Class t.i.e.EPollReactor(posixbase.PosixReactorBase):

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

Implements interfaces: twisted.internet.interfaces.IReactorFDSet

A reactor that uses epoll(4).
Instance Variables_pollerA poll which will be used to check for I/O readiness.
_selectablesA 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.
_readsA 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.
_writesA 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.

from twisted.internet.interfaces.IReactorFDSet
overrides twisted.internet.base.ReactorBase.removeWriter
Remove a Selectable for notification of data available to write.
def removeAll(self): (source)

from twisted.internet.interfaces.IReactorFDSet
overrides twisted.internet.base.ReactorBase.getReaders
Return the list of file descriptors currently monitored for input events by the reactor.
Returnsthe list of file descriptors monitored for input events. (type: list of IReadDescriptor )
def getWriters(self): (source)
from twisted.internet.interfaces.IReactorFDSet
overrides twisted.internet.base.ReactorBase.getWriters
Return the list file descriptors currently monitored for output events by the reactor.
Returnsthe list of file descriptors monitored for output events. (type: list of IWriteDescriptor )
def doPoll(self, timeout): (source)
Poll the poller for new events.
def _doReadOrWrite(self, selectable, fd, event): (source)
fd is available for read or write, make the work and raise errors if necessary.
