Class 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 PersistableMap<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.
