All Implemented Interfaces:
java.util.Map<K,V>

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

Waitable hash map provides an additional method to the map interface: waitFor(key, timeout). This method will wait until specified key is found in the map. This map does not allow null key or null value.
