The NetworkAncillaryRole property will return the esriNetworkAncillaryRole enumeration which indicates if the junction class has a network ancillary role. Since junctions in a geometric network can act as a source, a sink or neither when calculating flow direction, this property will indicate whether or not the features in the class can be sources or sinks. If the class is a simple edge or complex edge network class, the ancillary role will always be returned as esriNCARNone since only junctions may have ancillary roles.
