IUtilityNetwork Interface

Provides access to members that get and set flow direction in a utility network. Note: the IUtilityNetwork interface has been superseded byIUtilityNetwork2. Please consider using the more recent version.

Product Availability

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

When To Use

Use the IUtilityNetwork interface for establishing flow direction for your network. You can also use this interface to check the flow direction for a particular element and change the flow direction on a particular element.

Members

	Name	Description
	CreateForwardStar	Creates a forward star cursor on the network index.
	CreateNetBrowser	Creates a network index element browser.
	EdgeCount	Number of edges in the network.
	EstablishFlowDirection	Sets the flow direction of all edge elements based on the placement of sources and sinks.
	GetFlowDirection	Returns the flow direction of the specified edge element.
	JunctionCount	Number of junctions in the network.
	MaxDegree	Maximum degree of a junction.
	MaxTurn	Maximum number of turns associated with a junction.
	SetFlowDirection	Sets the flow direction for the specified edge element.
	Status	Status of the network.
	TurnCount	Number of turns in the network.
	ValidFlowDirection	Indicates if the flow direction is valid for this utility network.

Inherited Interfaces

Interfaces	Description
INetwork	Provides access to members that give general information about the network and its elements.

Remarks

The only elements in a network that can have flow are edge elements. Junction elements do not have flow.

Flow is maintained in the logical network and not the geometric network. Unlike creating flags, which is done on a feature in the geometric network, changing flow direction on individual elements requires that you directly manipulate the logical network.

This operation requires that you make the network editable. You can do this either through an edit session, using the Editor, or you can use the IWorkspaceEdit interface to edit the workspace of the logical network.

[C#]

Not all members are callable from C#. Please use IUtilityNetworkGEN instead.

[Visual Basic .NET]

Not all members are callable from VB.NET. Please use IUtilityNetworkGEN instead.
