Detailed Description

Class implementing a local channel to create faces.

Channel can create faces as a response to incoming IPC connections (UnixStreamChannel::listen needs to be called for that to work).

Definition at line 45 of file unix-stream-channel.hpp.

Constructor & Destructor Documentation

UnixStreamChannel()

nfd::face::UnixStreamChannel::UnixStreamChannel	(	const unix_stream::Endpoint &	endpoint,
		bool	wantCongestionMarking
	)

Create UnixStream channel for the specified endpoint.

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

Member Function Documentation

isListening()

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

inlineoverridevirtual

Returns whether the channel is listening.

Implements nfd::face::Channel.

Definition at line 72 of file unix-stream-channel.hpp.

Referenced by listen(), and ~UnixStreamChannel().

size()

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

inlineoverridevirtual

Returns the number of faces in the channel.

Implements nfd::face::Channel.

Definition at line 78 of file unix-stream-channel.hpp.

listen()

void nfd::face::UnixStreamChannel::listen	(	const FaceCreatedCallback &	onFaceCreated,
		const FaceCreationFailedCallback &	onAcceptFailed,
		int	backlog = boost::asio::local::stream_protocol::acceptor::max_connections
	)

Start listening.

Enable listening on the Unix socket, waiting for incoming connections, and creating a face when a connection is made.

Faces created in this way will have on-demand persistency.

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

Exceptions

Error
