All Implemented Interfaces:

public class StateSet extends StatefulMetric<StateSetDataPoint,io.prometheus.metrics.core.metrics.StateSet.DataPoint> implements StateSetDataPoint
StateSet metric. Example: 

 public enum Feature {

     FEATURE_1("feature1"),
     FEATURE_2("feature2");

     private final String name;

     Feature(String name) {
         this.name = name;
     }

     // Override
     public String toString() {
         return name;
     }
 }

 public static void main(String[] args) {

     StateSet stateSet = StateSet.builder()
             .name("feature_flags")
             .help("Feature flags")
             .labelNames("env")
             .states(Feature.class)
             .register();

     stateSet.labelValues("dev").setFalse(FEATURE_1);
     stateSet.labelValues("dev").setTrue(FEATURE_2);
 }
The example above shows how to use a StateSet with an enum. You don't have to use enum, you can use regular strings as well.
