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 43 of file stream-transport.hpp.

Member Typedef Documentation

◆ protocol

template<class Protocol >
typedef Protocol nfd::face::StreamTransport< 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
socketProtocol-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_UNSUPPORTEDtransport does not support queue length retrieval
QUEUE_ERRORtransport was unable to retrieve the queue length

Reimplemented from nfd::face::Transport.

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

References nfd::face::getTxQueueLength(), NFD_LOG_FACE_WARN, and nfd::face::QUEUE_ERROR.

◆ 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.

◆ doSend()

template<class T >
void nfd::face::StreamTransport< T >::doSend ( const Block packet,
const EndpointId endpoint

overrideprotectedvirtual

performs Transport specific operations to send a packet

Parameters
packetthe packet to be sent, can be assumed to be valid and well-formed
endpointthe destination endpoint
Precondition
transport state is either UP or DOWN
