UtilityNetwork

Summary

The UtilityNetwork class provides access to methods that support managing subnetwork controllers and associations between network features.

Syntax

UtilityNetwork(utilityNetworkPath)

Name Explanation Data type

utilityNetworkPath

The input utility network.

String

Methods

AddConnectivityAssociation(association_type, from_table, from_global_id, from_terminal_name, to_table, to_global_id, to_terminal_name, percent_along)

The AddConnectivityAssociation method creates a connectivity association between two noncoincident features to model connectivity.

For example, you can define connectivity associations for point feature classes and junction object tables in the domain network as long as network rules exist to support the association.

There are several types of connectivity associations: Junction-junction connectivity, Junction-edge from connectivity, Junction-edge midspan connectivity, and Junction-edge to connectivity.

Name Explanation Data type

association_type

An integer value representing the type of connectivity association that will be created.

  • 1—Junction-Junction Connectivity association

  • 4—Junction-Edge From Connectivity association

  • 5—Junction-Edge Midspan Connectivity association

  • 6—Junction-Edge To Connectivity association

Integer

from_table

The table name of the from object.

String

from_global_id

The global ID of the from object.

String

from_terminal_name

The terminal name of the from object.

String

The table name of the to object.

String

to_global_id

The global ID of the to object.

String

to_terminal_name

The terminal name of the to object.

String

percent_along

The percentage along the edge where the connection occurs. This is only used for midspan connectivity..

Float

Return value

Data type Explanation

Integer

The object ID of the new connectivity association.

AddContainmentAssociation(container_table, container_global_id, content_table, content_global_id, is_content_visible)

The AddContainmentAssociation method creates a containment association to model a dense collection of features in a network.

Containment associations allow a collection of features to be represented by a single feature. For example, devices, wires, and conductors can be placed inside features such as substations, switch gears, trenches, and ducts. Content features can be shown or hidden in the map view to improve visibility and reduce map clutter. Features that contain other features are known as containers and the features being contained are known as content.

A utility network supports nested containment as well as a one-to-many relationship between content and containers. With nested containment, a container feature can contain another container feature, which in turn contains other content. For example, a substation can contain a junction box, and the junction box can contain electrical devices. In a one-to-many relationship, a single content feature is contained in more than one container, for example, a single underground line spanning many duct banks.

Note:

A point feature cannot be content in more than one container feature.

Name Explanation Data type

container_table

The table name of the container object.

String

container_global_id

The global ID of the container object.

String

content_table

The table name of the content object.

String

content_global_id

The global ID of the content object.

String

is_content_visible

Specifies whether the content will be visible.

Boolean

if editor.isEditing:
    editor.stopOperation()
    editor.stopEditing(True)

AddStructuralAttachmentAssociation(structure_table, structure_global_id, attachment_table, attachment_global_id)

The AddStructuralAttachmentAssociation method creates a structural attachment association to allow the modeling of supporting structures and attachments that convey resources in the network.

Structural attachments logically associate structure features with other features in a utility network. These associations allow modeling the relationship between structures that support equipment and associated assets that are attached. For example, a pole can serve as the structure, with a transformer as the attachment.
