Class MapCopy<K,V>

java.lang.Object
  java.util.AbstractMap<K,V>
      org.jboss.cache.util.MapCopy<K,V>

All Implemented Interfaces:

java.io.Serializable, java.util.Map<K,V>

public class MapCopy<K,V>
extends java.util.AbstractMap<K,V>
implements java.io.Serializable

Contains a fixed array of read-only map entries, from a copy of an existing map. This class is more lightweight for places where the copied map will just be iterated over.

This map is strictly read-only, and map modification methods (as well as modifications over iterators) will throw UnsupportedOperationExceptions.
