Class UMLElementSelectionService

java.lang.Object

RMPElementSelectionService

com.ibm.xtools.uml.ui.elementselection.UMLElementSelectionService

public class UMLElementSelectionService
extends RMPElementSelectionService

A specialization of GMF's element selection service, that provides support for querying transactional editing domains on multiple background jobs while a thread that has a read or read/write transaction on an editing domain is showing an element selection dialog.

The singleton instance of this class should be used as an alternative to the ElementSelectionService singleton wherever a transactional editing domain is to be queried.
