    • fromVersion

      static <E extends Enum<E> & SessionVersion> E fromVersion(E[] values, int version, String label)
      Resolves the given numeric version to its corresponding enum constant.
      Type Parameters:
      E - the enum type, which must also implement SessionVersion
      Parameters:
      values - the enum constants to search (typically E.values())

      Throws:
      ConversionException - if no constant matches the given version
