  • Method Details

    • values

      public static Group[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static Group valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null

    • getId

      public int getId()
      Returns the numeric identifier for this group as defined in the TLS supported groups registry.
      Returns:
      the numeric group identifier

    • valueOf

      public static Group valueOf(int groupId)
      Returns the Group enum constant for the given numeric group identifier.
      Parameters:
      groupId - The numeric group identifier
      Returns:
      The corresponding Group, or null if not found
