Interfaces Description
ISelectionSetBarriers Provides access to members that specify a set of barriers for the TraceFlowSolver object.


A SelectionSetBarriers object is used to specify selection set barriers for the TraceFlowSolver object. Because SelectionSetBarriers objects are co-creatable, you can use this class to specify barriers using code. Alternatively, by calling INetworkAnalysisExtBarriers::CreateSelectionBarriers, you can create a SelectionSetBarriers object based on the selected features and the SelectionSemantics property on the Utility Network Analysis extension.
