Class ManagedConcurrentValueMap<K,V>

java.lang.Object

org.codehaus.groovy.util.ManagedConcurrentValueMap<K,V>

Type Parameters:

K - the key type

V - the value type

public class ManagedConcurrentValueMap<K,V>
extends java.lang.Object

This is a basic implementation of a map able to forget its values. This map uses internally a ConcurrentHashMap, thus should be safe for concurrency. hashcode and equals are used to find the entries and should thus be implemented properly for the keys. This map does not support null keys.
