DefaultConversationContext

public abstract class HashMonitoredContext<K,V,T extends MonitoredContext<K,V,T>>
extends HashMap<K,V>
implements MonitoredContext<K,V,T>

A Serializable Hash implementation of the Map and Timeoutable interfaces. Resets its own remaining time whenever the wrapped HashMap is accessed.
