Class PersistableMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

org.jivesoftware.util.PersistableMap<K,V>

Type Parameters:

K - key. see Map

V - value. see Map

All Implemented Interfaces:

Serializable, Cloneable, Map<K,V>

Direct Known Subclasses:

DefaultGroupPropertyMap

public abstract class PersistableMap<K,V>
extends HashMap<K,V>

This acts as a tag interface. It has no functionality, but it serves to make more clear the intention to pass around a special type of map.
