twisted.internet.epollreactor.EPollReactor : API documentation

A reactor that uses epoll(4).

Instance Variables	_poller	A `poll` which will be used to check for I/O readiness.
	_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.
	_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`.
	_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	__init__	Initialize epoll 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	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.
Method	doPoll	Poll the poller for new events.
Method	_add	Private method for adding a descriptor from the event loop.
Method	_remove	Private method for removing a descriptor from the event loop.
Method	_doReadOrWrite	fd is available for read or write, make the work and raise errors if necessary.
