Method Details

connectionLost(self, reason)

The connection was lost.

This is called when the connection on a selectable object has been lost. It will be called whether the connection was closed explicitly, an exception occurred in an event handler, or the other end of the connection closed it first.

Clean up state here, but make sure to call back up to FileDescriptor.

Overrides:: twisted.internet.abstract.FileDescriptor.connectionLost (inherited documentation)

write(self, data)

Reliably write some data.

If there is no buffered data this tries to write this data immediately, otherwise this adds data to be written the next time this file descriptor is ready for writing.

Overrides:: twisted.internet.abstract.FileDescriptor.write (inherited documentation)
