Class IlvNullActivity

java.lang.Object

ilog.views.gantt.model.IlvAbstractActivity

ilog.views.gantt.model.IlvSimpleActivity

ilog.views.gantt.model.IlvNullActivity

All Implemented Interfaces:

IlvActivity, IlvHierarchyNode, Serializable

public final class IlvNullActivity
extends IlvSimpleActivity

IlvNullActivity is a special implementation of the IlvActivity interface that is used as the root activity of a Gantt data model when a root has not been explicitly specified. For example:

• When 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.

Since:

JViews 6.0
