|---|---|
| NetworkDataset | A container for querying information about a network dataset. |
Remarks
The INetworkQuery interface is used to retrieve the elements of the network dataset. You can query for network elements by their element type, by the source that generated them, or by the Object IDs of their source features.
You can also query other elements that are immediately adjacent to given elements by using the NetworkForwardStar object. This object allows you to repeatedly query the adjacent elements and their attribute values efficiently.
