twisted.internet.endpoints._WrappingFactory : API documentation

_wrappedFactory =

A provider of IProtocolFactory whose buildProtocol method will be called and whose resulting protocol will be wrapped.

_onConnection =

An Deferred that fires when the protocol is connected

_connector =

A connector that is managing the current or previous connection attempt.

def __init__(self, wrappedFactory): (source)

Parameters wrappedFactory A provider of IProtocolFactory whose buildProtocol method will be called and whose resulting protocol will be wrapped.

def startedConnecting(self, connector): (source)

A connection attempt was started. Remember the connector which started said attempt, for use later.

def _canceller(self, deferred): (source)

The outgoing connection attempt was cancelled. Fail that Deferred with a error.ConnectingCancelledError.

Parameters	deferred	The `Deferred` that was cancelled; should be the same as `self._onConnection`. (type: `Deferred`)
Returns	`None`
Note	This relies on startedConnecting having been called, so it may seem as though there's a race condition where `_connector` may not have been set. However, using public APIs, this condition is impossible to catch, because a connection API (`connectTCP`/`SSL`/`UNIX`) is always invoked before a `_WrappingFactory`'s `Deferred` is returned to `connect()`'s caller.

def doStart(self): (source)

Start notifications are passed straight through to the wrapped factory.

def doStop(self): (source)

Stop notifications are passed straight through to the wrapped factory.

def buildProtocol(self, addr): (source)

Proxy buildProtocol to our self._wrappedFactory or errback the self._onConnection Deferred.

Returns An instance of _WrappingProtocol or None

def clientConnectionFailed(self, connector, reason): (source)

Errback the self._onConnection Deferred when the client connection fails.

Method	logPrefix	Describe this factory for log messages.
Method	startFactory	This will be called before I begin listening on a Port or Connector.
Method	stopFactory	This will be called before I stop listening on all Ports/Connectors.

Method	__init__
Method	startedConnecting	A connection attempt was started. Remember the connector which started said attempt, for use later.
Method	doStart	Start notifications are passed straight through to the wrapped factory.
Method	doStop	Stop notifications are passed straight through to the wrapped factory.
Method	buildProtocol	Proxy `buildProtocol` to our `self._wrappedFactory` or errback the `self._onConnection` `Deferred`.
Method	clientConnectionFailed	Errback the `self._onConnection` `Deferred` when the client connection fails.
Instance Variable	_wrappedFactory	A provider of IProtocolFactory whose buildProtocol method will be called and whose resulting protocol will be wrapped.
Instance Variable	_onConnection	An `Deferred` that fires when the protocol is connected
Instance Variable	_connector	A `connector` that is managing the current or previous connection attempt.
Method	_canceller	The outgoing connection attempt was cancelled. Fail that `Deferred` with a `error.ConnectingCancelledError`.
