NetworkScriptEvaluator | A container for describing a network attribute evaluator whose values are derived from VBScript expressions. |
Remarks
The INetworkScriptEvaluator interface accesses the code used by a NetworkScriptEvaluator object for calculating the attribute value for a network element. Any setup computations needed prior to calculate the attribute value are specified in the preLogic parameter. The value of the attribute is computed from the expression.
The example below shows the preLogic and expression for penalizing all left turns 20 seconds:
- PreLogic:
addedTime = 0
a = Turn.Angle
If a > 210 And a < 330 Then
addedTime = 20
End If
- Expression:
