Provides access to members that specify the properties of an attribute in a network dataset.

Members

	Name	Description
	DataType	Type of data used in this network attribute.
	ID	Unique identifier of this network attribute.
	IsTimeAware	Indicates if the network attribute is time aware.
	Name	Name of this network attribute.
	Parameters	Array of parameters for this network attribute.
	Refresh	Refresh the network evaluators assigned to this network attribute.
	Units	Units of this network attribute.
	UsageType	Usage type of this network attribute.
	UseByDefault	Indicates if this network attribute is to be used by default.

INetworkAttribute.DataType Property

Type of data used in this network attribute.

Public Property DataType As esriNetworkAttributeDataType

public esriNetworkAttributeDataType DataType {get; set;}

Remarks

The DataType for the network attribute can be either Integer, Float, Double, or Boolean.

Depending on the UsageType for the network attribute, only certain DataTypes are allowed:

UsageType:	Allowed DataTypes:
esriNAUTCost	esriNADTInteger, esriNADTFloat, esriNADTDouble
esriNAUTDescriptor	esriNADTInteger, esriNADTFloat, esriNADTDouble, esriNADTBoolean
esriNAUTRestriction	esriNADTBoolean
esriNAUTHierarchy	esriNADTInteger

INetworkAttribute.ID Property

Unique identifier of this network attribute.

Public ReadOnly Property ID As Integer

public int ID {get;}

INetworkAttribute.IsTimeAware Property

Indicates if the network attribute is time aware.

Public Function get_IsTimeAware ( _
    ByVal ElementType As esriNetworkElementType _
) As Boolean

public bool get_IsTimeAware (
    esriNetworkElementType ElementType
);

INetworkAttribute.Name Property

Name of this network attribute.

Public Property Name As String

public string Name {get; set;}

INetworkAttribute.Parameters Property

Array of parameters for this network attribute.

Public Property Parameters As IArray

public IArray Parameters {get; set;}

INetworkAttribute.Refresh Method

Refresh the network evaluators assigned to this network attribute.

Public Sub Refresh ( _
)

public void Refresh (
);

INetworkAttribute.Units Property

Units of this network attribute.

Public Property Units As esriNetworkAttributeUnits

public esriNetworkAttributeUnits Units {get; set;}

Remarks

If the attribute is not measured in units of distance or time, specify the Units as esriNAUUnknown.

INetworkAttribute.UsageType Property

Usage type of this network attribute.

Public Property UsageType As esriNetworkAttributeUsageType

public esriNetworkAttributeUsageType UsageType {get; set;}

Remarks

The UsageType for the network attribute can be either Cost, Descriptor, Restriction, or Hierarchy.

Depending on the UsageType for the network attribute, only certain DataTypes are allowed:

UsageType:	Allowed DataTypes:
esriNAUTCost	esriNADTInteger, esriNADTFloat, esriNADTDouble
esriNAUTDescriptor	esriNADTInteger, esriNADTFloat, esriNADTDouble, esriNADTBoolean
esriNAUTRestriction	esriNADTBoolean
esriNAUTHierarchy	esriNADTInteger

INetworkAttribute.UseByDefault Property

Indicates if this network attribute is to be used by default.

Public Property UseByDefault As Boolean

public bool UseByDefault {get; set;}
