Members

	Name	Description
	ClassConnectivityGroup	Connectivity group in which this edge feature source participates.
	ClassConnectivityPolicy	Policy determining how all edge elements in this source connect to each other.
	FromElevationFieldName	The field name on the feature source to be used as the from elevation field when determining connectivity at coincident end vertices.
	SubtypeConnectivityGroup	Connectivity group in which the specified subtype of this edge feature source participates.
	SubtypeConnectivityPolicy	Policy determining how the edge elements in the specified subtype of this source connect to each other.
	ToElevationFieldName	The field name on the feature source to be used as the to elevation field when determining connectivity at coincident end vertices.
	UsesSubtypes	Indicates if this edge feature source determines connectivity groups and policies by subtypes.

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.
