Parameters

GeometricNetwork

An IGeometricNetwork object that specifies the network model on which the tracing is to be performed.

settings

An IMMElectricTraceSettings object that specifies some interpretation policies to be applied to the network's elements.

currentStatus

Optional. An IMMCurrentStatus object that instructs the trace how to behave when it encounters a junction or edge while tracing. If your tracing application is straightforward and uses a normal switch status as reflected in the MMElectricTraceWeight value of each junction and edge feature, you can supply null (C#) or Nothing (VB) for this parameter.

startEID

A long integer that specifies the starting point of the trace. This is the Esri Network Element ID of the start element (a 32-bit integer).

startElementType

A value from the esriElementType enumeration that indicates whether the startEID value is the ID of a junction or an edge.

Phases

A value from the SetOfPhases enumeration that indicates the phase of the encountered edge or junction.

directionInfo

A value from the mmDirectionInfo enumeration. This value, used in conjuction with the startEID and startElementType (or upstreamNeighborEID and upstreamNeighborElementType) values, determines the direction of the trace.

upstreamNeighborEID

A long integer that specifies the next upstream element from the start of the trace. This is the Esri Network Element ID of the upstream element (a 32-bit integer).

upstreamNeighborElementType

A value from the esriElementType enumeration that indicates whether the upstreamNeighborEID value is the ID of a junction or an edge.

barrierJunctions

Specifies the ID of a junction (as Variant) that constitutes a barrier to all electrical phases; when the trace encounters a barrier element, it must terminate the path at that point.

barrierEdges

Specifies the ID of an edge (as Variant) that constitutes a barrier to all electrical phases; when the trace encounters a barrier element, it must terminate the path at that point.

excludeOpenDevices

This boolean argument can be used to include or exclude any junctions that were reached by the trace, but whose status stopped the trace from continuing beyond the junction (no phases continued through the junction). True = exclude open devices; False = include open devices

tracedJunctions

Returns IMMTracedElements, a collection of individual IMMTracedElement objects for junctions encountered during the trace.

tracedEdges

Returns IMMTracedElements, a collection of individual IMMTracedElement objects for edge encountered during the trace.
