Method	connectionMade	Connection is made: reset internal state, and notify the controller.
Method	dataReceived	Called whenever data is received.
Method	query	Send out a message with the given queries.

Method	__init__	Undocumented
Method	pickID	Return a unique ID for queries.
Method	callLater	Wrapper around reactor.callLater, mainly for test purpose.
Method	_query	Send out a message with the given queries.
Method	_clearFailed	Clean the Deferred after a timeout.

Method

Make a connection to a transport and a server.

def writeMessage(self, message): (source)

Send a message holding DNS queries.

Parameters message (type: Message )

def connectionMade(self): (source)

from twisted.internet.interfaces.IProtocol

overrides twisted.internet.protocol.BaseProtocol.connectionMade

Connection is made: reset internal state, and notify the controller.

def dataReceived(self, data): (source)

from twisted.internet.interfaces.IProtocol

overrides twisted.internet.protocol.Protocol.dataReceived

Called whenever data is received.

Use this method to translate to a higher-level message. Usually, some callback will be made upon the receipt of each complete protocol message.

Parameters data a string of indeterminate length. Please keep in mind that you will probably need to buffer some data, as partial (or multiple) protocol messages may be received! I recommend that unit tests for protocols call through to this method with differing chunk sizes, down to one byte at a time.

def query(self, queries, timeout=60): (source)

Send out a message with the given queries.

Parameters	queries	The queries to transmit (type: `list` of `Query` instances )
Returns	(type: `Deferred` )
