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 an iterable of byte 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.|
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||The data to write. (type: |
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.
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.
