IExtensionStatus |
getStatus()
Gets the status of the extension, which may be queried to check

|
void |
update(Observable observable,
Object notification)
Called whenever a
Observable object is changed and this
Observer has registered on it to receive notifications. |
public void execute(String actionCommand)
IExtensionexecute in interface IExtensionactionCommand - An String specifying the action to
execute. This is useful when there are different
controls associated with the same extension.public void initialize()

ObserverObservable object is changed and this
Observer has registered on it to receive notifications.
Implementations of this method will be called for each simple notification or, if a complex notification is created, for each of the child notifications.
In the latter case, don't assume any ordering in the notification between
this Observer and other Observers listening to the same
Observable.
In a complex notification scenario, if you want to receive only the
complex notification and not each of the child notifications, just
implement the ComplexObserver and prepare this method
implementation to handle receiving DefaultComplexNotification instances
as well as direct notification objects.
