19 * ClientBuf represents two buffered I/O channels, input and output. Each
20 * is stored in its own Bu::QueueBuf. One side is client oriented and can
21 * have filters applied ala Bu::StreamStack. The other is server oriented
22 * and is accesesed raw. Both must be accessed via accessor objects.
23 *
24 * Direct access to the buffers isn't allowed, instead you must select a
25 * perspective. client() provides an accessor where reading consumes data
26 * coming from the socket and writing provides data to write to the socket.
27 * server() works in reverse, writing is writing data from the socket that
28 * we have just read, reading is reading data that should be written to the
29 * socket.
30 *
31 * client() provides a filtered access view of the data, while server() is
32 * unfiltered.

34 * Core of a network server. This class is distinct from a ServerSocket in
35 * that a ServerSocket is one listening socket, nothing more. Socket will
36 * manage a pool of both ServerSockets and connected Sockets along with
37 * their protocols and buffers.
38 *
39 * To start serving on a new port, use the addPort functions. Each call to
40 * addPort creates a new ServerSocket, starts it listening, and adds it to
41 * the server pool.
42 *
43 * All of the real work is done by scan, which will wait for up
44 * to the timeout set by setTimeout before returning if there is no data
45 * pending. scan should probably be called in some sort of tight
46 * loop, possibly in it's own thread, or in the main control loop.
47 *
48 * In order to use a Server you must subclass it and implement the pure
49 * virtual functions. These allow you to receive notification of events
50 * happening within the server itself, and actually makes it useful.
