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 45 of file tcp-channel.hpp.

Constructor & Destructor Documentation

TcpChannel()

nfd::TcpChannel::TcpChannel ( const tcp::Endpoint &  localEndpoint )

explicit

Create TCP channel for the local endpoint.

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

Definition at line 37 of file tcp-channel.cpp.

References nfd::Channel::setUri().

Member Function Documentation

listen()

void nfd::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

connect()

void nfd::TcpChannel::connect	(	const tcp::Endpoint &	remoteEndpoint,
		bool	wantLocalFieldsEnabled,
		const FaceCreatedCallback &	onFaceCreated,
		const FaceCreationFailedCallback &	onConnectFailed,
		const time::seconds &	timeout = time::seconds(4)
	)

Create a face by establishing connection to remote endpoint.
