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

§ protocol

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

§ DatagramTransport()

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

§ receiveDatagram()

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.

Definition at line 149 of file datagram-transport.hpp.

§ doClose()

template<class T , class U >

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

protectedvirtual

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.

Reimplemented in nfd::face::DECL_CLASS_FINAL, and nfd::face::DECL_CLASS_FINAL.

Definition at line 115 of file datagram-transport.hpp.

§ doSend()

template<class T , class U >

void nfd::face::DatagramTransport< T, U >::doSend ( Transport::Packet && packet )

protectedvirtual

performs Transport specific operations to send a packet

Parameters

packet the packet, which must be a well-formed TLV block

Precondition: state is either UP or DOWN

Implements nfd::face::Transport.

Definition at line 136 of file datagram-transport.hpp.
