A HeapClient class that adds slot/signal signalling, connection/response timeouts, and input line buffering.
The following pure virtual functions must be implemented by derived classes: onConnect(), onReceive(), onDelete(), and onSendComplete().
The intention is that derived classes use the virtual functions for event notification while the slot/signal event notifications are used by the containing object (in particular so that the container is informed when the client object deletes itself).
| G::Slot::Signal0 & GNet::Client::connectedSignal | ( | ) |
Returns a signal that indicates that the client has successfully connected to the server.
Definition at line 95 of file gclient.cpp.
| G::Slot::Signal1< std::string > & GNet::Client::doneSignal | ( | ) |
Returns a signal that indicates that client processing is complete.
The first signal parameter is a failure reason, or the empty string on success. The second parameter gives some idea of whether the connection can be retried later.
Definition at line 85 of file gclient.cpp.
| G::Slot::Signal2< std::string, std::string > & GNet::Client::eventSignal | ( | ) |
Returns a signal that indicates that something interesting has happened.
The first signal parameter is one of "connecting", "connected", "sending", "failed" (on error) or "done" (for normal termination). Derived clases may emit other events over this channel.
Definition at line 90 of file gclient.cpp.
|
protectedpure virtual |
Called when a complete line is received from the peer.
The implementation should return false if it needs to stop further onReceive() calls being generated from data already received and buffered, if for example the object has just deleted itself.
| G::Slot::Signal0 & GNet::Client::secureSignal | ( | ) |
Returns a signal that indicates that the security layer has been successfully established.
