A network attribute in a utility network.
A network attribute is an attribute that is copied and stored in the topological index. The utility network tracing task can read and make decisions using network attributes that are stored directly in the topological index. Without needing to fetch the individual features to get their attributes, the topological index provides performance that is orders of magnitude faster.
The network attributes in a topological index are limited to specific data types and aggregate size.

Whether the network attribute should be apportioned across the length of linear features. For example, if a point is chosen, 25% of the distance along an edge, 25% of the attribute's value is assigned to the 25% (shorter) part of the edge, and 75% of the attribute's value is assigned to the 75% (longer) part of the edge.

The AGSUtilityNetworkAttributeDataType
object for the AGSUtilityNetworkAttribute
object. The network attributes in a topological index are limited to specific data types.
|
readnonatomicstrong |
The AGSDomain
object associated with this network attribute. If no domain is assigned, nil
is returned.
|
readnonatomiccopy |
The name of the AGSUtilityNetworkAttribute
object.
|
readnonatomicstrong |
The AGSUtilityNetworkAttribute
object that is substituted for this AGSUtilityNetworkAttribute
object at tap features. This property is only set if AGSUtilityNetworkAttribute::substitution
property is set to YES
. Taps are special features, identified with the "Subnetwork Tap" category, that work with attribute substitution. See the online help for more information.

Whether the AGSUtilityNetworkAttribute
object is used as a substitution for another network attribute at tap features. If this value is YES
, this network attribute is the network attribute to substitute for the AGSUtilityNetworkAttribute::networkAttributeToSubstitute
property at tap features. Taps are special features, identified with the "Subnetwork Tap" category, that work with attribute substitution. See the online help for more information.

Indicates that the network attribute has been added by the system.
