All Implemented Interfaces:

MemoryCache

public class FIFOLimitedMemoryCache
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 cache clearing is processed by FIFO principle.

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.

Since:

1.0.0
