ITurnFeatureSource Interface

Provides access to an indicator interface for a network dataset source whose turn elements are derived from a turn feature class.

Classes that implement ITurnFeatureSource

Classes Description
TurnFeatureSource A container for describing a network dataset source whose elements are derived from turn feature geometry.


The ITurnFeatureSource interface is used to identify the class as a TurnFeatureSource object.

To access the TurnFeatureSource object for an existing network dataset source, use the Source, SourceByID, or SourceByName methods on the INetworkDataset interface.

To create a new turn feature source, cocreate the TurnFeatureSource object, specify its properties on the INetworkSource interface, and pass the object to the INetworkBuild::AddSource method on the network dataset.
