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 getHost Similar to getPeer, but returns an address describing this side of the connection.
Method getPeer Get the remote address of this connection.
Method loseConnection Close my connection, after writing all pending data.
Method write Write some data to the physical connection, in sequence, in a non-blocking fashion.
Method writeSequence Write an iterable of byte strings to the physical connection.
def getHost(): (source)
Similar to getPeer, but returns an address describing this side of the connection.
Returns
IAddressAn IAddress provider.
def getPeer(): (source)

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
IAddressAn IAddress provider.
def loseConnection(): (source)

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 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.

Parameters
data:bytesThe data to write.
def writeSequence(data): (source)

Write an iterable of byte 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 byte string.

Parameters
data:Iterable[bytes]The data to write.
