Detailed Description

template<class Protocol, class Addressing = Unicast>
class nfd::face::DatagramTransport< Protocol, Addressing >

Implements Transport for datagram-based protocols.

Template Parameters

Protocol a datagram-based protocol in Boost.Asio

Definition at line 45 of file datagram-transport.hpp.

Member Typedef Documentation

template<class Protocol, class Addressing = Unicast>

typedef Protocol nfd::face::DatagramTransport< Protocol, Addressing >::protocol

Definition at line 48 of file datagram-transport.hpp.

Constructor & Destructor Documentation

template<class Protocol, class Addressing = Unicast>

nfd::face::DatagramTransport< T, U >::DatagramTransport ( typename protocol::socket && socket )

explicit

Construct datagram transport.

Parameters

socket Protocol-specific socket for the created transport

Definition at line 103 of file datagram-transport.hpp.

Member Function Documentation

template<class T , class U >

void nfd::face::DatagramTransport< T, U >::receiveDatagram	(	const uint8_t *	buffer,
		size_t	nBytesReceived,
		const boost::system::error_code &	error
	)

Receive datagram, translate buffer into packet, deliver to parent class.

template<class T , class U >

void nfd::face::DatagramTransport< T, U >::doClose ( )

overrideprotectedvirtual

performs Transport specific operations to close the transport

This is invoked once by close() after changing state to CLOSING. It will not be invoked by Transport class if the transport is already CLOSING or CLOSED.

When the cleanup procedure is complete, this method should change state to CLOSED. This transition can happen synchronously or asynchronously.

Implements nfd::face::Transport.
