Description
QueryAdjacentEdges returns an array of adjacent edges, their weights, and their orientation. The array has adjacentEdgesCount entries, where adjacentEdgesCount is the value returned by FindAdjacent.

Remarks
adjacentEdgeEIDs, ReverseOrientation, and adjacentEdgesWeightValue 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.
Values in the ReverseOrientation array are TRUE if the edge "enters" the junction. That is, the junction specified in FindAdjacent is the "to-junction" of the returned edge. ReverseOrientation values will be FALSE if the edge "leaves" the junction - it is the "from-junction" of the returned edge.
