                          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.

`str` | `delimiter`: The line-ending delimiter to use.
`int` | `line_mode` = 1
`int` | `MAX_LENGTH`: The maximum length of a line to allow (If a sent line is longer than this, the connection is dropped).

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)

Class Variable Details

    ### acceptRequests Type: `int` Value:
        1

    ### acceptResponses Type: `int` Value:
        1

    ### debug Type: `int` Value:
        0

    ### state Type: `str` Value:
        'firstline'

    ### version Type: `str` Value:
        'SIP/2.0'
