class Win32Reactor(posixbase.PosixReactorBase): (source)
Implements interfaces: twisted.internet.interfaces.IReactorFDSet
, twisted.internet.interfaces.IReactorWin32Events
Reactor that uses Win32 event APIs.
Method | __init__ |
Undocumented |
Method | add |
Add a new win32 event to the event loop. |
Method | add |
Add a socket FileDescriptor for notification of data available to read. |
Method | add |
Add a socket FileDescriptor for notification of data available to write. |
Method | do |
Undocumented |
Method | get |
Return the list of file descriptors currently monitored for input events by the reactor. |
Method | get |
Return the list file descriptors currently monitored for output events by the reactor. |
Method | remove |
Remove all selectables, and return a list of them. |
Method | remove |
Remove an event. |
Method | remove |
Remove a Selectable for notification of data available to read. |
Method | remove |
Remove a Selectable for notification of data available to write. |
Class Variable | dummy |
Undocumented |
Method | _make |
Make a win32 event object for a socket. |
Method | _run |
Undocumented |
Method | _run |
Undocumented |
Instance Variable | _closed |
These descriptors have had close notification delivered from the OS, but are not marked as allowed to handle read events in the reactor. They are saved here to record their closed state, but not processed at all... |
Instance Variable | _closed |
Along with _closedAndNotReading, keeps track of descriptors which have had close notification delivered from the OS but which we have not finished reading data from. MsgWaitForMultipleObjects will only deliver close notification to us once, so we remember it in these two dictionaries until we're ready to act on it... |
Instance Variable | _events |
A dictionary mapping win32 event object to tuples of FileDescriptor instances and event masks. |
Instance Variable | _reads |
A dictionary mapping FileDescriptor instances to a win32 event object used to check for read events for that descriptor. |
Instance Variable | _writes |
A dictionary mapping FileDescriptor instances to a arbitrary value. Keys in this dictionary will be given a chance to write out their data. |

Undocumented |
Method | start |
Extend the base implementation in order to remember whether signal handlers should be installed later. |
Method | _really |
Extend the base implementation by also installing signal handlers, if self._installSignalHandlers is true. |
Instance Variable | _install |
A flag which indicates whether any signal handlers will be installed during startup. This includes handlers for SIGCHLD to monitor child processes, and SIGINT, SIGTERM, and SIGBREAK to stop the reactor. |

These descriptors have had close notification delivered from the OS, but are not marked as allowed to handle read events in the reactor. They are saved here to record their closed state, but not processed at all. When one of these descriptors is passed to IReactorFDSet.addReader
, it is moved out of this dictionary and into _closedAndReading. The descriptors are keys in this dictionary. The values are arbitrary. This is a weak key dictionary so that if an application tells the reactor to stop reading from a descriptor and then forgets about that descriptor itself, the reactor will also forget about it.
Along with _closedAndNotReading, keeps track of descriptors which have had close notification delivered from the OS but which we have not finished reading data from. MsgWaitForMultipleObjects will only deliver close notification to us once, so we remember it in these two dictionaries until we're ready to act on it. The OS has delivered close notification for each descriptor in this dictionary, and the descriptors are marked as allowed to handle read events in the reactor, so they can be processed. When a descriptor is marked as not allowed to handle read events in the reactor (ie, it is passed to IReactorFDSet.removeReader
), it is moved out of this dictionary and into _closedAndNotReading. The descriptors are keys in this dictionary. The values are arbitrary.
