| Method | _closeWriteConnection | Undocumented |
Create and bind my socket, and begin listening on it.
This is called on unserialization, and must be called after creating a server to begin listening on the specified port.| Parameters | datagram | The datagram to be sent.
(type: str
) |
| addr | A tuple of (stringified dotted-quad IP address, integer port
number); can be None in connected mode.
(type: tuple containing str as first element and
int as second element, or None
) |
Reliably write a sequence of data.
Currently, this is a convenience method roughly equivalent to:
for chunk in iovec:
fd.write(chunk)
It may have a more efficient implementation at a later time or in a different reactor.
As with thewrite() method, if a buffer size limit is
reached and a streaming producer is registered, it will be paused until the
buffered data is written to the underlying file descriptor.
Stop listening on this port.
If it does not complete immediately, will returnDeferred that
fires upon completion.
Close the connection at the next available opportunity.
Call this to cause this FileDescriptor to lose its connection. It will first write any data that it has buffered.
If there is data buffered yet to be written, this method will cause the transport to lose its connection as soon as it's done flushing its write buffer. If you have a producer registered, the connection won't be closed until the producer is finished. Therefore, make sure you unregister your producer when it's finished, or the connection will never close.Returns an IPv4Address.
This indicates the address from which I am connecting.
