INetworkForwardStarEx.AddRestrictionAttribute Method

Adds a restriction network attribute to the NetworkForwardStar object to filter elements from adjacency queries.

[Visual Basic .NET]
Public Sub AddRestrictionAttribute ( _
    ByVal Attribute As INetworkAttribute _
)

[C#]
public void AddRestrictionAttribute (
    INetworkAttribute Attribute
);

[C++]
HRESULT AddRestrictionAttribute(
  INetworkAttribute* Attribute
);

[C++]

Parameters
Attribute [in]

  Attribute is a parameter of type INetworkAttribute

Product Availability

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

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.
