INetworkForwardStarEx.AddEdgeRestriction Method

Restricts the traversability of a range on an edge element in the adjacency queries.

[Visual Basic .NET]
Public Sub AddEdgeRestriction ( _
    ByVal Edge As INetworkEdge, _
    ByVal fromPosition As Double, _
    ByVal toPosition As Double _
)
[C#]
public void AddEdgeRestriction (
    INetworkEdge Edge,
    double fromPosition,
    double toPosition
);
[C++]
HRESULT AddEdgeRestriction(
  INetworkEdge* Edge,
  double fromPosition,
  double toPosition
);
[C++]

Parameters

Edge [in]

  Edge is a parameter of type INetworkEdge

fromPosition [in]   fromPosition is a parameter of type double toPosition [in]   toPosition is a parameter of type double

Product Availability

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

Remarks

AddEdgeRestriction restricts a given range for the input edge. Multiple, disjoint partial-edge restrictions may be applied to the same edge. The RemoveElementRestrictions method can be used for removing all element-specific restrictions.

If the traversal cannot enter the edge from the atJunction of a QueryAdjacencies call due to partial (or whole) edge restrictions, then the edge will not be included in the NetworkForwardStarAdjacencies object.

AddJunctionRestriction, AddEdgeRestriction, and AddTurnRestriction are intended as a replacement to INetworkForwardStarSetup::Traversable, as well as the related INetworkForwardStar::SetAllTraversable, INetworkForwardStarSetup::SetTraversable, and INetworkForwardStarSetup::NonTraversableElements.
