| StorageHandler | | public interface StorageHandler extends Handler(Code) | | Handler for storing Page Flow objects.
|
| allowBindingEvent | | public boolean allowBindingEvent(Object event)(Code) | | Tell whether a given binding event should be allowed to occur. This is mainly useful in cases when this
handler writes data to some underlying storage (like the HttpSession) at some time other than
when
StorageHandler.setAttribute is called, in which case a binding event would be misleading. Only
org.apache.beehive.netui.pageflow.PageFlowManagedObject s pay attention to this.
