Class DelegatingMap<K,V>

java.lang.Object
  edu.rice.cs.plt.collect.DelegatingMap<K,V>

All Implemented Interfaces:

LambdaMap<K,V>, Lambda<K,V>, Composite, Serializable, Map<K,V>

public class DelegatingMap<K,V>
extends Object
implements LambdaMap<K,V>, Composite, Serializable

A map that delegates all operations to a wrapped map. Subclasses can be defined that override a few of the methods, while maintaining the default delegation behavior in most cases.
