Method Detail

finalize

public void finalize()

Overrides:

finalize in class Object

add

public void add(Viewpoint contents)

Description copied from interface: ProxyObserver

Subscribed items are broken apart and fed one by one to these methods. Replacement after an event is done by feeding the new memberbase with the same id. ID could be an XPath?

Specified by:

add in interface ProxyObserver<Viewpoint>

remove

public void remove(String oldId)

Description copied from interface: ProxyObserver

the 'type' parameter should be an indication of the type of object supplied so that the subscriber can associate the call back with one of its subscriptions. If we go with an Xpath subscription form, then the id will probably be sufficient. Should be comparable (substring whatever) with the parameter given to the subscribe method of ItemProxy.

Specified by:

remove in interface ProxyObserver<Viewpoint>

toString

public String toString()

Overrides:

toString in class Object

control

public void control(String control,
                    String msg)

Specified by:

control in interface ProxyObserver<Viewpoint>
