Description copied from interface: ITraceFlowSolverGEN

Indicates if directional traces include edges with indeterminate or uninitialized flow direction.

Remarks

The TraceIndeterminateFlow property affects the trace results of trace solvers whose FlowMethod parameter is esriFMUpstream or esriFMDownstream.

If the TraceIndeterminateFlow parameter is set to True, then the trace solver will not only trace on the aforementioned edges, but also on edges with indeterminate or uninitialized flow.

Set the TraceIndetermiateFlow property before calling any of the trace solvers.

Specified by:

Description copied from interface: ITraceFlowSolverGEN

Finds all reachable network end elements based on the specified flow method.

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.

Specified by:

findFlowEndElements in interface ITraceFlowSolverGEN

                     AutomationException

Description copied from interface: ITraceFlowSolverGEN

Finds a path between the specified origins in the network.

Remarks

The FlowMethod parameter determines whether the trace solver traces upstream, downstream, or on all connected edges.

The objFn parameter specifies the objective function of the trace solver. Depending on this parameter, the trace solver will either attempt to minimize the total cost of the path, or will attempt to minimize the maximum cost of any single element in the path.

The Count is the number of path segments to be returned by the trace solver. It is equivalent to one less than the number of flags being passed into the trace solver. The Count is also the size of the array passed into the segmentCosts parameter.

The origins you place on the network using PutEdgeOrigins or PutJunctionOrigins must be either all edge origins or all junction origins. You cannot find a path among a mixture of edge and junction origins.

The trace solver will return the traced junction and edge element IDs in the junctionEIDs and edgeEIDs parameters respectively, and will return the cost of each segment in the segmentCosts array.

The traced element IDs are returned in the order that they were traced.

findAccumulation

public void findAccumulation(int flowMethod,
                             int flowElements,
                             IEnumNetEID[] junctionEIDs,
                             IEnumNetEID[] edgeEIDs,
                             java.lang.Object[] pTotalCost)
                      throws java.io.IOException,
                             AutomationException

Description copied from interface: ITraceFlowSolverGEN

Finds the total cost of all reachable network elements based on the specified flow method.

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

Specified by:

findAccumulation in interface ITraceFlowSolverGEN

Parameters:

flowMethod - A com.esri.arcgis.networkanalysis.esriFlowMethod constant (in)

flowElements - A com.esri.arcgis.networkanalysis.esriFlowElements constant (in)

junctionEIDs - A reference to a com.esri.arcgis.geodatabase.IEnumNetEID (out: use single element array)

edgeEIDs - A reference to a com.esri.arcgis.geodatabase.IEnumNetEID (out: use single element array)

pTotalCost - A Variant (out: use single element array)

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

disableElementClass

public void disableElementClass(int classID)
                         throws java.io.IOException,
                                AutomationException

Description copied from interface: INetSolver

Sets an element class as disabled within this solver.

classID - The classID (in)

Throws:

AutomationException - If the ArcObject component throws an exception.

java.io.IOException - If there are interop problems.
