twisted.internet.protocol.ClientCreator : API documentation

Client connections that do not require a factory.

The various connect* methods create a protocol instance using the given protocol class and arguments, and connect it, returning a Deferred of the resulting protocol instance.

Useful for cases when we don't really need a factory. Mainly this is when there is no shared state between protocol instances, and no need to reconnect.

The connectTCP, connectUNIX, and connectSSL methods each return a Deferred which will fire with an instance of the protocol class passed to ClientCreator.__init__. These Deferred can be cancelled to abort the connection attempt (in a very unlikely case, cancelling the Deferred may not prevent the protocol from being instantiated and connected to a transport; if this happens, it will be disconnected immediately afterwards and the Deferred will still errback with CancelledError).

def _connect(self, method, *args, **kwargs): (source)

Initiate a connection attempt.

Parameters	method	A callable which will actually start the connection attempt. For example, `reactor.connectTCP`.
	*args	Positional arguments to pass to `method`, excluding the factory.
	**kwargs	Keyword arguments to pass to `method`.
Returns	A `Deferred` which fires with an instance of the protocol class passed to this `ClientCreator`'s initializer or fails if the connection cannot be set up for some reason.

def connectTCP(self, host, port, timeout=30, bindAddress=None): (source)

Connect to a TCP server.

The parameters are all the same as to IReactorTCP.connectTCP except that the factory parameter is omitted.

Returns A Deferred which fires with an instance of the protocol class passed to this ClientCreator's initializer or fails if the connection cannot be set up for some reason.

def connectUNIX(self, address, timeout=30, checkPID=False): (source)

Connect to a Unix socket.

The parameters are all the same as to IReactorUNIX.connectUNIX except that the factory parameter is omitted.

Returns A Deferred which fires with an instance of the protocol class passed to this ClientCreator's initializer or fails if the connection cannot be set up for some reason.

def connectSSL(self, host, port, contextFactory, timeout=30, bindAddress=None): (source)

Connect to an SSL server.

The parameters are all the same as to IReactorSSL.connectSSL except that the factory parameter is omitted.

Returns A Deferred which fires with an instance of the protocol class passed to this ClientCreator's initializer or fails if the connection cannot be set up for some reason.

Method	__init__	Undocumented
Method	connectTCP	Connect to a TCP server.
Method	connectUNIX	Connect to a Unix socket.
Method	connectSSL	Connect to an SSL server.
Method	_connect	Initiate a connection attempt.
