Detailed Description

Provides support for an underlying protocol.

A protocol factory provides support for an underlying protocol and owns Channel objects. It can process a subsection of the face_system configuration section and create channels and multicast faces accordingly.

Member Function Documentation

◆ create()

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

static

Create a protocol factory instance.

Return values

nullptr if a factory with the given id is not registered

Definition at line 41 of file protocol-factory.cpp.

◆ createFace()

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

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 85 of file protocol-factory.cpp.

◆ createNetdevBoundFace()

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

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.

◆ getId()

static const std::string& nfd::face::ProtocolFactory::getId ( )

staticnoexcept

◆ listRegistered()

std::set< std::string > nfd::face::ProtocolFactory::listRegistered ( )

static

Get all registered protocol factory IDs.

Definition at line 53 of file protocol-factory.cpp.

◆ processConfig()

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

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 72 of file protocol-factory.cpp.

◆ registerType()

template<typename PF >

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

inlinestatic

Register a protocol factory type.

Template Parameters

PF	subclass of ProtocolFactory

Parameters

id	factory identifier
