ITraceFlowSolverGEN.FindFlowUnreachedElements Method

Finds all unreachable network elements based on the flow method.

[Visual Basic .NET]
Public Sub FindFlowUnreachedElements ( _
    ByVal flowMethod As esriFlowMethod, _
    ByVal flowElements As esriFlowElements, _
    ByRef junctionEIDs As IEnumNetEID, _
    ByRef edgeEIDs As IEnumNetEID _
)
[C#]
public void FindFlowUnreachedElements (
    esriFlowMethod flowMethod,
    esriFlowElements flowElements,
    ref IEnumNetEID junctionEIDs,
    ref IEnumNetEID edgeEIDs
);
[C++]
HRESULT FindFlowUnreachedElements(
  esriFlowMethod flowMethod,
  esriFlowElements flowElements,
  IEnumNetEID** junctionEIDs,
  IEnumNetEID** edgeEIDs
);
[C++]
Parameters
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**

Product Availability

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

Remarks

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.
