CoClasses that implement IJunctionFeatureSource
| CoClasses and Classes | Description |
|---|---|
| JunctionFeatureSource | A container for describing a network dataset source whose junction elements are derived from point feature geometry. |
Remarks
The IJunctionFeatureSource interface is used to access the properties of the junction feature source, such as its connectivity groups and elevation field name.
To access the JunctionFeatureSource object for an existing network dataset source, use the Source, SourceByID, or SourceByName methods on the INetworkDataset interface.
The IJunctionFeatureSource interface is also used to define a new junction feature source. To create a new junction feature source, cocreate the JunctionFeatureSource object, specify its properties on both the INetworkSource and IJunctionFeatureSource interfaces, and pass the object to the INetworkBuild::AddSource method on the network dataset.
