INetworkScriptEvaluator Interface

Provides access to members that specify the properties of a network attribute evaluator whose values are derived from VBScript expressions.

Members

	Name	Description
	GetExpression	Gets the VBScript calculator expression and pre-logic used to derive the values for this network evaluator.
	GetLanguage	Gets the script language
	SetExpression	Sets the VBScript calculator expression and pre-logic used to derive the values for this network evaluator.
	SetLanguage	Sets the script language

INetworkScriptEvaluator.GetExpression Method

Gets the VBScript calculator expression and pre-logic used to derive the values for this network evaluator.

Public Sub GetExpression ( _
    ByRef Expression As String, _
    ByRef preLogic As String _
)

public void GetExpression (
    ref string Expression,
    ref string preLogic
);

Remarks

When examining the preLogic parameter for code with multiple lines, the CarriageReturn-LineFeed character is at the line breaks.

INetworkScriptEvaluator.GetLanguage Method

Gets the script language

Public Sub GetLanguage ( _
    ByRef Language As String _
)

public void GetLanguage (
    ref string Language
);

INetworkScriptEvaluator.SetExpression Method

Sets the VBScript calculator expression and pre-logic used to derive the values for this network evaluator.

Public Sub SetExpression ( _
    ByVal Expression As String, _
    ByVal preLogic As String _
)

public void SetExpression (
    string Expression,
    string preLogic
);

Remarks

When specifying the preLogic parameter for code with multiple lines, use the CarriageReturn-LineFeed character at the line breaks.

INetworkScriptEvaluator.SetLanguage Method

Sets the script language

Public Sub SetLanguage ( _
    ByVal Language As String _
)

public void SetLanguage (
    string Language
);

Classes that implement INetworkScriptEvaluator

Classes	Description
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:

     addedTime
