Inherited from Logger:

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.

Undocumented
def writeToHandle(self, buff, evt): (source)
Undocumented
def write(self, data): (source)

Reliably write some data.

The data is buffered until his file descriptor is ready for writing.
def writeSequence(self, iovec): (source)

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.
def __init__(self, reactor=None): (source)
Undocumented
def connectionLost(self, reason): (source)

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.
def getFileHandle(self): (source)
Undocumented
def loseConnection(self, _connDone=failure.Failure(main.CONNECTION_DONE)): (source)

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.
def registerProducer(self, producer, streaming): (source)

Register to receive data from a producer.

This sets this selectable to be a consumer for a producer. When this selectable runs out of data on a write() call, it will ask the producer to resumeProducing(). A producer should implement the IProducer interface.

FileDescriptor provides some infrastructure for producer methods.
def unregisterProducer(self): (source)
Stop consuming data from a producer, without disconnecting.
def stopConsuming(self): (source)

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).
def resumeProducing(self): (source)
Undocumented
def pauseProducing(self): (source)
Undocumented
def stopProducing(self): (source)

Stop producing data.

This tells a producer that its consumer has died, so it must stop producing data for good.
