INetworkClass.FieldToWeightMapping Property

The specified field to Weight mapping for the logical network.

[Visual Basic .NET]
Public Function get_FieldToWeightMapping ( _
    ByVal FieldIndex As Integer _
) As Integer

[C#]
public int get_FieldToWeightMapping (
    int FieldIndex
);

[C++]
HRESULT get_FieldToWeightMapping(
  long FieldIndex,
  long* WeightID
);

[C++]

Parameters
FieldIndex [in]
  FieldIndex is a parameter of type long
WeightID [out, retval]
  WeightID is a parameter of type long

Product Availability

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

Remarks

The FieldToWeightMapping property will return the index of the network weight to which a field in the network class is mapped in the logical network. You can then use the INetSchema::Weight property to return the INetWeight interface on that particular network weight. If the field has no weight associated with it, FieldToWeightMapping returns a -1.

[C#]

The following code prints the name of the weight assoiated with each field in a network class.

// Use the INetSchema interface to get network weights.
IGeometricNetwork geometricNetwork=networkClass.GeometricNetwork;
INetwork network=(INetwork)geometricNetwork.Network;
INetSchema netSchema=(INetSchema)network;

// For each field in the network class, print its weight associations.
IFields fields=networkClass.Fields;
for (int i=0; i < fields.FieldCount; i++)
{
 IField field=fields.get_Field(i);
 int weightIndex=networkClass.get_FieldToWeightMapping(i);
 if (weightIndex != -1)
 {
  INetWeight weight=netSchema.get_Weight(weightIndex);
  Console.WriteLine("{0} maps to {1}", field.Name, weight.WeightName);
 }
 else
 {
  Console.WriteLine("{0} maps to nothing", field.Name);
 }
}

[Visual Basic .NET]

The following code prints the name of the weight assoiated with each field in a network class.

' Use the INetSchema interface to get network weights.
Dim geometricNetwork As IGeometricNetwork=networkClass.GeometricNetwork
Dim network As INetwork=CType(geometricNetwork.Network, INetwork)
Dim netSchema As INetSchema=CType(network, INetSchema)

' For each field in the network class, print its weight associations.
Dim fields As IFields=networkClass.Fields
Dim i As Integer
For i=0 To fields.FieldCount - 1
 Dim field As IField=fields.Field(i)
 Dim weightIndex As Integer=networkClass.FieldToWeightMapping(i)
 If weightIndex <> -1 Then
  Dim weight As INetWeight=netSchema.Weight(weightIndex)
  Console.WriteLine("{0} maps to {1}", field.Name, weight.WeightName)
 Else
  Console.WriteLine("{0} maps to nothing", field.Name)
 End If
