Member Function Documentation

void ndn::UdpTransport::connect ( const Transport::ConnectionInfo &  connectionInfo, ElementListener &  elementListener  )

virtual

Connect according to the info in ConnectionInfo, and processEvents() will use elementListener.

Parameters

connectionInfo	A reference to a TcpTransport::ConnectionInfo.
elementListener	Not a shared_ptr because we assume that it will remain valid during the life of this object.

Reimplemented from ndn::Transport.

bool ndn::UdpTransport::isLocal ( const Transport::ConnectionInfo &  connectionInfo )

virtual

Determine whether this transport connecting according to connectionInfo is to a node on the current machine.

UDP transports are always non-local.

Parameters

connectionInfo

This is ignored.

Returns

False because UDP transports are always non-local.

Reimplemented from ndn::Transport.

void ndn::UdpTransport::processEvents ( )

virtual

Process any data to receive.

For each element received, call elementListener.onReceivedElement. This is non-blocking and will return immediately if there is no data to receive. You should normally not call this directly since it is called by Face.processEvents.

Exceptions

This	may throw an exception for reading data or in the callback for processing the data. If you call this from an main event loop, you may want to catch and log/disregard all exceptions.

Implements ndn::Transport.

void ndn::UdpTransport::send ( const uint8_t *  data, size_t  dataLength  )

virtual

Set data to the host.

Parameters

data	A pointer to the buffer of data to send.
dataLength	The number of bytes in data.

Reimplemented from ndn::Transport.
