Remarks

The FindFlowEndElements method returns those network elements stopping the trace. Network elements stopping a trace are those elements past which a trace cannot continue. These include network elements in a disabled element class (specified by INetSolver::DisableElementClass), and network elements that are connected to only one other network element.

The FlowMethod parameter determines whether the trace solver traces upstream, downstream, or on all connected edges.  If you would like to allow or restrict tracing on edges with indeterminate or uninitialized flow, be sure to set the TraceIndeterminateFlow property prior to calling this trace solver.

The flowElements parameter determines whether edge elements, junction elements, or both are returned by the trace solver.

The trace solver will return the traced junction and edge element IDs in the junctionEIDs and edgeEIDs parameters respectively.
