Trace Function Barrier
An UtilityTraceFunctionBarrier stops continued traversal when a comparison expression evaluates as true. An UtilityTraceFunctionBarrier performs a comparison expression between the current results of an UtilityTraceFunction and a given value. Remember that an UtilityTraceFunction references an UtilityNetworkAttribute and a calculation that is applied to it (Min, Max, Count, etc.) Once the comparison evaluates as true, network traversal stops.
