Relative to the last generation to let the generator optimize the recycling logic.

itemsExpectedToBeGenerated

An optional list of items are are expected to be generated. This is used to optimize eleme nt recycling.

Remarks

This method is usually called at the beginnning of a RecyclingItemsPanel derived class's MeasureOverride logic. This is normally followed by one or more StartAt(GeneratorPosition,GeneratorDirection,Boolean)%M:Infragistics.Windows.Virtualization.RecyclingItemContainerGenerator.GenerateNext(System.Boolean@)% loops to generate all 'active' containers. Finally, the EndGeneration method is called at the end of the measure logic.
