Raises the UndoRedoChanged event.
AnnAutomation.prototype.onUndoRedoChanged = function(
): void; // protected
Raising an event invokes the event handler through a delegate. The OnUndoRedoChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors: When overriding OnUndoRedoChanged in a derived class, be sure to call the base class's OnUndoRedoChanged method so that registered delegates receive the event.
The UndoRedoChanged event will be fired when the undo/redo buffer changes. This gives the application a chance to update the user interface if needed.
The undo/redo buffer changes whenever an object inside the Container changes either by user interaction through the user interface or by code.
