Method Detail

buildConcurrentLRUCacheMap

public static <K,V> com.googlecode.concurrentlinkedhashmap.ConcurrentLinkedHashMap<K,V> buildConcurrentLRUCacheMap(int _maxSize)

Creates a new com.googlecode.concurrentlinkedhashmap.ConcurrentLinkedHashMap with the given maximum size. Uses a concurrency Level of 16. e.g. CacheMapBuilder.<Long, String>buildConcurrentLRUCacheMap(10).

Parameters:

_maxSize - maximum allowed cache size, value > 0

Returns:

A new, thread-save, size-limited Map

buildLRUCacheMap

public static <K,V> java.util.LinkedHashMap<K,V> buildLRUCacheMap(int _maxSize)

Creates a new LinkedHashMap with the given maximum size. The resulting Map is not thread save. If you need thread-safety, use buildConcurrentLRUCacheMap(int) instead.

Parameters:

_maxSize - maximum allowed cache size, value > 0

Returns:

A new, size-limited Map
