Synthèse
The following properties are supported by the networkAttributes object in a utility network.
Propriétés
Propriété | Explication | Type de données |
assignments (Lecture seule) | The assignments object. This object can be used to retrieve properties of the network attribute assignments. | Object |
bitPosition (Lecture seule) | The bit position value of the network attribute. | Integer |
bitSize (Lecture seule) | The bit size value of the network attribute. | Integer |
creationTime (Lecture seule) | The creation date and time for the network attribute. | DateTime |
dataType (Lecture seule) | The data type of the network attribute—for example, integer or double. | String |
edgeWeightID (Lecture seule) | The edge weight ID value of the network attribute. | Integer |
fieldType (Lecture seule) | The data type of the of the network attribute field—for example, short or long integer, double, or date. | String |
isApportionable (Lecture seule) | A Boolean value describing whether the network attribute is apportionable.
| Boolean |
ID (Lecture seule) | The ID of the network attribute. | Integer |
isEmbedded (Lecture seule) | A Boolean value describing whether the network attribute is embedded.
| Boolean |
isNullable (Lecture seule) | A Boolean value describing whether the network attribute is nullable (allows null values).
| Boolean |
isOverridable (Lecture seule) | A Boolean value describing whether the network attribute can be overridden.
| Boolean |
isSubstitution (Lecture seule) | A Boolean value describing whether the network attribute is for substitution.
| Boolean |
junctionWeightID (Lecture seule) | The junction weight ID value of the network attribute. | Integer |
name (Lecture seule) | The name of the network attribute. | String |
networkAttributeToSubstitute (Lecture seule) | The value used for attribute substitution. Learn more about advanced network attributes and attribute substitution. | String |
usageType (Lecture seule) | The usage type of the network attribute—for example, terminal ID, source ID, and asset group. | String |
