Member Function Documentation

◆ getSupportedParameters()

const std::set< std::string > & isc::dhcp::HostReservationParser4::getSupportedParameters ( const bool  identifiers_only) const
protectedvirtual

Returns set of the supported parameters for DHCPv4.

Parameters
identifiers_onlyIndicates if the function should only return supported host identifiers (if true) or all supported parameters (if false).
Returns
Set of supported parameter names.

Implements isc::dhcp::HostReservationParser.

Definition at line 242 of file host_reservation_parser.cc.

◆ parseInternal()

HostPtr isc::dhcp::HostReservationParser4::parseInternal ( const SubnetID subnet_id,
isc::data::ConstElementPtr  reservation_data 
)
protectedvirtual

Parses a single host reservation for DHCPv4.

Parameters
subnet_idIdentifier of the subnet that the host is connected to.
reservation_dataData element holding map with a host reservation configuration.
Returns
Pointer to the object representing parsed host.
Exceptions
DhcpConfigErrorIf the configuration is invalid.

Reimplemented from isc::dhcp::HostReservationParser.
