Member Function Documentation

◆ connectToForwarder()

void nfd::face::InternalClientTransport::connectToForwarder ( InternalForwarderTransport *  forwarderTransport)

connect to a forwarder-side transport

Parameters
forwarderTransportthe forwarder-side transport to connect to; may be nullptr

The connected forwarder-side transport will be disconnected automatically if this method is called again, or if that transport is closed. It's safe to use InternalClientTransport without a connected forwarder-side transport: all sent packets would be lost, and nothing would be received.

Definition at line 85 of file internal-transport.cpp.

References nfd::face::InternalTransportBase::afterSend, nfd::face::Transport::afterStateChange, nfd::face::asyncReceive(), nfd::face::CLOSED, ndn::util::signal::ScopedConnection::disconnect(), and NFD_LOG_DEBUG.

◆ receiveFromLink()

void nfd::face::InternalClientTransport::receiveFromLink ( const Block &  packet)
overridevirtual

causes the transport to receive a link-layer packet

Implements nfd::face::InternalTransportBase.

Definition at line 106 of file internal-transport.cpp.

References ndn::Transport::m_receiveCallback.

◆ close()

void nfd::face::InternalClientTransport::close ( )
inlineoverridevirtual

Close the connection.

Implements ndn::Transport.

Definition at line 99 of file internal-transport.hpp.

◆ pause()

void nfd::face::InternalClientTransport::pause ( )
inlineoverridevirtual

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 104 of file internal-transport.hpp.

◆ resume()

void nfd::face::InternalClientTransport::resume ( )
inlineoverridevirtual

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 109 of file internal-transport.hpp.

◆ send() [1/2]

void nfd::face::InternalClientTransport::send ( const Block &  wire)
overridevirtual

send a TLV block through the transport

Implements ndn::Transport.

Definition at line 114 of file internal-transport.cpp.

References nfd::face::InternalTransportBase::afterSend, and emitSignal.

Referenced by send().

◆ send() [2/2]

void nfd::face::InternalClientTransport::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 120 of file internal-transport.cpp.

References ndn::encoding::Encoder::appendByteArray(), send(), ndn::Block::size(), and ndn::Block::wire().
