      • values

        public static HAProxyProtocolVersion[] 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 (HAProxyProtocolVersion c : HAProxyProtocolVersion.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static HAProxyProtocolVersion 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
      • valueOf

        public static HAProxyProtocolVersion valueOf​(byte verCmdByte)
        Returns the HAProxyProtocolVersion represented by the highest 4 bits of the specified byte.
        Parameters:
        verCmdByte - protocol version and command byte
      • byteValue

        public byte byteValue()
        Returns the byte value of this version.
