t.i.d.SelectReactor(posixbase.PosixReactorBase) : class documentation

Known subclasses: twisted.internet.gtkreactor.PortableGtkReactor

Implements interfaces: twisted.internet.interfaces.IReactorFDSet

A select() based reactor - runs on all POSIX platforms and on Win32.

Instance Variables	_reads	A dictionary mapping FileDescriptor instances to arbitrary values (this is essentially a set). Keys in this dictionary will be checked for read events.
	_writes	A dictionary mapping FileDescriptor instances to arbitrary values (this is essentially a set). Keys in this dictionary will be checked for writability.

Method	__init__	Initialize file descriptor tracking dictionaries and the base class.
Method	doSelect	Run one iteration of the I/O monitor loop.
Method	addReader	Add a FileDescriptor for notification of data available to read.
Method	addWriter	Add a FileDescriptor for notification of data available to write.
Method	removeReader	Remove a Selectable for notification of data available to read.
Method	removeWriter	Remove a Selectable for notification of data available to write.
Method	removeAll	Remove all readers and writers.
Method	getReaders	Return the list of file descriptors currently monitored for input events by the reactor.
Method	getWriters	Return the list file descriptors currently monitored for output events by the reactor.
Method	_preenDescriptors	Undocumented
Method	_doReadOrWrite	Undocumented

Inherited from PosixReactorBase:

Method	installWaker	Install a `waker' to allow threads and signals to wake up the IO thread.
Method	spawnProcess	Spawn a process, with a process protocol.
Method	listenUDP	Connects a given DatagramProtocol to the given numeric UDP port.
Method	listenMulticast	Connects a given DatagramProtocol to the given numeric UDP port.
Method	connectUNIX
Method	listenUNIX
Method	listenUNIXDatagram	Connects a given DatagramProtocol to the given path.
Method	connectUNIXDatagram	Connects a ConnectedDatagramProtocol instance to a path.
Method	listenTCP
Method	connectTCP
Method	connectSSL
Method	listenSSL
Method	listenWith	Undocumented
Method	connectWith	Undocumented
Method	_disconnectSelectable	Utility function for disconnecting a selectable.
Method	_handleSignals	Extend the basic signal handling logic to also support handling SIGCHLD to know when to try to reap child processes.
Method	_uninstallHandler	If a child waker was created and installed, uninstall it now.
Method	_removeAll	Remove all readers and writers, and list of removed IReadDescriptors and IWriteDescriptors.

Inherited from _SignalReactorMixin (via PosixReactorBase):

Method	startRunning	Extend the base implementation in order to remember whether signal handlers should be installed later.
Method	run	Undocumented
Method	mainLoop	Undocumented
Method	_reallyStartRunning	Extend the base implementation by also installing signal handlers, if self._installSignalHandlers is true.

Inherited from ReactorBase (via PosixReactorBase):

Method	wakeUp	Wake up the event loop.
Method	doIteration	Do one iteration over the readers and writers which have been added.
Method	resolve	Return a Deferred that will resolve a hostname.
Method	stop	See twisted.internet.interfaces.IReactorCore.stop.
Method	crash	See twisted.internet.interfaces.IReactorCore.crash.
Method	sigInt	Handle a SIGINT interrupt.
Method	sigBreak	Handle a SIGBREAK interrupt.
Method	sigTerm	Handle a SIGTERM interrupt.
