twisted.internet.pollreactor.PollReactor(posixbase.PosixReactorBase, posixbase._PollLikeMixin) class documentation

Part of twisted.internet.pollreactor View Source (View In Hierarchy)

Implements interfaces: twisted.internet.interfaces.IReactorFDSet

A reactor that uses poll(2).

Method __init__ Initialize polling object, file descriptor tracking dictionaries, and the base class.
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 Selectable for notification of data available to read.
Method removeWriter Remove a Selectable for notification of data available to write.
Method removeAll Remove all selectables, and return a list of them.
Method doPoll Poll the poller for new events.
Method getReaders Return the list of file descriptors currently monitored for input events by the reactor.
Method getWriters Return the list file descriptors currently monitored for output events by the reactor.
Instance Variable _poller A select.poll which will be used to check for I/O readiness.
Instance Variable _selectables A dictionary mapping integer file descriptors to instances of FileDescriptor which have been registered with the reactor. All FileDescriptors which are currently receiving read or write readiness notifications will be present as values in this dictionary.
Instance Variable _reads A dictionary mapping integer file descriptors to arbitrary values (this is essentially a set). Keys in this dictionary will be registered with _poller for read readiness notifications which will be dispatched to the corresponding FileDescriptor instances in _selectables.
Instance Variable _writes A dictionary mapping integer file descriptors to arbitrary values (this is essentially a set). Keys in this dictionary will be registered with _poller for write readiness notifications which will be dispatched to the corresponding FileDescriptor instances in _selectables.
Method _updateRegistration Register/unregister an fd with the poller.
Method _dictRemove Undocumented
