extends java.lang.Object

The Factory interface define contants used by the element factories. In general, these contants indicate when elements are created, cached, and uncached. In addition this class provides support for notifying observers of a factory when object are created, cached, and uncached.

Method Detail

attach

public static void attach(Observer observer,
                          java.lang.Class clazz)

Associates the specified observer with the given clazz. Every time an instance of clazz is cached in the node factory, a NODE_CACHED notification is broadcast to the observer. The clazz should be the class of node and not of the data. The reason for this is that calling Node.getData() may break lazy loading for some nodes.

detach

public static void detach(Observer observer,
                          java.lang.Class clazz)

Removes the specified observer from the given clazz list of observers.

notify

protected static void notify(Element element,
                             int msgID)
