Detailed Description

a transport using TCP socket

Definition at line 40 of file tcp-transport.hpp.

Constructor & Destructor Documentation

◆ TcpTransport()

ndn::TcpTransport::TcpTransport ( const std::string &  host,
const std::string &  port = "6363" 
)
explicit

Definition at line 32 of file tcp-transport.cpp.

◆ ~TcpTransport()

ndn::TcpTransport::~TcpTransport ( )
overridedefault

Member Function Documentation

◆ connect()

void ndn::TcpTransport::connect ( boost::asio::io_service &  ioService,
const ReceiveCallback receiveCallback 
)
overridevirtual

asynchronously open the connection

Parameters
ioServiceio_service to create socket on
receiveCallbackcallback function when a TLV block is received; must not be empty
Exceptions
boost::system::system_errorconnection cannot be established

Reimplemented from ndn::Transport.

Definition at line 81 of file tcp-transport.cpp.

References ndn::Transport::connect(), and NDN_LOG_DEBUG.

◆ close()

void ndn::TcpTransport::close ( )
overridevirtual

Close the connection.

Implements ndn::Transport.

Definition at line 111 of file tcp-transport.cpp.

References NDN_LOG_DEBUG.

◆ pause()

void ndn::TcpTransport::pause ( )
overridevirtual

pause the transport

Postcondition
receiveCallback will not be invoked
Note
This operation has no effect if transport has been paused, or when connection is being established.

Implements ndn::Transport.

Definition at line 120 of file tcp-transport.cpp.

References NDN_LOG_DEBUG.

◆ resume()

void ndn::TcpTransport::resume ( )
overridevirtual

resume the transport

Postcondition
receiveCallback will be invoked
Note
This operation has no effect if transport is not paused, or when connection is being established.

Implements ndn::Transport.

Definition at line 129 of file tcp-transport.cpp.

References NDN_LOG_DEBUG.

◆ send() [1/2]

void ndn::TcpTransport::send ( const Block wire)
overridevirtual

send a TLV block through the transport

Implements ndn::Transport.

Definition at line 97 of file tcp-transport.cpp.

◆ send() [2/2]

void ndn::TcpTransport::send ( const Block header,
const Block payload 
)
overridevirtual

send two memory blocks through the transport

Scatter/gather API is utilized to send two non-consecutive memory blocks together (as part of the same message in datagram-oriented transports).

Implements ndn::Transport.

Definition at line 104 of file tcp-transport.cpp.

◆ create()

shared_ptr< TcpTransport > ndn::TcpTransport::create ( const std::string &  uri)
static

Create transport with parameters defined in URI.

Exceptions
Transport::Errorincorrect URI or unsupported protocol is specified

Definition at line 41 of file tcp-transport.cpp.

References getSocketHostAndPortFromUri().

◆ getSocketHostAndPortFromUri()

std::pair< std::string, std::string > ndn::TcpTransport::getSocketHostAndPortFromUri ( const std::string &  uri)

Definition at line 48 of file tcp-transport.cpp.

References ndn::FaceUri::getHost(), ndn::FaceUri::getPort(), and ndn::FaceUri::getScheme().
