Remarks

The AddRestrictionAttribute method adds a NetworkAttribute to the NetworkForwardStar object. This prevents network elements that have a value of True for this attribute from being returned by the forward star in QueryAdjacencies. This is useful when performing a network analysis only on those network elements that permit travel.

Only a NetworkAttribute with a UsageType of esriNAUTRestriction can be added to the NetworkForwardStar as a restriction.
