Detailed Description

Implements the logic for the Option6ClientFqdn class.

The purpose of the class is to separate the implementation details of the Option6ClientFqdn class from the interface. This implementation uses kea-libdns classes to process FQDNs. At some point it may be desired to split kea-libdhcp++ from kea-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.

isc::dhcp::Option6ClientFqdnImpl::Option6ClientFqdnImpl	(	const uint8_t	flags,
		const std::string &	domain_name,
		const Option6ClientFqdn::DomainNameType	name_type
	)

Constructor, from domain name.

Parameters

flags	A value of the flags option field.
domain_name	A domain name carried by the option given in the textual format.
name_type	A value which indicates whether domain-name is partial or fully qualified.

Member Function Documentation

void isc::dhcp::Option6ClientFqdnImpl::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.

Option6ClientFqdnImpl & isc::dhcp::Option6ClientFqdnImpl::operator= ( const Option6ClientFqdnImpl & source )

Assignment operator.

Parameters

source An object which is being assigned.

void isc::dhcp::Option6ClientFqdnImpl::parseWireData	(	OptionBufferConstIter	first,

	)

Parse the Option provided in the wire format.

Parameters

first	An iterator pointing to the beginning of the option data in the wire format.
last	An iterator pointing to the end of the option data in the wire format.
