All Implemented Interfaces:

An empty marker that does nothing itself, but can be used as a base marker when you want to conditionally chain other markers with LogstashMarker.and(Marker). For example: 
     LogstashMarker marker = Markers.empty();
     if (condition1) {
         marker = marker.and(Markers.append("fieldName1", value1);
     }
     if (condition2) {
         marker = marker.and(Markers.append("fieldName2", value2);
     }
