Member Function Documentation

◆ client_connected()

void fawkes::FawkesNetworkHandler::client_connected ( unsigned int  clid)
pure virtual

Called when a new client connected.

If any actions need to be taken on your side this is the place to do it.

Parameters
clidclient ID of new client

Implemented in fawkes::NetworkLogger, fawkes::PluginNetworkHandler, fawkes::ConfigNetworkHandler, fawkes::BlackBoardNetworkHandler, and ExampleNetworkThread.

◆ client_disconnected()

void fawkes::FawkesNetworkHandler::client_disconnected ( unsigned int  clid)
pure virtual

Called when a client disconnected.

If any actions need to be taken on your side this is the place to do it. Note that you cannot send any further messages to this client!

Parameters
clidclient ID of disconnected client

Implemented in fawkes::NetworkLogger, fawkes::PluginNetworkHandler, fawkes::ConfigNetworkHandler, fawkes::BlackBoardNetworkHandler, and ExampleNetworkThread.

◆ handle_network_message()

void fawkes::FawkesNetworkHandler::handle_network_message ( FawkesNetworkMessage msg)
pure virtual

Called for incoming messages that are addressed to the correct component ID.

Note that this message should be processed really really fast! A good idea is to enqueue the message in an inbound queue (remember to ref() it!) and then process it in the next run of loop() or wakeup a processing thread.

Parameters
msgmessage to handle. If you want to keep this message you have to ref() it! It is guaranteed that the message will not be erased during the handleNetworkMessage() run, but afterwards no guarantee is made. So if you want to store the message internally for example for later processing you have to reference the message.

Implemented in fawkes::NetworkLogger, fawkes::PluginNetworkHandler, fawkes::ConfigNetworkHandler, fawkes::BlackBoardNetworkHandler, and ExampleNetworkThread.

◆ id()

unsigned short int fawkes::FawkesNetworkHandler::id ( ) const

Get the component ID for this handler.

Returns
component ID
