All Implemented Interfaces:

java.io.Serializable, javax.swing.undo.UndoableEdit

public class PlayPenComponentLocationEdit
extends javax.swing.undo.AbstractUndoableEdit

An undoable edit that absorbs PropertyChangeEdits from PlayPenComponents. The way it is used is to add it to the undo manager using UndoManager.addEdit(UndoableEdit) before any components start moving. Then as each successive PropertyChangeEdit is added to the undo manager, this edit will absorb it if it represents a change in location of a PlayPenComponent. As soon as any other type of edit is added to the undo manager, this edit will refuse to absorb it, and new edits will be accumulated by the undo manager as usual.
