Creates a new UndoEngine.UndoUnit.
Assembly: System.Design (in System.Design.dll)
- Type: System.String
The name of the unit to create.
- Type: System.Boolean
true to create the first of a series of nested units; false to create subsequent nested units.
The default implementation of the 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.
