Set Association Role (Utility Network)

Summary

Alters the association role assigned to a network feature class or table at the asset type level.

Association roles define how certain network features participate in a utility network. A utility network has existing system-provided association roles for structures and containers. For a network feature to be set as a container or structure using associations, it is necessary to first set an association role. This is assigned at the feature class or table level for specific asset groups and asset types.

Usage

• The view scale and deletion semantics for an asset type's role can be defined or updated with this tool.

• The network topology must be disabled.

• Unassigning container or structure association roles can only be done before the network topology is enabled for the first time. See Utility network management tasks for additional examples and their required network topology state.

• When working with an enterprise geodatabase, the connected ArcGIS Enterprise portal account must be the portal utility network owner.

• When working with an enterprise geodatabase, the Input Utility Network must be from a database connection established as the database utility network owner.

Parameters

Dialog

Label	Explanation	Data Type
Input Utility Network	The utility network that contains the asset type with an association role to set.	Utility Network; Utility Network Layer
Domain Network	The domain network that contains the asset type with an association role to set.	String
Input Table	The utility network feature class or table where the association role will be set.	String
Asset Group	The asset group that contains the asset type.	String
Asset Type	The asset type that the association role will be set for.	String
Role Type	Specifies the type of association role to assign to the asset type. Container —Features or objects of this asset type can contain other features and objects as content. Structure —Features or objects of this asset type can have other features and objects attached to them. None —No role type will be assigned. These are features or objects that are neither a container nor a structure but do connect to other structures.	String
Deletion Semantics	Specifies the deletion semantics for the features, which is how child features will be handled when the parent feature is deleted. This applies to both container and structure association roles. Cascade —When the parent container or structure is deleted, all content or attachment network features will be deleted. Set to none — When a container or structure is deleted, its content or attachment features and objects will not be deleted. Instead, it will be removed from the containment or structural attachment association. Restricted — If content or attachment features or objects exist, an error will be returned when attempting to delete the container or structure. The content or attachment features and objects must be removed before deleting the container or structure.	String
View Scale (Optional)	The scale at which containment mode will be entered to edit features participating in the container. For example, setting the view scale to 5 means that when you enter containment mode of the container feature, the scale will be 1:5. Units are based on the utility network units, which are located on the Source tab of the utility network layer properties pane. This property does not apply to junction and edge objects.	Double
Split Content (Optional)	Specifies whether the associated content of a container will be split if the container feature is split. This parameter is only available if the association role is container and is only applicable for line features. Checked—he container's content will be split if the container feature is split. If a parallel content line feature is found, the content is also split and each section will be contained by the closest container feature. If the content line is not parallel, the content will be contained by the container feature that is closest to it. Unchecked—The container's content will not be split if the container feature is split. If a parallel content line feature is found, the content will be contained by both sections of the container feature. If the content line is not parallel, the content will be contained by the container feature that is closest to it. This is the default.	Boolean

Name	Explanation	Data Type
in_utility_network	The utility network that contains the asset type with an association role to set.	Utility Network; Utility Network Layer
domain_network	The domain network that contains the asset type with an association role to set.	String
featureclass	The utility network feature class or table where the association role will be set.	String
assetgroup	The asset group that contains the asset type.	String
assettype	The asset type that the association role will be set for.	String
association_role_type	Specifies the type of association role to assign to the asset type. CONTAINER —Features or objects of this asset type can contain other features and objects as content. STRUCTURE —Features or objects of this asset type can have other features and objects attached to them. NONE —No role type will be assigned. These are features or objects that are neither a container nor a structure but do connect to other structures.	String
association_deletion_semantics	Specifies the deletion semantics for the features, which is how child features will be handled when the parent feature is deleted. This applies to both container and structure association roles. CASCADE —When the parent container or structure is deleted, all content or attachment network features will be deleted. SET_TO_NONE — When a container or structure is deleted, its content or attachment features and objects will not be deleted. Instead, it will be removed from the containment or structural attachment association. RESTRICTED — If content or attachment features or objects exist, an error will be returned when attempting to delete the container or structure. The content or attachment features and objects must be removed before deleting the container or structure.	String
view_scale (Optional)	The scale at which containment mode will be entered to edit features participating in the container. For example, setting the view scale to 5 means that when you enter containment mode of the container feature, the scale will be 1:5. Units are based on the utility network units, which are located on the Source tab of the utility network layer properties pane. This property does not apply to junction and edge objects.	Double
split_content (Optional)	Specifies whether the associated content of a container will be split if the container feature is split. This parameter is only available if the association role is container and is only applicable for line features. SPLIT —The container's content will be split if the container feature is split. If a parallel content line feature is found, the content is also split and each section will be contained by the closest container feature. If the content line is not parallel, the content will be contained by the container feature that is closest to it. DO_NOT_SPLIT —The container's content will not be split if the container feature is split. If a parallel content line feature is found, the content will be contained by both sections of the container feature. If the content line is not parallel, the content will be contained by the container feature that is closest to it. This is the default.	Boolean

Code sample

SetAssociationRole example (Python window)

Set the container association role for the asset type transformer. The view scale has been set to 10, and the deletion semantics are restricted.
