public UndoManager(PlayPen playPen)
            throws ArchitectException

Creates a new UndoManager and attaches it to the given PlayPen's component and SQL Object model events.

Method Detail

addEdit

public boolean addEdit(javax.swing.undo.UndoableEdit anEdit)

Adds then given edit to this undo manager.

Warning: Edits added here do not respect compounding. You can add a whole CompoundEdit here, but if the current state of the undo manager is that it's in a compound edit, it doesn't matter. You will get individual edits when you add individual edits.
