ArcObjects Library Reference (EditorExt)

UtilityNetworkAnalysisExt CoClass

A container for defining the Utility Network Analysis extension and describing its current state.

Product Availability

Available with ArcGIS Desktop.

Description

The UtilityNetworkAnalysisExt object provides functionality for analyzing utility networks in ArcMap. In order to use the UtilityNetworkAnalysisExt object, you must have an active ArcMap application, and obtain a reference to the extension object from the ArcMap application.

Supported Platforms

Windows

Extended Error Information

Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.
