      Fields 
      Modifier and Type Field Description
      private java.lang.String _externalName  
      private int _index  
      static int CLASS_MASK
      Multicast DNS uses the bottom 15 bits to identify the record class...
      Except for pseudo records like OPT.
      static int CLASS_UNIQUE
      For answers the top bit indicates that all other cached records are now invalid.
      For questions it indicates that we should send a unicast response.

        public static DNSRecordClass[] 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:

        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
