Classes
		exceptions.Exception Error TOTException KnowsParent TimeoutTCPServer(SocketServer.TCPServer, KnowsParent) SocketServer.TCPServer(SocketServer.BaseServer) TimeoutTCPServer(SocketServer.TCPServer, KnowsParent)   class Error(exceptions.Exception)            __getitem__(...) from exceptions.Exception __init__(...) from exceptions.Exception __str__(...) from exceptions.Exception   class KnowsParent       Interface for storage/retrieval of reference to parent class.      __init__(self, parent) getParent(self) setParent(self, new)   class TOTException(exceptions.Exception)       Subclass of Exception for TimeoutTCPServer.      __getitem__(...) from exceptions.Exception __init__(self, text) __repr__ = __str__(self) __str__(self)   class TimeoutTCPServer(SocketServer.TCPServer, KnowsParent)       TCP SocketServer that starts in its own thread, and can be joined and stopped mid-course, with a maximum delay specified by the timeout. Also, it can be directed to only serve a specific number of requests before stopping (e.g.: 1).      __del__(self) __init__(self, port, timeout, handler, max_requests=0, parent=None) _abortServer(self) _badArgs(self, port, timeout, handler) _maxRequestsReached(self, n) _signalStarted(self) Signal that server thread has started _startServer(self) Start a server. This never returns, so needs to be started in its own thread. The caller should wait for the server_started.notify() before proceeding (see __init__). _waitStarted(self) Wait for server thread signal Pre: server_started lock has been acquire()d _waitingForData(self, ready) close(self) close_request(self, request) from SocketServer.TCPServer fileno(self) from SocketServer.TCPServer finish_request(self, request, client_address) from SocketServer.BaseServer getParent(self) from KnowsParent get_request(self) Get the request from the socket, with a timeout. If the server is closed during the select or accept, then shut down. handle_error(self, request, client_address) from SocketServer.BaseServer handle_request(self) from SocketServer.BaseServer process_request(self, request, client_address) from SocketServer.BaseServer serve_forever(self) Handle one request at a time until _doomsday. server_activate(self) from SocketServer.TCPServer server_bind(self) from SocketServer.TCPServer server_close(self) Close the listening socket and join the thread. setParent(self, new) from KnowsParent verify_request(self, request, client_address) from SocketServer.BaseServer

Functions
		select(...) select(rlist, wlist, xlist[, timeout]) -> (rlist, wlist, xlist)   Wait until one or more file descriptors are ready for some kind of I/O. The first three arguments are lists of file descriptors to be waited for: rlist -- wait until ready for reading wlist -- wait until ready for writing xlist -- wait for an ``exceptional condition'' If only one kind of condition is required, pass [] for the other lists. A file descriptor is either a socket or file object, or a small integer gotten from a fileno() method call on one of those.   The optional 4th argument specifies a timeout in seconds; it may be a floating point number to specify fractions of seconds.  If it is absent or None, the call will never time out.   The return value is a tuple of three lists corresponding to the first three arguments; each contains the subset of the corresponding file descriptors that are ready.   *** IMPORTANT NOTICE *** On Windows, only sockets are supported; on Unix, all file descriptors.
