A container for describing a network attribute evaluator whose values are derived from VBScript expressions.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Description
A NetworkScriptEvaluator is an evaluator that assigns network attribute values based on some VB Script code. It allows you to compose arbitrarily complex expressions that combine multiple network attribute values to calculate a new attribute.
The NetworkScriptEvaluator has its CacheAttribute property equal to False, unlike the NetworkConstantEvaluator and NetworkFieldEvaluator. This means that it does not evaluate its code when the network is built, but when a network solver requires the result of that calculation. It is designed for dynamic analysis of a network under changing conditions.
