Description
UDPSocketReader is responsible for UDP socket I/O operations. When data or error is detected on a socket, the reader is invoked to do the I/O. After the data is read, it is passed on, to one of the handlers for processing. Errors are also passed to a handler for handling (if any configured). Depending on settings, data senders may be notified of the handler's data and error backlogs.

Constructors
UDPSocketReader 
UDPSocketReader(
typename UDPHandlerImpl < S >::List & handlers,
int backlogThreshold = 0
);
Creates the UDPSocketReader.
UDPSocketReader
UDPSocketReader(
typename UDPHandlerImpl < S >::List & handlers,
const UDPServerParams & serverParams
);
Creates the UDPSocketReader.
Destructor
~UDPSocketReader
~UDPSocketReader();
Destroys the UDPSocketReader.
Member Functions
handlerDone
bool handlerDone() const;
Returns true if all handlers are done processing data.
handlerStopped
bool handlerStopped() const;
Returns true if all handlers are stopped.
read
void read(
DatagramSocket & sock
);
Reads data from the socket and passes it to the next handler. Errors are also passed to the handler. If object is configured for replying to sender and data or error backlog threshold is exceeded, sender is notified of the current backlog size.
setError
AtomicCounter::ValueType setError(
int sock,
char * buf = 0,
const std::string & err = ""
);
Sets error to the provided buffer buf. If the buffer is null, a new buffer is obtained from handler. If successful, returns the handler's eror backlog size, otherwise returns zero.
stopHandler
void stopHandler();
Stops all handlers.
