Member Function Documentation

◆ parse()

CBOptionDefDelete isc::cb::CBOptionDefDeleteParser::parse ( data::ConstElementPtr option )

Parses an option into code + space pair.

The option specification is reduced to the code, space, and (optional) client-classes list. The code is mandatory, the space defaults to the address family standard space, and client-classes to an empty pointer. The parser takes, checks and returns them.

Parameters

option pointer to the content of option.

Returns: the code, space and client classes tuple.

Exceptions

DhcpConfigError	if the code does not exist, is not an integer
BadValue	if the space exists but is not a valid space name.
OutOfRange	if the code is out of range ([0..255] for DHCPv4, [0..65535] for DHCPv6).
