| EdgeFeatureSource | A container for describing a network dataset source whose edge elements are derived from line feature geometry. |
Remarks
The IEdgeFeatureSource interface is used to access the properties of the edge feature source, such as its connectivity groups and elevation field names.
To access the EdgeFeatureSource object for an existing network dataset source, use the Source, SourceByID, or SourceByName methods on the INetworkDataset interface.
The IEdgeFeatureSource interface is also used to define a new edge feature source. To create a new edge feature source, cocreate the EdgeFeatureSource object, specify its properties on both the INetworkSource and IEdgeFeatureSource interfaces, and pass the object to the INetworkBuild::AddSource method on the network dataset.
