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_only Indicates 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 301 of file host_reservation_parser.cc.

◆ parseInternal()

HostPtr isc::dhcp::HostReservationParser4::parseInternal	(	const SubnetID &	subnet_id,
		isc::data::ConstElementPtr	reservation_data,
		bool	encapsulate_options )

protectedvirtual

Parses a single host reservation for DHCPv4.

Parameters

subnet_id	Identifier of the subnet that the host is connected to.
reservation_data	Data element holding map with a host reservation configuration.
encapsulate_options	a boolean parameter indicating if the parsed options should be encapsulated with suboptions.

Returns: Pointer to the object representing parsed host.

Exceptions

DhcpConfigError If the configuration is invalid.

Reimplemented from isc::dhcp::HostReservationParser.
