RailwayCrossingWarningListener class abstract
This abstract class should be implemented in order to receive railway crossing warnings.
Note: The railway crossing warner can be either a zone warner or a point warner, depending
on whether the railroad crossing warning is given for a railroad crossing zone or just a point. This
means that for a railway crossing there will can be either 2 or 3 warnings emitted. In case the railroad
crossing is a zone warner then 3 warnings will be emitted with the RailwayCrossingWarning.distance_type set to DistanceType.AHEAD,
DistanceType.REACHED and lastly DistanceType.PASSED when the end of the railway crossing is passed. In
case the railroad crossing is a point warner then 2 warnings will be emitted with the RailwayCrossingWarning.distance_type
set to DistanceType.AHEAD and DistanceType.PASSED when the end of the railway crossing is passed.
