public final class IlvNullActivity extends IlvSimpleActivity

IlvGanttDocumentReader
reads a Gantt.NET XML file that does not have an explicit root activity
specified, it automatically sets an IlvNullActivity
as the
root of the data model.IlvGanttDocumentWriter
does not write out the root activity if it is an instance of
IlvNullActivity
.Constructor and Description |
