Method Details

_handleSigchld(self, signum, frame)

Reap all processes on SIGCHLD.

This gets called on SIGCHLD. We do no processing inside a signal handler, as the calls we make here could occur between any two python bytecode instructions. Deferring processing to the next eventloop round prevents us from violating the state constraints of arbitrary classes. Note that a Reactor must be able to accept callLater calls at any time, even interleaved inside it's own methods; it must block SIGCHLD if it is unable to guarantee this.

_handleSignals(self)

Install the signal handlers for the Twisted event loop.

connectMulticast(self, remotehost, remoteport, protocol, localport=0, interface='', maxPacketSize=8192)

Connects a ConnectedDatagramProtocol instance to a UDP port.

EXPERIMENTAL.

connectSSL(self, host, port, factory, contextFactory, timeout=30, bindAddress=None)

See Also: twisted.internet.interfaces.IReactorSSL.connectSSL

connectTCP(self, host, port, factory, timeout=30, bindAddress=None)

See Also: twisted.internet.interfaces.IReactorTCP.connectTCP

connectUDP(self, remotehost, remoteport, protocol, localport=0, interface='', maxPacketSize=8192)

DEPRECATED.

Connects a ConnectedDatagramProtocol instance to a UDP port.

connectUNIX(self, address, factory, timeout=30, checkPID=0)

See Also: twisted.internet.interfaces.IReactorUNIX.connectUNIX

connectUNIXDatagram(self, address, protocol, maxPacketSize=8192, mode=438, bindAddress=None)

Connects a ConnectedDatagramProtocol instance to a path.

EXPERIMENTAL.

installWaker(self)

Install a `waker' to allow threads and signals to wake up the IO thread.

We use the self-pipe trick (http://cr.yp.to/docs/selfpipe.html) to wake the reactor. On Windows we use a pair of sockets.
Overrides:
twisted.internet.base.ReactorBase.installWaker

listenMulticast(self, port, protocol, interface='', maxPacketSize=8192)

Connects a given DatagramProtocol to the given numeric UDP port.

EXPERIMENTAL.
Returns:
object conforming to IListeningPort.

listenSSL(self, port, factory, contextFactory, backlog=5, interface='')

See Also: twisted.internet.interfaces.IReactorSSL.listenSSL

listenTCP(self, port, factory, backlog=5, interface='')

See Also: twisted.internet.interfaces.IReactorTCP.listenTCP

listenUDP(self, port, protocol, interface='', maxPacketSize=8192)

Connects a given DatagramProtocol to the given numeric UDP port.

EXPERIMENTAL.
Returns:
object conforming to IListeningPort.

listenUNIX(self, address, factory, backlog=5, mode=438, wantPID=0)

See Also: twisted.internet.interfaces.IReactorUNIX.listenUNIX

listenUNIXDatagram(self, address, protocol, maxPacketSize=8192, mode=438)

Connects a given DatagramProtocol to the given path.

EXPERIMENTAL.
Returns:
object conforming to IListeningPort.
