org.jasig.portal.utils.cache
Class MapCacheProvider<K extends Serializable,V>

java.lang.Object
  org.jasig.portal.utils.cache.MapCacheProvider<K,V>

All Implemented Interfaces:

Map<K,V>

public class MapCacheProvider<K extends Serializable,V>
extends Object
implements Map<K,V>

Hides a CacheProviderFacade behind a the Map interface. Only the following methods are supported:

• clear()
• containsKey(Object)
• get(Object)
• put(Serializable, Object)
• putAll(Map)
• remove(Object)

The put(Serializable, Object) and remove(Object) methods call get(Object) before performing the requested operation to be able to return the 'old' value.
