Detailed Description

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

Implements Transport for stream-based protocols.

Template Parameters

Protocol a stream-based protocol in Boost.Asio

Definition at line 43 of file stream-transport.hpp.

Member Typedef Documentation

◆ protocol

template<class Protocol>

using nfd::face::StreamTransport< Protocol >::protocol = Protocol

Definition at line 46 of file stream-transport.hpp.

Constructor & Destructor Documentation

◆ StreamTransport()

template<class Protocol>

nfd::face::StreamTransport< T >::StreamTransport ( typename protocol::socket && socket )

explicit

Construct stream transport.

Parameters

socket Protocol-specific socket for the created transport

Definition at line 111 of file stream-transport.hpp.

Member Function Documentation

◆ getSendQueueLength()

template<class T >

ssize_t nfd::face::StreamTransport< T >::getSendQueueLength ( )

overridevirtual

Returns: current send queue length of the transport (in octets)

Return values

QUEUE_UNSUPPORTED	transport does not support queue length retrieval
QUEUE_ERROR	transport was unable to retrieve the queue length

Reimplemented from nfd::face::Transport.

Definition at line 125 of file stream-transport.hpp.

◆ doClose()

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.

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

◆ deferredClose()

template<class T >

void nfd::face::StreamTransport< T >::deferredClose ( )

protected

Definition at line 168 of file stream-transport.hpp.

◆ doSend()

template<class T >

void nfd::face::StreamTransport< T >::doSend ( const Block & packet )

overrideprotectedvirtual

performs Transport specific operations to send a packet

Parameters

packet the packet to be sent, can be assumed to be valid and well-formed

Precondition: transport state is either UP or DOWN

Implements nfd::face::Transport.

Definition at line 183 of file stream-transport.hpp.
