Defines the criteria for stopping further traversal during a trace.
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 };
