C++
virtual void modifyUndone( const AcDbObject* );
Description
This function is invoked when the object pointed to by dbObj has a modification undone. For example, setting a line object's endpoint and then executing the AutoCAD Undo command to undo the change would result in this notification being sent.
When an object is opened for write, it is modified via a method that calls assertWriteEnabled, and then its cancel method is called instead of its close method, then this notification will be sent as well as the modified notification.
This notification takes place when the object is closed after the undo or when its cancel method is invoked after making changes.
