def connectionMade(self): (source)

from twisted.internet.interfaces.IProtocol

overrides twisted.internet.protocol.BaseProtocol.connectionMade

Called when a connection is made.

This may be considered the initializer of the protocol, because it is called when the connection is completed. For clients, this is called once the connection to the server has been established; for servers, this is called after an accept() call stops blocking and a socket has been received. If you need to send any greeting or initial message, do it here.

def connectionLost(self, reason): (source)

from twisted.internet.interfaces.IProtocol

overrides twisted.internet.protocol.Protocol.connectionLost

Called when the connection is shut down.

Clear any circular references here, and any external references to this Protocol. The connection has been closed.

def sendLine(self, line): (source)

Send a line to data channel.

Parameters line The line to be sent. (type: bytes)

def _formatOneListResponse(self, name, size, directory, permissions, hardlinks, modified, owner, group): (source)

Helper method to format one entry's info into a text entry like: 'drwxrwxrwx 0 user group 0 Jan 01 1970 filename.txt'

Parameters	name	`bytes` name of the entry (file or directory or link)
	size	`int` size of the entry
	directory	evals to `bool` - whether the entry is a directory
	permissions	`twisted.python.filepath.Permissions` object representing that entry's permissions
	hardlinks	`int` number of hardlinks
	modified	`float` - entry's last modified time in seconds since the epoch
	owner	`str` username of the owner
	group	`str` group name of the owner
Returns	`str` in the requisite format

def sendListResponse(self, name, response): (source)

Undocumented

def registerProducer(self, producer, streaming): (source)

from twisted.internet.interfaces.IConsumer

Register to receive data from a producer.

This sets self to be a consumer for a producer. When this object runs out of data (as when a send(2) call on a socket succeeds in moving the last data from a userspace buffer into a kernelspace buffer), it will ask the producer to resumeProducing().

For IPullProducer providers, resumeProducing will be called once each time data is required.

For IPushProducer providers, pauseProducing will be called whenever the write buffer fills up and resumeProducing will only be called when it empties.

Parameters	streaming	`True` if `producer` provides `IPushProducer`, `False` if `producer` provides `IPullProducer`. (type: `bool`)
Returns	`None`
Raises	RuntimeError	If a producer is already registered.

def unregisterProducer(self): (source)

from twisted.internet.interfaces.IConsumer

Stop consuming data from a producer, without disconnecting.

def write(self, data): (source)

from twisted.internet.interfaces.IConsumer

The producer will write data by calling this method.

The implementation must be non-blocking and perform whatever buffering is necessary. If the producer has provided enough data for now and it is a IPushProducer, the consumer may call its pauseProducing method.

def _conswrite(self, bytes): (source)

Undocumented

def dataReceived(self, bytes): (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.
