FunctionBarrier Constructor

In This Topic

Initializes a new instance of the FunctionBarrier class.

Syntax

Visual Basic (Declaration)
C#

Public Function New( _
   ByVal function As Function, _
   ByVal comparisonOperator As Operator, _
   ByVal value As Double _
)

public FunctionBarrier( 
   Function function,
   Operator comparisonOperator,
   double value
)

Parameters

function: The Function that is used to calculate a value.
comparisonOperator: The Operator that is used to perform the comparison (equals, less than etc.).
value: The value that the functional expression is compared against.

Example

Create a FunctionBarrier

{
  // This routine creates a FunctionBarrier that stops traversal when the total shape length exceeds 1000 feet
  static void CreateFunctionBarrier(UtilityNetworkDefinition utilityNetworkDefinition, TraceConfiguration traceConfiguration)
  {
    // Create a NetworkAttribute object for the Shape length network attribute from the UtilityNetworkDefinition
    using NetworkAttribute shapeLengthNetworkAttribute = utilityNetworkDefinition.GetNetworkAttribute("Shape length");
    // Create a function that adds up shape length
    Add lengthFunction = new Add(shapeLengthNetworkAttribute);

    // Create a function barrier that stops traversal after 1000 feet
    FunctionBarrier distanceBarrier = new FunctionBarrier(lengthFunction, Operator.GreaterThan, 1000.0);

    // Set this function barrier
    traceConfiguration.Traversability.FunctionBarriers = new List<FunctionBarrier>() { distanceBarrier };
  }
}
