Constructor & Destructor Documentation

virtual isc::dhcp::HostReservationParser::~HostReservationParser ( )

inlinevirtual

Destructor.

Definition at line 22 of file host_reservation_parser.h.

Member Function Documentation

virtual const std::set<std::string>& isc::dhcp::HostReservationParser::getSupportedParameters ( const bool identifiers_only ) const

protectedpure virtual

Returns set of the supported parameters.

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.

Implemented in isc::dhcp::HostReservationParser6, and isc::dhcp::HostReservationParser4.

bool isc::dhcp::HostReservationParser::isIdentifierParameter ( const std::string & param_name ) const

protectedvirtual

Checks if the specified parameter is a host identifier.

Parameters

param_name Parameter name.

Returns: true if the parameter specifies host identifier, false otherwise.

Definition at line 178 of file host_reservation_parser.cc.

bool isc::dhcp::HostReservationParser::isSupportedParameter ( const std::string & param_name ) const

protectedvirtual

Checks if the specified parameter is supported by the parser.

Parameters

param_name Parameter name.

Returns: true if the parameter is supported, false otherwise.

Definition at line 183 of file host_reservation_parser.cc.

HostPtr isc::dhcp::HostReservationParser::parse	(	const SubnetID &	subnet_id,
		isc::data::ConstElementPtr	reservation_data
	)

finalvirtual

Parses a single entry for host reservation.

Parameters

subnet_id	Identifier of the subnet that the host is connected to.
reservation_data	Data element holding map with a host reservation configuration.

Returns: Pointer to the object representing parsed host.

Exceptions

DhcpConfigError If the configuration is invalid.

Definition at line 102 of file host_reservation_parser.cc.

HostPtr isc::dhcp::HostReservationParser::parseInternal	(	const SubnetID &	subnet_id,
		isc::data::ConstElementPtr	reservation_data
	)

protectedvirtual

Parses a single entry for host reservation.

This method is called by parse and it can be overridden in the derived classes to provide class specific parsing logic.

Parameters

subnet_id	Identifier of the subnet that the host is connected to.
reservation_data	Data element holding map with a host reservation configuration.

Returns: Pointer to the object representing parsed host.

Exceptions

DhcpConfigError If the configuration is invalid.

Reimplemented in isc::dhcp::HostReservationParser6, and isc::dhcp::HostReservationParser4.
