filterBarriers

The collection of filter barriers. A regular barrier, specified by UtilityTraceParameters.barriers, prevents traversal which, when used with subnetwork-based traces, can prevent traversal to the subnetwork controller. Like UtilityTraceConfiguration.filter, filter barriers are evaluated in the second pass of a trace. Therefore, it can restrict the result set without impacting the ability to find subnetwork controllers from starting points.

One example of where filter barriers can be used is in the gas distribution domain. Filter barriers can be used to simulate the location of a squeeze-off when executing a valve isolation trace. The user can place a filter barrier at the proposed location of the squeeze-off and then verify its impact using a trace.
