Detailed Description

Class implementing TCP-based channel to create faces.

Channel can create faces as a response to incoming TCP connections (TcpChannel::listen needs to be called for that to work) or explicitly after using TcpChannel::connect method.

Definition at line 49 of file tcp-channel.hpp.

Constructor & Destructor Documentation

TcpChannel()

nfd::face::TcpChannel::TcpChannel	(	const tcp::Endpoint &	localEndpoint,
		bool	wantCongestionMarking,
		DetermineFaceScopeFromAddress	determineFaceScope
	)

Create TCP channel for the local endpoint.

To enable creation faces upon incoming connections, one needs to explicitly call TcpChannel::listen method.

Member Function Documentation

isListening()

bool nfd::face::TcpChannel::isListening ( ) const

inlineoverridevirtual

Returns whether the channel is listening.

Implements nfd::face::Channel.

Definition at line 62 of file tcp-channel.hpp.

Referenced by listen().

size()

size_t nfd::face::TcpChannel::size ( ) const

inlineoverridevirtual

Returns the number of faces in the channel.

Implements nfd::face::Channel.

Definition at line 68 of file tcp-channel.hpp.

listen()

void nfd::face::TcpChannel::listen	(	const FaceCreatedCallback &	onFaceCreated,
		const FaceCreationFailedCallback &	onAcceptFailed,
		int	backlog = boost::asio::ip::tcp::acceptor::max_connections
	)

Enable listening on the local endpoint, accept connections, and create faces when remote host makes a connection.

Parameters

onFaceCreated	Callback to notify successful creation of the face
onAcceptFailed	Callback to notify when channel fails (accept call returns an error)
backlog	The maximum length of the queue of pending incoming connections

Definition at line 52 of file tcp-channel.cpp.

connect()

void nfd::face::TcpChannel::connect	(	const tcp::Endpoint &	remoteEndpoint,
		const FaceParams &	params,
		const FaceCreatedCallback &	onFaceCreated,
		const FaceCreationFailedCallback &	onConnectFailed,
		time::nanoseconds	timeout = 8_s
	)

Create a face by establishing a TCP connection to remoteEndpoint.
