Network Attributes properties

Résumé

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
