Network Attribute Parameter

Zusammenfassung

Provides information about attribute parameters associated with the network analysis layer.

Auswertung

The attributeName, parameterName, and parameterValue properties for the attribute parameter object are dynamic. This means that the total number of properties supported by a given attribute parameter object depends on the parameterCount property. For example, if the value of the parameterCount property is 2, then the attribute parameter object will support attributeName0, attributeName1, parameterName0, parameterName1, parameterValue0, and parameterValue1 properties.
