Index is a number between 0 and n-1, where n is the number of adjacent edges returned by FindAdjacent. AdjacentEdgeWeightValue is the value of the weight specified in the CreateForwardStar method of the INetwork interface.

ReverseOrientation is TRUE if the edge "enters" the junction. That is, the junction specified in FindAdjacent is the "to-junction" of the returned edge. ReverseOrientation will be FALSE if the edge "leaves" the junction - it is the "from-junction" of the returned edge. When ReverseOrientation is TRUE, the weight value returned will be the pToFromEdgeWeight specified in INetwork::CreateForwardStar method. When FALSE, the value is the pFromToEdgeWeight specified.
