ArcObjects Library Reference (GeoDatabase)

INetTopologyEdit Interface

Provides access to members that add and delete network elements from the logical network.

Product Availability

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

When To Use

Use the INetTopologyEdit interface to add and delete elements from a logical network.

This interface is designed specifically for the editing of a stand-alone logical network, a logical network that does not have an associated geometric network. It is imperative that if you have a geometric network, the logical network must be edited through its associated geometric network. You risk data corruption if you use the INetTopologyEdit interface on logical networks that have an associated geometric network. When a feature is created or removed in the geometric network, the corresponding element in the logical network is added or deleted as well.

The logical network maintains its own topology for the purpose of faster access. Directly manipulating the logical network's topology will cause the features in the geometric network to be out of sync with the topology maintained by the logical network.
