Interface VwmInterface

All Superinterfaces:

MMBaseObserver

All Known Subinterfaces:

VwmServiceInterface

All Known Implementing Classes:

Vwm

public interface VwmInterface

extends MMBaseObserver

Virtual Web Master interface. A VWM should implement this interface. The routines defined here are entry routines for initializing a VWM, associating listeners (clients) with the VWM, and managing changes in local and remote nodes. Note: This interface defines a few methods also defined by the MMBaseObserver interface. Maybe it should extend it?

init

public void init(MMObjectNode node,
                 Vwms Vwms)
