    ByVal Edge As INetworkEdge, _
    ByVal fromPosition As Double, _
    ByVal toPosition As Double, _
    ByVal Attribute As INetworkAttribute, _
    ByVal adjustmentType As esriNetworkAttributeAdjustmentType, _
    ByVal Value As Object _
)

[C#]
public void AdjustEdgeAttributeValue (
    INetworkEdge Edge,
    double fromPosition,
    double toPosition,
    INetworkAttribute Attribute,
    esriNetworkAttributeAdjustmentType adjustmentType,
    object Value
);

[C++]
HRESULT AdjustEdgeAttributeValue(
  INetworkEdge* Edge,
  double fromPosition,
  double toPosition,
  INetworkAttribute* Attribute,
  esriNetworkAttributeAdjustmentType adjustmentType,
  VARIANT Value
);

Remarks

AdjustEdgeAttributeValue applies attribute adjustments along a given range for the input edge. Multiple, disjoint partial-edge attribute adjustments may be applied to the same edge. The RemoveAttributeAdjustments method can be used for removing all element-specific attribute adjustments.

Attribute adjustments at the NetworkForwardStar level allow dynamically adjusting network attribute values at runtime. For example, it is possible to add a constant value to a cost attribute or scale a cost attribute by a constant factor, as well as dynamically replacing attribute values.

Please see the help for esriNetworkAttributeAdjustmentType for attribute adjustment usage protocols, including rules for overlapping attribute adjustments along an edge.
