Class CompletedChangeCommand

java.lang.Object

org.eclipse.emf.common.command.AbstractCommand

com.corticon.eclipse.core.util.CompletedChangeCommand

All Implemented Interfaces:

org.eclipse.emf.common.command.Command

public class CompletedChangeCommand
extends org.eclipse.emf.common.command.AbstractCommand

CompletedChangeCommand is a type of command that is used with the ChangeRecorder. When the ChangeRecorder is used, EMF state changes are done directly as opposed to being deferred to the command stack. When a set of recorded changes is completed an instance of this object is added to the stack exclusively for undo/redo. Thus, the execute command for this class is non-operational, since the changes have already been accomplished.
