Detailed Description

Class implementing UDP-based channel to create faces.

Definition at line 42 of file udp-channel.hpp.

Constructor & Destructor Documentation

nfd::UdpChannel::UdpChannel	(	const udp::Endpoint &	localEndpoint,
		const time::seconds &	timeout
	)

Create UDP channel for the local endpoint.

To enable creation of faces upon incoming connections, one needs to explicitly call UdpChannel::listen method. The created socket is bound to the localEndpoint. reuse_address option is set

Exceptions

UdpChannel::Error

if bind on the socket fails

Definition at line 36 of file udp-channel.cpp.

References nfd::Channel::setUri().

Member Function Documentation

void nfd::UdpChannel::listen	(	const FaceCreatedCallback &	onFaceCreated,
		const ConnectFailedCallback &	onReceiveFailed
	)

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

Once a face is created, if it doesn't send/receive anything for a period of time equal to timeout, it will be destroyed

Todo:

this functionality has to be implemented

Exceptions

UdpChannel::Error

if called multiple times

Definition at line 46 of file udp-channel.cpp.

void nfd::UdpChannel::connect	(	const udp::Endpoint &	remoteEndpoint,
		ndn::nfd::FacePersistency	persistency,
		const FaceCreatedCallback &	onFaceCreated,
		const ConnectFailedCallback &	onConnectFailed
	)

Create a face by establishing connection to remote endpoint.

Exceptions

UdpChannel::Error

if bind or connect on the socket fail

Definition at line 69 of file udp-channel.cpp.

size_t nfd::UdpChannel::size

(

)

const

Get number of faces in the channel.
