Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

CoClasses that implement INetworkEvaluator

CoClasses and Classes Description
NetworkConstantEvaluator A container for describing a network attribute evaluator whose values are derived from a constant value.
NetworkEdgeTrafficEvaluator A container for members in time dependent travel time evaluator.
NetworkFieldEvaluator A container for describing a network attribute evaluator whose values are derived from object field attributes.
NetworkFunctionEvaluator A container for describing a network evaluator function.
NetworkGlobalTurnDelayEvaluator A container for describing a network attribute evaluator for global turn delay whose values are specified by global turn delay settings.
NetworkScriptEvaluator A container for describing a network attribute evaluator whose values are derived from VBScript expressions.
