Class DefaultGroupPropertyMap<K,V>

java.lang.Object
  java.util.AbstractMap<K,V>
      java.util.HashMap<K,V>
          org.jivesoftware.openfire.group.DefaultGroupPropertyMap<K,V>

Type Parameters:

K - Property key

V - Property value

All Implemented Interfaces:

Serializable, Cloneable, Map<K,V>

public class DefaultGroupPropertyMap<K,V>
extends HashMap<K,V>

Default implementation of a writable Map to manage group properties. Updates made to the elements in this map will also be applied to the database. Note this implementation assumes group property changes will be relatively infrequent and therefore does not try to optimize database I/O for performance. Each call to a Map mutator method (direct or indirect via Iterator) will result in a corresponding synchronous update to the database.

public DefaultGroupPropertyMap(Group group)

Group properties map constructor; requires associated Group instance

Parameters:

put

public V put(K key,
             V value,

Parameters:

key - The property name

value - The property value

persist - True if the changes should be persisted to the database

Returns:

The original value or null if the property did not exist
