      test - value to test against
      Returns:
      an equality predicate

      Parameters:
      values - to test against
      Returns:
      a "contained in" predicate

    • in

      default BuildablePredicate<T> in(R... collection)

      Parameters:
      collection - to test against
      Returns:
      a "contained in" predicate

    • identity
