    Traversability Property
    In This Topic
    Defines the criteria for stopping further traversal during a trace.
    Syntax
    public Traversability Traversability {get;}
    Public ReadOnly Property Traversability As Traversability
    Example
    Create a Condition to compare a Network Attribute against a set of values
    // Create a NetworkAttribute object for the Lifecycle network attribute from the UtilityNetworkDefinition
    using (NetworkAttribute lifecycleNetworkAttribute = utilityNetworkDefinition.GetNetworkAttribute("Lifecycle"))
    {
      // Create a NetworkAttributeComparison that stops traversal if Lifecycle <> "In Design" (represented by the constant InDesign)
      NetworkAttributeComparison inDesignNetworkAttributeComparison = new NetworkAttributeComparison(lifecycleNetworkAttribute, Operator.NotEqual, InDesign);
    
      // Create a NetworkAttributeComparison to stop traversal if Lifecycle <> "In Service" (represented by the constant InService)
      NetworkAttributeComparison inServiceNetworkAttributeComparison = new NetworkAttributeComparison(lifecycleNetworkAttribute, Operator.NotEqual, InService);
    
      // Combine these two comparisons together with "And"
      And lifecycleFilter = new And(inDesignNetworkAttributeComparison, inServiceNetworkAttributeComparison);
      
      // Final condition stops traversal if Lifecycle <> "In Design" and Lifecycle <> "In Service"
      traceConfiguration.Traversability.Barriers = lifecycleFilter;
    }
    
    Create a FunctionBarrier
    // 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 };
    }
