listener - a ServiceBinderListener to add to the Architecture service

removeServiceBinderListener

public void removeServiceBinderListener(ServiceBinderListener listener)

Remove a service binder listener

Specified by:

removeServiceBinderListener in interface ArchitectureService

Parameters:

listener - the listener to be removed

fireInstanceChangeEvent

public void fireInstanceChangeEvent(InstanceChangeEvent evt)
