Class ExpirableValuesPseudoMap<K,V,U>

java.lang.Object

com.zfabrik.resources.util.ExpirableValuesPseudoMap<K,V,U>

public class ExpirableValuesPseudoMap<K,V,U>
extends java.lang.Object

A map wrapper that manages a map over expirable values. Note: if an invalidation queue has been set, this map will NOT remove invalidated values from the map but relies on external processing to do so.
