| 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 | clearBuffer | Undocumented |
| Method | loseConnection | Close my connection, after writing all pending data. |
| 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 | registerProducer | Register to receive data from a producer. |
| Method | unregisterProducer | Stop consuming data from a producer, without disconnecting. |
| Method | logPrefix | Undocumented |
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. |
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 | iovec | Undocumented |
| data | The data to write. |
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.
Similar to getPeer, but returns an address describing this side of the connection.
| Returns | An IAddress provider. | |
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. | |
Register to receive data from a producer.
This sets self to be a consumer for a producer. When this object runs out of data (as when a send(2) call on a socket succeeds in moving the last data from a userspace buffer into a kernelspace buffer), it will ask the producer to resumeProducing().
For IPullProducer providers, resumeProducing will be called once each time data is required.
For IPushProducer providers, pauseProducing will be called whenever the write buffer fills up and resumeProducing will only be called when it empties. The consumer will only call resumeProducing to balance a previous pauseProducing call; the producer is assumed to start in an un-paused state.
| Parameters | producer | Undocumented |
| streaming | True if producer provides IPushProducer, False if producer provides IPullProducer. | |
| Raises | RuntimeError | If a producer is already registered. |
