Network Attributes properties

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. True—The network attribute is apportionable. False—The network attribute is not 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. True—The network attribute is embedded. False—The network attribute is not embedded.	Boolean
isNullable (Lecture seule)	A Boolean value describing whether the network attribute is nullable (allows null values). True—The network attribute is nullable. False—The network attribute does not allow null values.	Boolean
isOverridable (Lecture seule)	A Boolean value describing whether the network attribute can be overridden. True—The network attribute can be overridden. False—The network attribute cannot be overridden.	Boolean
isSubstitution (Lecture seule)	A Boolean value describing whether the network attribute is for substitution. True—The network attribute is for substitution. False—The network attribute is not 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
