Network Attributes properties

Zusammenfassung

The following properties are supported by the networkAttributes object in a utility network.

Eigenschaften

Eigenschaft	Erläuterung	Datentyp
assignments (Schreibgeschützt)	The assignments object. This object can be used to retrieve properties of the network attribute assignments.	Object
bitPosition (Schreibgeschützt)	The bit position value of the network attribute.	Integer
bitSize (Schreibgeschützt)	The bit size value of the network attribute.	Integer
creationTime (Schreibgeschützt)	The creation date and time for the network attribute.	DateTime
dataType (Schreibgeschützt)	The data type of the network attribute—for example, integer or double.	String
edgeWeightID (Schreibgeschützt)	The edge weight ID value of the network attribute.	Integer
fieldType (Schreibgeschützt)	The data type of the of the network attribute field—for example, short or long integer, double, or date.	String
isApportionable (Schreibgeschützt)	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 (Schreibgeschützt)	The ID of the network attribute.	Integer
isEmbedded (Schreibgeschützt)	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 (Schreibgeschützt)	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 (Schreibgeschützt)	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 (Schreibgeschützt)	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 (Schreibgeschützt)	The junction weight ID value of the network attribute.	Integer
name (Schreibgeschützt)	The name of the network attribute.	String
networkAttributeToSubstitute (Schreibgeschützt)	The value used for attribute substitution. Learn more about advanced network attributes and attribute substitution.	String
usageType (Schreibgeschützt)	The usage type of the network attribute—for example, terminal ID, source ID, and asset group.	String
