Inherited from Protocol:

Method logPrefix Return a prefix matching the class name, to identify log messages related to this protocol instance.
Method dataReceived Called whenever data is received.
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.
def getCharacter(self, x, y): (source)
Undocumented
def connectionMade(self): (source)
from twisted.internet.interfaces.IProtocol
overrides twisted.internet.protocol.BaseProtocol.connectionMade
overridden in twisted.conch.insults.helper.ExpectableBuffer

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 write(self, data): (source)
from twisted.internet.interfaces.ITransport
overridden in twisted.conch.insults.helper.ExpectableBuffer

Add the given printable bytes to the terminal.

Line feeds in bytes will be replaced with carriage return / line feed pairs.

def _currentFormattingState(self): (source)
Undocumented
def insertAtCursor(self, b): (source)

Add one byte to the terminal at the cursor and make consequent state updates.

If b is a carriage return, move the cursor to the beginning of the current row.

If b is a line feed, move the cursor to the next row or scroll down if the cursor is already in the last row.

Otherwise, if b is printable, put it at the cursor position (inserting or overwriting as dictated by the current mode) and move the cursor.

def _emptyLine(self, width): (source)
