Enclosing class:

IlvZoomToFitAction

public static class IlvZoomToFitAction.RootActivityIntervalPolicy
extends Object
implements IlvZoomToFitAction.IntervalPolicy

The RootActivityIntervalPolicy class determines the time interval of a Gantt data model from its root activity. This works well for instances of IlvSimpleActivity that have their setAutoCalcTimeIntervalFromChildren flag set to true. In this case, the root activity's interval will be the union of all its children.
