All Implemented Interfaces:
UndoableEdit

  • Method Details

    • undo

      public void undo() throws CannotUndoException
      Undo the edit that was made.
      Specified by:
      undo in interface UndoableEdit
      Throws:
      CannotUndoException

    • canUndo

      public boolean canUndo()
      True if it is still possible to undo this operation.
      Specified by:
      canUndo in interface UndoableEdit

    • redo

      public void redo() throws CannotRedoException
      Re-apply the edit, assuming that it has been undone.
      Specified by:
      redo in interface UndoableEdit
      Throws:
      CannotRedoException

    • canRedo

      public boolean canRedo()
      True if it is still possible to redo this operation.
      Specified by:
      canRedo in interface UndoableEdit

    • die

      public void die()
      May be sent to inform an edit that it should no longer be used. This is a useful hook for cleaning up state no longer needed once undoing or redoing is impossible--for example, deleting file resources used by objects that can no longer be undeleted. 
      UndoManager
      calls this before it dequeues edits. Note that this is a one-way operation. There is no "un-die" method.
