      int count​(E value)
      Count the number of times a specific value appears.
      int count​(E value, boolean negate)
      Generalised version of count(Enum) that allows to instead count the number of times something else is set.
      int[] extract​(E value)
      Get the indices where this value is set.
      int[] extract​(E value, boolean negate)

      void extract​(E value, boolean negate, int[] receiver)
      Generalised version of extract(Enum, boolean) that allows to supply the array the resulting indices should be written to.
