twisted.names.client.DNSClientFactory : API documentation

Method	__init__	Undocumented
Instance Variable	controller	Undocumented
Instance Variable	timeout	Undocumented
Method	clientConnectionLost	Called when an established connection is lost.
Method	clientConnectionFailed	Fail all pending TCP DNS queries if the TCP connection attempt fails.
Method	buildProtocol	Create an instance of a subclass of Protocol.

Inherited from ClientFactory:

Method

Called when a connection has been started.

Inherited from Factory (via ClientFactory):

Class Variable	protocol	Undocumented
Instance Variable	numPorts	Undocumented
Class Variable	noisy	Undocumented
Class Method	forProtocol	Create a factory for the given protocol.
Method	logPrefix	Describe this factory for log messages.
Method	doStart	Make sure startFactory is called.
Method	doStop	Make sure stopFactory is called.
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.

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

Called when an established connection is lost.

It may be useful to call connector.connect() - this will reconnect.

Parameters	connector	Undocumented
	reason	Undocumented (type: `twisted.python.failure.Failure`)

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

Fail all pending TCP DNS queries if the TCP connection attempt fails.

Parameters	connector	Not used. (type: `twisted.internet.interfaces.IConnector`)
	reason	A `Failure` containing information about the cause of the connection failure. This will be passed as the argument to `errback` on every pending TCP query `deferred`. (type: `twisted.python.failure.Failure`)

def buildProtocol(self, addr): (source)

Create an instance of a subclass of Protocol.

The returned instance will handle input on an incoming server connection, and an attribute "factory" pointing to the creating factory.

Alternatively, None may be returned to immediately close the new connection.

Override this method to alter how Protocol instances get created.

Parameters addr an object implementing twisted.internet.interfaces.IAddress
