Detailed Description

template<class Protocol>
class nfd::face::StreamTransport< Protocol >

Implements Transport for stream-based protocols.

Template Parameters
Protocola stream-based protocol in Boost.Asio

Definition at line 42 of file stream-transport.hpp.

Member Typedef Documentation

template<class Protocol>
typedef Protocol nfd::face::StreamTransport< Protocol >::protocol

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

Constructor & Destructor Documentation

template<class Protocol>
nfd::face::StreamTransport< T >::StreamTransport ( typename protocol::socket &&  socket)
explicit

Construct stream transport.

Parameters
socketProtocol-specific socket for the created transport

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

References nfd::face::StreamTransport< Protocol >::startReceive().

Member Function Documentation

template<class T >
void nfd::face::StreamTransport< T >::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.

template<class T >
void nfd::face::StreamTransport< T >::doSend ( Transport::Packet &&  packet)
overrideprotectedvirtual

performs Transport specific operations to send a packet

Parameters
packetthe packet, which must be a well-formed TLV block
Precondition
state is either UP or DOWN
