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 a UnixStream channel for the specified endpoint.

To enable the creation of faces upon incoming connections, one needs to explicitly call listen().

◆ ~UnixStreamChannel()

nfd::face::UnixStreamChannel::~UnixStreamChannel ( )
final

Member Function Documentation

◆ getDefaultMtu()

size_t nfd::face::Channel::getDefaultMtu ( ) const
inlinenoexceptinherited

Returns the default MTU for all faces created by this channel.

Definition at line 58 of file channel.hpp.

◆ getUri()

const FaceUri& nfd::face::Channel::getUri ( ) const
inlinenoexceptinherited

Definition at line 49 of file channel.hpp.

◆ isListening()

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

Returns whether the channel is listening.

Implements nfd::face::Channel.

Definition at line 59 of file unix-stream-channel.hpp.

◆ listen()

void nfd::face::UnixStreamChannel::listen ( const FaceCreatedCallback onFaceCreated,
const FaceCreationFailedCallback onAcceptFailed,
int  backlog = boost::asio::socket_base::max_listen_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
onFaceCreatedCallback to notify successful creation of the face
onAcceptFailedCallback to notify when channel fails (accept call returns an error)
backlogThe maximum length of the queue of pending incoming connections
Exceptions
std::system_error

protectednoexceptinherited

Definition at line 40 of file channel.cpp.

◆ setUri()

void nfd::face::Channel::setUri ( const FaceUri &  uri)
protectednoexceptinherited

Definition at line 34 of file channel.cpp.

◆ size()

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

Returns the number of faces in the channel.

Implements nfd::face::Channel.
