Update Subnetwork (Utility Network)

Summary

Updates subnetwork information in the Subnetworks table, the SubnetLine feature class, and subnetwork system diagrams for the specified subnetworks. Also certain attributes are created or updated for subnetwork features. A record for any new subnetworks will be generated, the records for any deleted subnetworks will be removed, and the shape and information for any modified subnetworks will be updated.

Usage

• The following requirements must be met when working with an enterprise geodatabase:

  • The utility network must be registered as branch versioned.
  • The input utility network must be from a utility network service.
  • If this tool is executed on the default version, the geometry, subnetwork name attribute, and propagated fields of the SubnetLine feature class are updated in place. If executed against a named version, the default behavior (without events) limits updates to features and objects edited in the version. The edit mode can be changed to use events (with events). This option executes geodatabase behavior and can be set in the subnetwork definition for both the default version and named versions.

• This tool creates or updates network diagrams for the updated subnetworks if a diagram template was specified when setting the subnetwork definition.

• Any edits must be saved prior to running this tool.

• The network topology must be enabled.

• No dirty areas exist that intersect with subnetwork features.

Syntax

arcpy.un.UpdateSubnetwork(in_utility_network, domain_network, tier, {all_subnetworks_in_tier}, {subnetwork_name}, {continue_on_failure}, {condition_barriers}, {function_barriers}, {include_barriers}, {traversability_scope}, {propagators})

Parameter	Explanation	Data Type
in_utility_network	The utility network that contains the subnetwork.	Utility Network; Utility Network Layer
domain_network	The domain network that contains the subnetwork.	String
tier	The tier that contains the subnetwork.	String
all_subnetworks_in_tier (Optional)	Specifies whether all subnetworks in the tier are updated. To update a subset of subnetworks in the tier, use the subnetwork_name parameter. ALL_SUBNETWORKS_IN_TIER —Updates all subnetworks in the tier. This option uses asynchronous processing to update the subnetworks using the system UtilityNetworkTools geoprocessing service. The service is reserved for utility network geoprocessing tasks and has a longer default timeout setting. This is the default. SPECIFIC_SUBNETWORK —Updates only the subnetworks specified in the subnetwork_name parameter.	Boolean
subnetwork_name (Optional)	The name of the subnetworks to update. If all subnetworks will be updated using the all_subnetworks_in_tier parameter, this parameter is ignored.	String
continue_on_failure (Optional)	Specifies whether to stop the update process if a subnetwork fails to update when updating multiple subnetworks. CONTINUE_ON_FAILURE —Continues to update subnetworks upon failure. STOP_ON_FAILURE —Stops updating subnetworks if a failure occurs. This is the default.	Boolean
condition_barriers [[Name, Operator, Type, Value, Combine Using],...] (Optional)	Sets a traversability barrier condition on features based on a comparison to a network attribute or check for a category string. A condition barrier uses a network attribute, an operator and a type, and an attribute value. For example, stop a trace when a feature has the Device Status attribute equal to the specific value of Open. When a feature meets this condition, the trace stops. If you're using more than one attribute, you can use the Combine using parameter to define an And or an Or condition. Condition barrier components are as follows: Name—Choose to filter by any network attribute defined in the system. Operator—Choose from a number of different operators. Type—Choose a specific value or network attribute from the value that is specified in the name parameter. Value—Set a specific value of the input attribute type that would cause termination based on the operator value. Combine Using—Set this value if you have multiple attributes to add. You can combine them using an And or an Or condition. The condition barrier Operator values are as follows: IS_EQUAL_TO —The attribute is equal to the value. DOES_NOT_EQUAL —The attribute is not equal to the value. IS_GREATER_THAN —The attribute is greater than the value. IS_GREATER_THAN_OR_EQUAL_TO —The attribute is greater than or equal to the value. IS_LESS_THAN —The attribute is less than the value. IS_LESS_THAN_OR_EQUAL_TO —The attribute is less than or equal to the value. INCLUDES_THE_VALUES —A bitwise AND operation where all bits in the value are present in the attribute (bitwise AND == value). DOES_NOT_INCLUDE_THE_VALUES —A bitwise AND operation where not all of the bits in the value are present in the attribute (bitwise AND != value). INCLUDES_ANY —A bitwise AND operation where at least one bit in the value is present in the attribute (bitwise AND == True). DOES_NOT_INCLUDE_ANY —A bitwise AND operation where none of the bits in the value are present in the attribute (bitwise AND == False). The condition barrier type options are as follows: SPECIFIC_VALUE —Filter by a specific value. NETWORK_ATTRIBUTE —Filter by a network attribute. The Combine Using values are as follows: AND —Combine the condition barriers. OR —Use if either condition barrier is met. Note: This parameter is only available via Python.

function_barriers [[Function, Attribute, Operator, Value, Use Local Values],...] (Optional)	Sets a traversability barrier on features based on a function. Function barriers can be used to do such things as restrict how far the trace travels from the starting point, or set a maximum value to stop a trace. For example, the length of each line traveled is added to the total distance traveled so far. When the total length traveled reaches the value specified, the trace stops. Function barrier components are as follows: Function—Choose from a number of different calculation functions. Attribute—Choose to filter by any network attribute defined in the system. Operator—Choose from a number of different operators. Value—Set a specific value of the input attribute type that, if discovered, will cause the termination. Use Local Values—Calculate values in each direction as opposed to an overall global value, for example, for a function barrier that is calculating the sum of Shape length where the trace terminates if the value is greater than or equal to 4. In the global case, after you have traversed two edges with a value of 2, you have already reached a shape length sum of 4, so the trace stops. If local values are used, the local values along each path change, so the trace goes farther. TRUE —Use local values. FALSE —Use global values. This is the default. Possible values for the function barrier function options are as follows: AVERAGE —The average of the input values. COUNT —The number of features. MAX —The maximum of the input values. MIN —The minimum of the input values. ADD —Add the values. SUBTRACT —Subtract the values. Subnetwork controllers and loops trace types do not support the subtract function. For example, the starting point feature has a value of 20. The next feature has a value of 30. If you use the minimum function, the result is 20, maximum is 30, add is 50, average is 25, count is 2, and subtract is -10. The function barrier operator value options are as follows: IS_EQUAL_TO —The attribute is equal to the value. DOES_NOT_EQUAL —The attribute is not equal to the value. IS_GREATER_THAN —The attribute is greater than the value. IS_GREATER_THAN_OR_EQUAL_TO —The attribute is greater than or equal to the value. IS_LESS_THAN —The attribute is less than the value. IS_LESS_THAN_OR_EQUAL_TO —The attribute is less than or equal to the value. INCLUDES_THE_VALUES —A bitwise AND operation where all bits in the value are present in the attribute (bitwise AND == value). DOES_NOT_INCLUDE_THE_VALUES —A bitwise AND operation where not all of the bits in the value are present in the attribute (bitwise AND != value). INCLUDES_ANY —A bitwise AND operation where at least one bit in the value is present in the attribute (bitwise AND == True). DOES_NOT_INCLUDE_ANY —A bitwise AND operation where none of the bits in the value are present in the attribute (bitwise AND == False). Note: This parameter is only available via Python.	Value Table
include_barriers (Optional)	Specifies whether the traversability barrier features are included in the trace results. Traversability barriers are optional even if they have been preset in the subnetwork definition. INCLUDE_BARRIERS —Traversability barriers are included in the trace results. This is the default. EXCLUDE_BARRIERS —Traversability barriers are not included in the trace results. Note: This parameter is only available via Python and ModelBuilder.	Boolean
traversability_scope (Optional)	Specifies the type of traversability to enforce. Traversability scope dictates whether traversability is enforced at junctions, edges, or both. For example, if a condition barrier is defined to stop the trace if DEVICESTATUS is equal to Open and traversability scope is set to edges only, the trace would not stop even if the trace encounters an open device, because the DEVICESTATUS is only applicable for junctions. In other words, this parameter indicates to the trace whether to ignore junctions, edges, or both. BOTH_JUNCTIONS_AND_EDGES —Apply traversability to both junctions and edges. This is the default. JUNCTIONS_ONLY —Apply traversability to only junctions. EDGES_ONLY —Apply traversability to only edges. Note: This parameter is only available via Python and ModelBuilder.	String
propagators [[Attribute, Substitution Attribute, Function, Operator, Value],...] (Optional)	Specifies the network attributes to propagate as well as how that propagation will occur during a trace. Propagated class attributes denote the key values on subnetwork controllers that are disseminated to the rest of the features in the subnetwork. For example, in an electric distribution model, you can propagate the phase value. Propagators components are as follows: Attribute—Filter by any network attribute defined in the system. Substitution Attribute—Use a substituted value instead of bitset network attribute values. Substitutions are encoded based on the number of bits in the network attribute being propagated. A substitution is a mapping of each bit in phase to another bit. For example, for Phase AC, one substitution could map bit A to B, and bit C to null. In this example, the substitution for 1010 (Phase AC) is 0000-0010-0000-0000 (512). The substitution captures the mapping so you know that Phase A was mapped to B and Phase C was mapped to null, and not the other way around (that is, Phase A was not mapped to null and Phase C was not mapped to B). Function—Choose from a number of calculation functions. Operator—Choose from a number of operators. Value—Provide a specific value for the input attribute type that would cause termination based on the operator value. Possible values for the propagators function are as follows: PROPAGATED_BITWISE_AND —Compare the values from one feature to the next. PROPAGATED_MIN —Get the minimum value. PROPAGATED_MAX —Get the maximum value. The propagator operator values are as follows: IS_EQUAL_TO —The attribute is equal to the value. DOES_NOT_EQUAL —The attribute is not equal to the value. IS_GREATER_THAN —The attribute is greater than the value. IS_GREATER_THAN_OR_EQUAL_TO —The attribute is greater than or equal to the value. IS_LESS_THAN —The attribute is less than the value. IS_LESS_THAN_OR_EQUAL_TO —The attribute is less than or equal to the value. INCLUDES_THE_VALUES —A bitwise AND operation where all bits in the value are present in the attribute (bitwise AND == value). DOES_NOT_INCLUDE_THE_VALUES —A bitwise AND operation where not all of the bits in the value are present in the attribute (bitwise AND != value). INCLUDES_ANY —A bitwise AND operation where at least one bit in the value is present in the attribute (bitwise AND == True). DOES_NOT_INCLUDE_ANY —A bitwise AND operation where none of the bits in the value are present in the attribute (bitwise AND == False). Note: This parameter is only available via Python and ModelBuilder.	Value Table
