Package org.apache.maven.impl.cache

Class SoftIdentityMap<K,V>

java.lang.Object

org.apache.maven.impl.cache.SoftIdentityMap<K,V>

Type Parameters:

K - the type of keys maintained by this map

V - the type of mapped values

All Implemented Interfaces:

Map<K,V>

public class SoftIdentityMap<K,V>
extends Object
implements Map<K,V>

A Map implementation that uses soft references for both keys and values, and compares keys using identity (==) rather than equals().
