Detailed Description

Provides support for an underlying protocol.

FaceSystem

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

create()

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

static

Return values

nullptr

if a factory with the given id is not registered

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

Referenced by nfd::face::FaceSystem::FaceSystem().

listRegistered()

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

static

Get all registered protocol factory ids.

Definition at line 54 of file protocol-factory.cpp.

Referenced by nfd::face::FaceSystem::FaceSystem().

getId()

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

staticnoexcept

Get id for this protocol factory.

face_system.factory-id config section is processed by the protocol factory.

getProvidedSchemes()

const std::set<std::string>& nfd::face::ProtocolFactory::getProvidedSchemes ( ) const

inline

Get FaceUri schemes accepted by this protocol factory.

Definition at line 115 of file protocol-factory.hpp.

References providedSchemes.

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 73 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 86 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.
