inlineoverridevirtual

Reimplemented from nfd::face::Transport.

Definition at line 109 of file websocket-transport.hpp.

◆ receiveMessage()

void nfd::face::WebSocketTransport::receiveMessage ( const std::string & msg )

Translates a message into a Block and delivers it to the link service.

◆ beforeChangePersistency()

void nfd::face::WebSocketTransport::beforeChangePersistency ( ndn::nfd::FacePersistency newPersistency )

finalprotectedvirtual

invoked before persistency is changed

Exceptions

std::invalid_argument	new persistency is not supported
std::runtime_error	transition is disallowed

Implements nfd::face::Transport.

References ndn::nfd::FACE_PERSISTENCY_ON_DEMAND, and NFD_LOG_FACE_TRACE.

◆ doClose()

void nfd::face::WebSocketTransport::doClose ( )

finalprotectedvirtual

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.
