CoClasses that implement IEvaluatedNetworkAttribute

CoClasses and Classes Description
EvaluatedNetworkAttribute A container for describing a network dataset attribute and its evaluators.

Remarks

The IEvaluatedNetworkAttribute interface is used to access the default and source evaluators of the evaluated network attribute.

To access the EvaluatedNetworkAttribute object for an existing network dataset attribute, use the Attribute, AttributeByID, or AttributeByName methods on the INetworkDataset interface.

The IEvaluatedNetworkAttribute interface is also used to define a new network attribute.  To create a new network attribute, cocreate an EvaluatedNetworkAttribute object, specify its properties using the INetworkAttribute and INetworkAttribute2 interfaces, specify its evaluators using the IEvaluatedNetworkAttribute interface, and pass the object to the INetworkBuild::AddAttribute method on the network dataset.
