Interface IEvaluatedNetworkAttribute

All Superinterfaces:

INetworkAttribute, Serializable

All Known Subinterfaces:

IEvaluatedNetworkAttribute2

All Known Implementing Classes:

EvaluatedNetworkAttribute

public interface IEvaluatedNetworkAttribute
extends INetworkAttribute, Serializable

Provides access to members that specify the properties of an evaluated attribute in a network dataset.

Superseded By

IEvaluatedNetworkAttribute2

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.

Method Summary

INetworkEvaluator	getDefaultEvaluator(int elementType) Evaluator used to derive attribute values for the given element type when an evaluator is not specified for a network element's source.
INetworkEvaluator	getEvaluator(INetworkSource networkSource, int direction) Evaluator used to derive values from the given network source for this network attribute.
void	setDefaultEvaluatorByRef(int elementType, INetworkEvaluator evaluator) Evaluator used to derive attribute values for the given element type when an evaluator is not specified for a network element's source.
void	setEvaluatorByRef(INetworkSource networkSource, int direction, INetworkEvaluator evaluator) Evaluator used to derive values from the given network source for this network attribute.
