Specialized connection over a ZMQ socket.
Definition: ZMQConnection.h:63
Input connection allowing to speak with non-zmq sockets via a ZMQ_STREAM socket.
unsigned int m_maximalBufferSize
Parameter for the maximal buffer size. If this size is reached, a FATAL will be issued.
size_t m_writeAddress
Where in the buffer are we currently writing to.
std::vector< char > m_buffer
Internal storage for the buffer.
unsigned int m_currentSize
How large should the full message be? The information is from the first int of the message.
bool m_receiveEventMessages
Parameter to receive event messages (see above)
void clear()
Reset the internal buffer and counter.
std::vector< zmq::message_t > handleIncomingData()
Block until a TCP packet can be received from the socket.
std::string m_inputIdentity
Internal storage of the connected socket to check if we get messages from multiple ones.
Output connection to speak to non-zmq sockets via a ZMQ_STREAM socket.
bool m_addEventSize
Parameter to add the event size to a message.
void handleIncomingData()
Handle incoming data: a socket (dis)connect.
virtual void handleEvent(zmq::message_t message)
Pass on the message - maybe by prefixing it with a htonl-converted data size in bytes.
bool isReady() const final
If no socket is connected, this connection is not ready.
std::string m_dataIdentity
Internal storage of the connected identity to no have multiple connections.
Abstract base class for different kinds of events.
