limit in bytes.

Parameters:

bytes - the number of bytes allowed in the cache. The cache must delete tiles if adding a tile would go over this limit.

getCacheSizeLimit

int getCacheSizeLimit()

Gets the total cache size limit in bytes.

Returns:

the number of bytes allowed in the cache. The cache must delete tiles if adding a tile would go over this limit.

getCacheSize

int getCacheSize()

Gets the total cache size in bytes.

Returns:

the number of bytes currently in the cache.
