Interface IEdgeFeature

All Superinterfaces:

Serializable

All Known Implementing Classes:

ComplexEdgeFeature, SimpleEdgeFeature

public interface IEdgeFeature
extends Serializable

Provides access to members that modify and return information about an edge feature.

Remarks

Use the IEdgeFeature interface to get information about an edge feature as well as to disconnect an edge feature from a geometric network. The IEdgeFeature interface should not be used as a means to traverse the network. IEdgeFeature should only be used to return the connectivity information for features connected to the specific edge feature. Using the IEdgeFeature interface to navigate through the network will be extremely slow and cumbersome. For traverses through the network use the IForwardStar interface on the Network Object Model.
