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

Description

QueryAdjacentJunctions returns an array of adjacent junctions and their weights. The array has adjacentEdgesCount entries, where adjacentEdgesCount is the value returned by FindAdjacent.

See also the QueryAdjacentJunction request.

Remarks

adjacentJunctionEIDs and adjacentJunctionsWeightValue are arrays that are dimensioned to at least adjacentEdgesCount, as returned by FindAdjacent. Note that the MaxDegree property of INetwork will tell you the maximum number of edges for any junction, and you can use this to allocate memory for these arrays. Count is equal to adjacentEdgesCount from FindAdjacent.

AdjacentJunctionsWeightValue contain weight values specified in the CreateForwardStar method of the INetwork interface.

[C#]
