Public Member Functions
template<int AZMQType>
void	initialize (const std::string &pubSocketAddress, const std::string &subSocketAddress, const std::string &socketAddress, bool bind)
	Initialize the multicast and a data socket of the given type.
void	initialize (const std::string &pubSocketAddress, const std::string &subSocketAddress)
	Initialize only the multicast.
void	terminate (bool sendGoodbye=true)
	Terminate the sockets properly.
void	reset ()
	Reset the sockets. ATTENTION: this does not close the sockets! Use only after forks to not clean up to times.
void	subscribe (EMessageTypes messageType)
	Subscribe to the given multicast message type.
template<class AZMQMessage >
void	send (AZMQMessage message) const
	Send a message over the data socket.
void	send (zmq::message_t &message) const
	Send a zmq message over the data socket. ATTENTION: we are taking ownership here!
template<class AZMQMessage >
void	publish (AZMQMessage message) const
	Publish the message to the multicast.
bool	isOnline () const
	Check if the client was initialized and not terminated.
template<class AMulticastAnswer , class ASocketAnswer >
int	poll (unsigned int timeout, AMulticastAnswer multicastAnswer, ASocketAnswer socketAnswer) const
	Poll both the multicast and the data socket until, either: More...
