Class EditingChangeState

Object

charger.EditingChangeState

public class EditingChangeState
extends Object

Encapsulates the status of the change resulting from an editing operation. There are two kinds of content changes: appearance changes, where something has moved or changed color, and semantic changes, where something has altered the meaning (text label or nesting) of a graph. In addition, we want to separately note whether the change is to be undoable or not.
