Members

	Name	Description
	AbbreviationsTableName	The abbreviatiations table name.
	AttributeMappings	The collection of directions attribute mapping.
	DefaultOutputLengthUnits	The default length units that will be used for reporting distances in directions.
	LengthAttributeName	The name of the network attribute to be used for reporting travel distances.
	ReferenceLandmarkSources	The array of reference landmark source names.
	RoadClassAttributeName	The name of the network attribute to be used for road classification.
	RoadSplitsTableName	The name of the table containing the road splits.
	SignpostFeatureClassName	The name of the feature class containing the signposts.
	SignpostStreetsTableName	The name of the indexed table of signpost street references.
	SupportsLocalizedStreetNames	The flag that indicates if network has street names translated in multiple languages.

INetworkDirections.AbbreviationsTableName Property

The abbreviatiations table name.

Public Property AbbreviationsTableName As String

public string AbbreviationsTableName {get; set;}

INetworkDirections.AttributeMappings Property

The collection of directions attribute mapping.

Public Property AttributeMappings As IArray

public IArray AttributeMappings {get; set;}

INetworkDirections.DefaultOutputLengthUnits Property

The default length units that will be used for reporting distances in directions.

Public Property DefaultOutputLengthUnits As esriNetworkAttributeUnits

public esriNetworkAttributeUnits DefaultOutputLengthUnits {get; set;}

Remarks

The DefaultOutputLengthUnits that will be used for generating directions. This property is required for Direction generation.

The valid values are: esriNAUMiles, esriNAUKilometers, esriNAUMeters, esriNAUYards, and esriNAUFeet from the esriNetworkAttributeUnits enumeration.

This value does not have to correspond to the units specified for the LengthAttributeName property.

INetworkDirections.LengthAttributeName Property

The name of the network attribute to be used for reporting travel distances.

Public Property LengthAttributeName As String

public string LengthAttributeName {get; set;}

Remarks

The LengthAttributeName property is the attribute that will be used for distance measurements. The attribute must have a units value from the esriNetworkAttributeUnits enumeration that corresponds to a distance measurement and must be a Cost attribute. This does not have to be same value as specified in the DefaultOutputLengthUnits property. This property is required for Direction generation.

INetworkDirections.ReferenceLandmarkSources Property

The array of reference landmark source names.

Public Property ReferenceLandmarkSources As IStringArray

public IStringArray ReferenceLandmarkSources {get; set;}

INetworkDirections.RoadClassAttributeName Property

The name of the network attribute to be used for road classification.

Public Property RoadClassAttributeName As String

public string RoadClassAttributeName {get; set;}

Remarks

The RoadClassAttributeName property is the attribute that will be used for identifying different classes of roads in direction generation. The attribute must be of usage type: esriNAUTDescriptor and of data type: esriNADTInteger.

INetworkDirections.RoadSplitsTableName Property

The name of the table containing the road splits.

Public Property RoadSplitsTableName As String

public string RoadSplitsTableName {get; set;}

INetworkDirections.SignpostFeatureClassName Property

The name of the feature class containing the signposts.

Public Property SignpostFeatureClassName As String

public string SignpostFeatureClassName {get; set;}

INetworkDirections.SignpostStreetsTableName Property

The name of the indexed table of signpost street references.

Public Property SignpostStreetsTableName As String

public string SignpostStreetsTableName {get; set;}

INetworkDirections.SupportsLocalizedStreetNames Property

The flag that indicates if network has street names translated in multiple languages.

Public Property SupportsLocalizedStreetNames As Boolean

public bool SupportsLocalizedStreetNames {get; set;}

INetworkDirections.TimeAttributeName Property

The name of the network attribute to be used for reporting travel time.

Public Property TimeAttributeName As String

public string TimeAttributeName {get; set;}

Remarks

The TimeAttributeName property is the attribute that will be used for time measurements. The attribute must have a units value from the esriNetworkAttributeUnits enumeration that corresponds to a unit of time and must be a Cost attribute.

Classes that implement INetworkDirections

Classes	Description
NetworkDirections	A container for describing and using network directions.

Remarks

The INetworkDirections interface should be used to get and set Directions information at the network dataset level, such as the output length units or length attribute to be used for Directions generation. In order to generate directions a network dataset needs certain information which includes:

• Length attribute
• Length units
• At least one edge feature class with a primary name

The length attribute and units parameters are set on the INetworkDirections interface.
