    • Method Detail

      • values

        public static Group[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (Group c : Group.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static Group valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.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
