Interface VUObjectListener

All Superinterfaces:

EventListener

public interface VUObjectListener
extends EventListener

This class can be used to create a object that watches which changes appear related to objects.

Beside the possibility to retrieve objects that are available within a defined area this class can be used to notice if an object was built completely new too.
Please note: there is no constant for a changed object. If an object was modified somehow, it is noticed as new. Within the appropriate VUObjectInfo object the ID of the old object can befound to identify this one as changed. Please also refer to VUObjectInfoTool
