Inherited from _LogOwner:
| Method | logPrefix | Override this method to insert custom logging behavior. Its return value will be inserted in front of every line. It may be called more times than the number of output lines. |
| Method | _getLogPrefix | Determine the log prefix to use for messages related to
applicationObject, which may or may not be an interfaces.ILoggingContext
provider. |

Dispatch previously read data. Return True if self.reading and we don't have any more data
Indicates read connection was lost.
Override in a subclass to cause the reactor to monitor this selectable
for write events. This will be called once in
unregisterProducer if loseConnection has
previously been called, so that the connection can actually close.
Reliably write some data.
The data is buffered until his file descriptor is ready for writing.
Write a list of 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 string.
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.
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.
Stop consuming data.
This is called when a producer has lost its connection, to tell the consumer to go lose its connection (and break potential circular references).
Resume producing data.
This tells a producer to re-add itself to the main loop and produce more data for its consumer.
Pause producing data.
Tells a producer that it has produced too much data to process for the time being, and to stop until resumeProducing() is called.
Stop producing data.
This tells a producer that its consumer has died, so it must stop producing data for good.
