                      MessagesParser

A SIP messages parser.

Expects dataReceived, dataDone repeatedly, in that order. Shouldn't be connected to actual transport.

Method Summary
	`__init__(self, messageReceivedCallback)`
	`dataDone(self)`
	`dataReceived(self, data)` Protocol.dataReceived.
	`handleFirstLine(self, line)` Expected to create self.message.
	`invalidMessage(self)`
	`lineLengthExceeded(self, line)` Called when the maximum line length has been reached.
	`lineReceived(self, line)` Override this for when each line is received.
	`messageDone(self, remainingData)`
	`rawDataReceived(self, data)` Override this for when raw data is received.
	`reset(self, remainingData)`
Inherited from LineReceiver
	`clearLineBuffer(self)` Clear buffered data.
	`sendLine(self, line)` Sends a line to the other end of the connection.
	`setLineMode(self, extra)` Sets the line-mode of this receiver.
	`setRawMode(self)` Sets the raw mode of this receiver.
Inherited from Protocol
	`connectionFailed(self)` (Deprecated)
	`connectionLost(self, reason)` Called when the connection is shut down.
Inherited from BaseProtocol
	`connectionMade(self)` Called when a connection is made.
	`makeConnection(self, transport)` Make a connection to a transport and a server.

Method Details

dataReceived(self, data)

Protocol.dataReceived. Translates bytes into lines, and calls lineReceived (or rawDataReceived, depending on mode.)

Overrides:: twisted.protocols.basic.LineReceiver.dataReceived (inherited documentation)

handleFirstLine(self, line)

Expected to create self.message.

lineLengthExceeded(self, line)

Called when the maximum line length has been reached. Override if it needs to be dealt with in some special way.

Overrides:: twisted.protocols.basic.LineReceiver.lineLengthExceeded (inherited documentation)

lineReceived(self, line)

Override this for when each line is received.

Overrides:: twisted.protocols.basic.LineReceiver.lineReceived (inherited documentation)

rawDataReceived(self, data)

Override this for when raw data is received.

Overrides:: twisted.protocols.basic.LineReceiver.rawDataReceived (inherited documentation)
