Propriétés
Propriété | Explication | Type de données |
name (Lecture seule) | The name of the feature class associated with this network source. | String |
sourceID (Lecture seule) | The unique identifier of this network source within the network dataset. | Integer |
sourceType (Lecture seule) |
The type of network source. This property returns the following keywords:
| String |
elementType (Lecture seule) |
Network element type of the network source. This property returns the following keywords:
| String |
connectivityPolicies (Lecture/écriture) | The network dataset junction Connectivity Policies object. This object can be used to determine connectivity information, such as connectivity policies and connectivity groups, used by the junction sources of the network dataset. | Object |
elevationFieldName (Lecture seule) | The field name in the feature class associated with the given junction feature source that is used as the elevation field when determining connectivity at coincident vertices. | String |
Exemple de code
Displays information for junction sources in the network dataset.
