Class KeyLinkMap<K,V>

java.lang.Object
  com.caucho.portal.generic.KeyLinkMap<K,V>

All Implemented Interfaces:

java.util.Map<K,V>

public class KeyLinkMap<K,V>
extends java.lang.Object
implements java.util.Map<K,V>

A Map that wraps another map and uses different keys in the wrapped map than the keys that are exposed. The constructor is passed the map to be wrapped, and a keyLinkMap that maps keys as they are used by users of the map to different keys that are really used in the wrapped map. If a key is used that is not int the keyLinkMap, the key is used unchanged in the wrapped map.
