ArcObjects Library Reference (NetworkAnalysis)

INetElementBarriersGEN Interface

Provides access to members that specify a set of barriers by EIDs for the TraceFlowSolver object.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

When To Use

Use the INetElementBarriersGEN interface to create a set of barriers to pass to the TraceFlowSolver object.

Barriers are stopping points affecting a trace. For example, a downed powerline can be a barrier that affects a trace. Barriers do not affect the flow through a network. If you want to change the flow through a stand-alone logical network you can disable individual elements using the INetAttributesEdit::SetDisabledState method. For geometric networks, set the INetworkFeature::Enabled property to False.
