Method Details

__init__(self, port, proto, interface='', maxPacketSize=8192, reactor=None)
(Constructor)

Initialize with a numeric port to listen on.

connectionLost(self, reason=None)

Cleans up my socket.

doRead(self)

Called when my socket is ready for reading.

getHost(self)

Returns a tuple of ('INET_UDP', hostname, port), indicating the servers address

logPrefix(self)

Returns the name of my class, to prefix log entries with.

loseConnection(self)

Stop accepting connections on this port.

This will shut down my socket and call self.connectionLost().

startListening(self)

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.

stopListening(self)

Stop accepting connections on this port.

This will shut down my socket and call self.connectionLost().

write(self, datagram, (host,

Write a datagram.
