Detailed Description

Parser for a list of option definitions.

This parser iterates over all configuration entries that define option definitions and creates instances of these definitions. If the parsing is successful, the collection of created definitions is put into the provided storage.

Constructor & Destructor Documentation

◆ OptionDefListParser()

isc::dhcp::OptionDefListParser::OptionDefListParser ( const uint16_t  address_family)

Constructor.

Parameters
address_familyAddress family: AF_INET or AF_INET6.

Definition at line 234 of file dhcp_parsers.cc.

Member Function Documentation

◆ parse()

void isc::dhcp::OptionDefListParser::parse ( CfgOptionDefPtr  cfg,
isc::data::ConstElementPtr  def_list 
)

Parses a list of option definitions, create them and store in cfg.

This method iterates over def_list, which is a JSON list of option definitions, then creates corresponding option definitions and store them in the configuration structure.

Parameters
def_listJSON list describing option definitions
cfgparsed option definitions will be stored here
