public abstract class AbstractUndoRedoAction
extends AbstractJmodelAction

An abstract class grouping functionalities common to Undo and Redo action. These kind of action are a bit tricky because we want their displayed name to contain a description of the edit that will be redone. A way to do this is maintaining a list of all created instances and scanning through it at every update.
That said, the main function of this class is to provide a means to update the state of all Undo/redo actions through its static method updateAll()
