Class UndoableCommand

  • public abstract class UndoableCommand
extends Object
    An action that can be rolled back. Similar to an UndoableEdit, but assumes that the action is yet to be executed, whereas an UndoableEdit assumes that the action has already been executed (i.e. it has a #redo method but not a #do method).
