Protected Overridable Function CreateUndoUnit (name As String, primary As Boolean) As UndoEngine.UndoUnit

Parameters

name: String

The name of the unit to create.

primary: Boolean

true to create the first of a series of nested units; false to create subsequent nested units.

Returns

UndoEngine.UndoUnit

A new UndoEngine.UndoUnit with a specified name.

Remarks

The default implementation of the CreateUndoUnit method simply returns a new UndoEngine.UndoUnit.

By default, UndoEngine does nothing with the primary parameter, but some implementations of undo, such as those involving the COM Microsoft.VisualStudio.OLE.Interop.IOleParentUndoUnit design pattern, may need to identify the difference between a primary unit and its children.
