Detailed Description

Implements the logic for the Option6ClientFqdn class.

The purpose of the class is to separate the implementation details of the Option4ClientFqdn class from the interface. This implementation uses libdns classes to process FQDNs. At some point it may be desired to split libdhcp++ from libdns. In such case the implementation of this class may be changed. The declaration of the Option6ClientFqdn class holds the pointer to implementation, so the transition to a different implementation would not affect the header file.

Member Function Documentation

◆ checkFlags()

void isc::dhcp::Option4ClientFqdnImpl::checkFlags	(	const uint8_t	flags,
		const bool	check_mbz )

static

Check if flags are valid.

In particular, this function checks if the N and S bits are not set to 1 in the same time.

Parameters

flags	A value carried by the flags field of the option.
check_mbz	A boolean value which indicates if this function should check if the MBZ bits are set (if true). This parameter should be set to false when validating flags in the received message. This is because server should ignore MBZ bits in received messages.

Exceptions

InvalidOption6FqdnFlags if flags are invalid.
