Protocol factory for UDP over IPv4 and IPv6.

Member Typedef Documentation

using nfd::face::ProtocolFactory::CtorParams = ProtocolFactoryCtorParams

Member Function Documentation

unique_ptr< ProtocolFactory > nfd::face::ProtocolFactory::create	(	const std::string &	id,
		const CtorParams &	params
	)

staticinherited

Create a protocol factory instance.

Return values

nullptr if a factory with the given id is not registered

Definition at line 42 of file protocol-factory.cpp.

shared_ptr< UdpChannel > nfd::face::UdpFactory::createChannel	(	const udp::Endpoint &	localEndpoint,
		time::nanoseconds	idleTimeout
	)

Create UDP-based channel using udp::Endpoint.

udp::Endpoint is really an alias for boost::asio::ip::udp::endpoint.

If this method is called twice with the same endpoint, only one channel will be created. The second call will just return the existing channel.

If a multicast face is already active on the same local endpoint, the creation fails and an exception is thrown.

Returns: always a valid pointer to a UdpChannel object, an exception is thrown if it cannot be created.

Exceptions

UdpFactory::Error

Definition at line 292 of file udp-factory.cpp.

void nfd::face::ProtocolFactory::createFace	(	const CreateFaceRequest &	req,
		const FaceCreatedCallback &	onCreated,
		const FaceCreationFailedCallback &	onFailure
	)

inherited

Create a unicast face.

Parameters

req	request object containing the face creation parameters
onCreated	callback if face creation succeeds or face already exists; the settings of an existing face are not updated if they differ from the request
onFailure	callback if face creation fails

Definition at line 86 of file protocol-factory.cpp.

shared_ptr< Face > nfd::face::UdpFactory::createMulticastFace	(	const shared_ptr< const ndn::net::NetworkInterface > &	netif,
		const boost::asio::ip::address &	localAddress,
		const udp::Endpoint &	multicastEndpoint
	)

Create a multicast UDP face.

udp::Endpoint is really an alias for boost::asio::ip::udp::endpoint.

The face will join the specified multicast group.

If this method is called twice with the same set of arguments, only one face will be created. The second call will just return the existing face.

If a UDP channel, unicast face, or multicast face already exists on the same combination of local address and multicast port, the creation fails and an exception is thrown.

Parameters

netif	the network interface to which the face will be bound
localAddress	the local IP address to which the face will be bound
multicastEndpoint	the multicast endpoint (multicast group and port number)

Returns: always a valid shared pointer to the created face; an exception is thrown if the face cannot be created.

Exceptions

UdpFactory::Error

Definition at line 317 of file udp-factory.cpp.

shared_ptr< Face > nfd::face::ProtocolFactory::createNetdevBoundFace	(	const FaceUri &	remote,
		const shared_ptr< const ndn::net::NetworkInterface > &	netdev
	)

inherited

Create a netdev-bound face.

Parameters

remote	remote FaceUri, must be canonical
netdev	local network interface

Returns: new face

Exceptions

Error cannot create a face using specified arguments

Note: The caller must ensure there is no existing netdev-bound face with same remote FaceUri on the same local network interface.

std::vector< shared_ptr< const Channel > > nfd::face::ProtocolFactory::getChannels ( ) const

void nfd::face::ProtocolFactory::processConfig	(	OptionalConfigSection	configSection,
		FaceSystem::ConfigContext &	context
	)

inherited

Process face_system subsection that corresponds to this protocol factory id.

Parameters

configSection	the configuration section or boost::none to indicate it is omitted
context	provides access to data structures and contextual information

Exceptions

ConfigFile::Error invalid configuration

Definition at line 73 of file protocol-factory.cpp.

template<typename PF >

static void nfd::face::ProtocolFactory::registerType ( const std::string & id = PF::getId() )

inlinestaticinherited

Template Parameters

PF	subclass of ProtocolFactory

Parameters

id	factory identifier
