Public Methods

Method Description
GetResourceDictionariesWhere ( bool>.Func predicate ) : IEnumerator

Returns a rotating enumerator of ResourceDictionary objects that coordinates with the dispenser object to ensure that no two enumerators are on the same item. If the dispenser is reset or its collection is changed then the enumerators are also reset.
GlobalSeriesIndexChanged ( int globalIndex ) : void

This method updates the global series index property.
PieSeries ( ) : System

Initializes a new instance of the PieSeries class.
