Class UndoRedoActionGroup


  • public final class UndoRedoActionGroup
    extends ActionGroup

    UndoRedoActionGroup provides standard undo and redo action handlers for a workbench part site. It supports filtering of undo or redo on a particular undo context. The undo context can be optionally pruned, which means the context will be flushed actively whenever an invalid operation is found on top of its history. This class may be instantiated by clients.
