class DatagramGeneratorNet

Bases: DatagramGenerator, ConnectionReader, QueuedReturn< Datagram >

This class provides datagrams one-at-a-time as read directly from the net, via a TCP connection. If a datagram is not available, get_datagram() will block until one is.

explicit DatagramGeneratorNet(ConnectionManager *manager, int num_threads)

Creates a new DatagramGeneratorNet with the indicated number of threads to handle requests. Normally num_threads should be either 0 or 1 to guarantee that datagrams are generated in the same order in which they were received.

virtual bool get_datagram(Datagram &data)

Inherited from DatagramGenerator

Reads the next datagram from the stream. Blocks until a datagram is available. Returns true on success, false on stream closed or error.

virtual bool is_eof(void)

Returns true if the stream has been closed normally. This test may only be made after a call to get_datagram() has failed.

virtual bool is_error(void)

Returns true if the stream has an error condition.
