I am a transport for bytes.

I represent (and wrap) the physical connection and synchronicity of the framework which is talking to the network. I make no representations about whether calls to me will happen immediately or require returning to a control loop, or whether they will happen in the same or another thread. Consider methods of this class (aside from getPeer) to be 'thrown over the wall', to happen at some indeterminate time.

Method	write	Write some data to the physical connection, in sequence, in a non-blocking fashion.
Method	writeSequence	Write a list of strings to the physical connection.
Method	loseConnection	Close my connection, after writing all pending data.
Method	getPeer	Get the remote address of this connection.
Method	getHost	Similar to getPeer, but returns an address describing this side of the connection.

def write(data): (source)

Write some data to the physical connection, in sequence, in a non-blocking fashion.

If possible, make sure that it is all written. No data will ever be lost, although (obviously) the connection may be closed before it all gets through.

def writeSequence(data): (source)

Write a list of strings to the physical connection.

If possible, make sure that all of the data is written to the socket at once, without first copying it all into a single string.

def loseConnection(): (source)

overridden in twisted.internet.interfaces.IProcessTransport

Close my connection, after writing all pending data.

Note that if there is a registered producer on a transport it will not be closed until the producer has been unregistered.

def getPeer(): (source)

overridden in twisted.internet.interfaces.ITCPTransport

Get the remote address of this connection.

Treat this method with caution. It is the unfortunate result of the CGI and Jabber standards, but should not be considered reliable for the usual host of reasons; port forwarding, proxying, firewalls, IP masquerading, etc.

Returns An IAddress provider.

def getHost(): (source)

overridden in twisted.internet.interfaces.ITCPTransport

Similar to getPeer, but returns an address describing this side of the connection.

Returns An IAddress provider.
