t.i.e._ContinuousPolling(posixbase._PollLikeMixin, posixbase._DisconnectSelectableMixin) : class documentation

Part of twisted.internet.epollreactor View Source View In Hierarchy

Implements interfaces: twisted.internet.interfaces.IReactorFDSet

Schedule reads and writes based on the passage of time, rather than notification.

This is useful for supporting polling filesystem files, which epoll(7) does not support.

The implementation uses posixbase._PollLikeMixin, which is a bit hacky, but re-implementing and testing the relevant code yet again is unappealing.

Method __init__ Undocumented
Method iterate Call doRead and doWrite on all readers and writers respectively.
Method addReader Add a FileDescriptor for notification of data available to read.
Method addWriter Add a FileDescriptor for notification of data available to write.
Method removeReader Remove a FileDescriptor from notification of data available to read.
Method removeWriter Remove a FileDescriptor from notification of data available to write.
Method removeAll Remove all readers and writers.
Method getReaders Return a list of the readers.
Method getWriters Return a list of the writers.
Instance Variable _reactor The EPollReactor that is using this instance.
Instance Variable _loop A LoopingCall that drives the polling, or None.
Instance Variable _readers A set of FileDescriptor objects that should be read from.
Instance Variable _writers A set of FileDescriptor objects that should be written to.
Method _checkLoop Start or stop a LoopingCall based on whether there are readers and writers.

Inherited from _PollLikeMixin:

Method _doReadOrWrite fd is available for read or write, do the work and raise errors if necessary.

Inherited from _DisconnectSelectableMixin:

Method _disconnectSelectable Utility function for disconnecting a selectable.
_reactor =

_loop =
A LoopingCall that drives the polling, or None.
_readers =
A set of FileDescriptor objects that should be read from.
_writers =
A set of FileDescriptor objects that should be written to.
