Member Function Documentation

parse()

OptionDefinitionPtr isc::cb::CBOptionDefParser::parse

(

data::ConstElementPtr

option_def

Sets the defaults and calls dhcp::OptionDefParser.

Parameters

option_def

a configuration entry to be parsed.

Returns

option definition of the parsed structure.

Exceptions

DhcpConfigError

if parsing was unsuccessful.
