Synthèse
The UtilityNetwork class provides access to methods that support managing subnetwork controllers and associations between network features. You can also create or delete connectivity, containment, and structural attachment associations between specified features, or enable or disable the subnetwork controller assignment from specified features.

Vue d’ensemble des méthodes
| Méthode | Explication |
| 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 and structure network as long as network rules exist to support the association. Two point features, such as a transformer and a fuse, that are not coincident can be offset from each other by x and y, or z while connectivity is maintained through a connectivity association. Junction-junction connectivity associations also support connectivity between terminals on features. There are several types of connectivity associations: Junction-junction connectivity, Junction-edge from connectivity, Junction-edge midspan connectivity, and Junction-edge to connectivity. |
| 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 dense 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. |
| 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. Learn more about how to create a structural attachment association |
| DeleteConnectivityAssociation (association_type, association_global_id) | The DeleteConnectivityAssociation method removes the connectivity association between two features. |
| DeleteContainmentAssociation (association_global_id) | The DeleteContainmentAssociation method removes the containment association between a container feature and its content. |
| DeleteStructualAttachmentAssociation (association_global_id) | The DeleteStructualAttachmentAssociation method removes the structural attachment association between a structure feature and an attachment feature. Learn more about how to delete a structural attachment association |
| DisableSubnetworkController (table, global_id, terminal_name) | The DisableSubnetworkController method removes the subnetwork controller assignment from a terminal on a device or junction object. |
| EnableSubnetworkController (table, global_id, terminal_name, subnetwork_controller_name, subnetwork_name, tier_name, description, notes) | The EnableSubnetworkController method enables a subnetwork controller. Subnetwork controllers are set on the terminal of a device or junction object to represent the origin of a subnetwork. |
| HasValidNetworkTopology () | The HasValidNetworkTopology method checks whether the network topology is enabled. Ensuring that the utility network's topology is enabled is helpful before creating associations and modifying subnetwork controllers. |
