handles a new incoming connection






Returns:
true for positive result of handling, false for negative result of handling
Throws:
IOException - if some other I/O error occurs. Throwing this exception causes that the underlying connection will be closed.
BufferUnderflowException - if more incoming data is required to process (e.g. delimiter hasn't yet received -> readByDelimiter methods or size of the available, received data is smaller than the required size -> readByLength). The BufferUnderflowException will be swallowed by the framework
MaxReadSizeExceededException - if the max read size has been reached (e.g. by calling method IDataSource.readStringByDelimiter(String, int)).
                                      Throwing this exception causes that the underlying connection will be closed.
