Update Is Connected (Utility Network)


Updates the IsConnected attribute on all the network features for the specified utility network based on connectivity.

Every feature in the line, device, and junction feature classes as well as every object in the domain network's junction object and edge object tables contains an Is connected attribute. This attribute helps identify isolated network features and objects by maintaining information about their connectivity to subnetwork controllers. When a feature is created, regardless of its connectivity, the Is connected attribute is set to unknown. This attribute is modified for network features depending on the operation being performed.

To learn more about this field, see Is connected attribute.
