所有已实现的接口:

MemoryCache

public class LRULimitedMemoryCache
extends LimitedMemoryCache

Limited bitmap cache. Provides bitmaps storing. Size of all stored bitmaps will not to exceed size limit. When cache reaches limit size then the least recently used bitmap is deleted from cache.

NOTE: This cache uses strong and weak references for stored Bitmaps. Strong references - for limited count of Bitmaps (depends on cache size), weak references - for all other cached Bitmaps.

从以下版本开始:

1.3.0
