Interface UndoRedoManager

public interface UndoRedoManager

This interface is used to record changes triggered by a user in the screen of a URCap program node contribution (e.g. when a button is clicked). It should be used in a URCap program node to support the Undo/Redo functionality in PolyScope. Do not use this functionality for URCap installation nodes, since it is not supported (and has no effect).

NOTE: This functionality is not relevant for URCap program nodes with a HTML-based user interface, since automatic undo is supported for these.
