flowMethod [in]

  flowMethod is a parameter of type esriFlowMethod

flowElements [in]

  flowElements is a parameter of type esriFlowElements

junctionEIDs [out]

  junctionEIDs is a parameter of type IEnumNetEID

edgeEIDs [out]

  edgeEIDs is a parameter of type IEnumNetEID

pTotalCost [out]   pTotalCost is a parameter of type VARIANT

Product Availability

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


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 ITraceFlowSolver::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, and will return the total cost of the traced elements in the pTotalCost parameter.
