twisted.conch.telnet.TelnetTransport(Telnet, ProtocolTransportMixin) class documentation

Part of twisted.conch.telnet View Source (View In Hierarchy)
Instance Variable protocol An instance of the protocol to which this transport is connected, or None before the connection is established and after it is lost.
Instance Variable protocolFactory A callable which returns protocol instances which provide ITelnetProtocol. This will be invoked when a connection is established. It is passed *protocolArgs and **protocolKwArgs.
Instance Variable protocolArgs A tuple of additional arguments to pass to protocolFactory.
Instance Variable protocolKwArgs A dictionary of additional arguments to pass to protocolFactory.
Method __init__ Undocumented
Method connectionMade Called when a connection is made.
Method connectionLost Called when the connection is shut down.
Method enableLocal Reject all attempts to enable options.
Method enableRemote Reject all attempts to enable options.
Method disableLocal Signal a programming error by raising an exception.
Method disableRemote Signal a programming error by raising an exception.
Method unhandledSubnegotiation Called for subnegotiations for which no handler is installed.
Method unhandledCommand Called for commands for which no handler is installed.
Method applicationDataReceived Called with application-level data.
Method write Undocumented

Inherited from Telnet:

Instance Variable commandMap A mapping of bytes to callables. When a telnet command is received, the command byte (the first byte after IAC) is looked up in this dictionary. If a callable is found, it is invoked with the argument of the command, or None if the command takes no argument. Values should be added to this dictionary if commands wish to be handled. By default, only WILL, WONT, DO, and DONT are handled. These should not be overridden, as this class handles them correctly and provides an API for interacting with them.
Instance Variable negotiationMap A mapping of bytes to callables. When a subnegotiation command is received, the command byte (the first byte after SB) is looked up in this dictionary. If a callable is found, it is invoked with the argument of the subnegotiation. Values should be added to this dictionary if subnegotiations are to be handled. By default, no values are handled.
Instance Variable options A mapping of option bytes to their current state. This state is likely of little use to user code. Changes should not be made to it.
Instance Variable state A string indicating the current parse state. It can take on the values "data", "escaped", "command", "newline", "subnegotiation", and "subnegotiation-escaped". Changes should not be made to it.
Instance Variable transport This protocol's transport object.

Inherited from Protocol (via Telnet):

Method logPrefix Return a prefix matching the class name, to identify log messages related to this protocol instance.

Inherited from BaseProtocol (via Telnet, Protocol):

Method makeConnection Make a connection to a transport and a server.

Method getPeer Undocumented
protocol =
An instance of the protocol to which this transport is connected, or None before the connection is established and after it is lost.
protocolFactory =
A callable which returns protocol instances which provide ITelnetProtocol. This will be invoked when a connection is established. It is passed *protocolArgs and **protocolKwArgs.

Undocumented
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.conch.telnet.Telnet.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 enableLocal(self, option): (source)
overrides twisted.conch.telnet.Telnet.enableLocal

Reject all attempts to enable options.

def enableRemote(self, option): (source)
overrides twisted.conch.telnet.Telnet.enableRemote

Reject all attempts to enable options.

def disableLocal(self, option): (source)
overrides twisted.conch.telnet.Telnet.disableLocal

Signal a programming error by raising an exception.

enableLocal must return true for the given value of option in order for this method to be called. If a subclass of Telnet overrides enableLocal to allow certain options to be enabled, it must also override disableLocal to disable those options.

RaisesNotImplementedErrorAlways raised.
def disableRemote(self, option): (source)
overrides twisted.conch.telnet.Telnet.disableRemote

Signal a programming error by raising an exception.

enableRemote must return true for the given value of option in order for this method to be called. If a subclass of Telnet overrides enableRemote to allow certain options to be enabled, it must also override disableRemote tto disable those options.

RaisesNotImplementedErrorAlways raised.
def unhandledSubnegotiation(self, command, data): (source)
overrides twisted.conch.telnet.Telnet.unhandledSubnegotiation

Called for subnegotiations for which no handler is installed.

def unhandledCommand(self, command, argument): (source)
overrides twisted.conch.telnet.Telnet.unhandledCommand

Called for commands for which no handler is installed.

def applicationDataReceived(self, data): (source)
overrides twisted.conch.telnet.Telnet.applicationDataReceived

Called with application-level data.

def write(self, data): (source)
overrides twisted.conch.telnet.ProtocolTransportMixin.write
