Remarks

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.

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.
