A protocol that receives lines and/or raw data, depending on mode.

In line mode, each line that's received becomes a callback to lineReceived. In raw data mode, each chunk of raw data becomes a callback to LineReceiver.rawDataReceived. The setLineMode and setRawMode methods switch between the two modes.

This is useful for line-oriented protocols such as IRC, HTTP, POP, etc.

Class Variable delimiter The line-ending delimiter to use. By default this is b'\r\n'.
Class Variable MAX_LENGTH The maximum length of a line to allow (If a sent line is longer than this, the connection is dropped). Default is 16384.
Method clearLineBuffer Clear buffered data.
Method dataReceived Protocol.dataReceived. Translates bytes into lines, and calls lineReceived (or rawDataReceived, depending on mode.)
Method setLineMode Sets the line-mode of this receiver.
Method setRawMode Sets the raw mode of this receiver. Further data received will be sent to rawDataReceived rather than lineReceived.
Method rawDataReceived Override this for when raw data is received.
Method lineReceived Override this for when each line is received.
Method sendLine Sends a line to the other end of the connection.
Method lineLengthExceeded Called when the maximum line length has been reached. Override if it needs to be dealt with in some special way.

Inherited from Protocol:

Method logPrefix Return a prefix matching the class name, to identify log messages related to this protocol instance.
Method connectionLost Called when the connection is shut down.

Inherited from BaseProtocol (via Protocol):

Method makeConnection Make a connection to a transport and a server.
Method connectionMade Called when a connection is made.

Inherited from _PauseableMixin:

Method pauseProducing Undocumented
Method resumeProducing Undocumented
Method stopProducing Undocumented
delimiter =
The line-ending delimiter to use. By default this is b'\r\n'.
MAX_LENGTH =
The maximum length of a line to allow (If a sent line is longer than this, the connection is dropped). Default is 16384.
def clearLineBuffer(self): (source)

Clear buffered data.

ReturnsAll of the cleared buffered data. (type: bytes)
def dataReceived(self, data): (source)
def setLineMode(self, extra=''): (source)

Sets the line-mode of this receiver.

If you are calling this from a rawDataReceived callback, you can pass in extra unhandled data, and that data will be parsed for lines. Further data received will be sent to lineReceived rather than rawDataReceived.

Do not pass extra data if calling this function from within a lineReceived callback.

def setRawMode(self): (source)

Sets the raw mode of this receiver. Further data received will be sent to rawDataReceived rather than lineReceived.

def sendLine(self, line): (source)

Sends a line to the other end of the connection.

ParameterslineThe line to send, not including the delimiter. (type: bytes)
def lineLengthExceeded(self, line): (source)

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

The argument 'line' contains the remainder of the buffer, starting with (at least some part) of the line which is too long. This may be more than one line, or may be only the initial portion of the line.
