rg) BaseSelectorT a Selector abstract base class.
A selector supports registering file objects to be monitored for specific
I/O events.
A file object is a file descriptor or any object with a `fileno()` method.
An arbitrary object can be attached to the file object, which can be used
for example to store context information, a callback, etc.
A selector can use various implementations (select(), poll(), epoll()...)
depending on the platform. The default `Selector` class uses the most
efficient implementation on the current platform.
Nc [ e)a Register a file object.
Parameters:
fileobj -- file object or file descriptor
events -- events to monitor (bitwise mask of EVENT_READ|EVENT_WRITE)
data -- attached data
Returns:
SelectorKey instance
Raises:
ValueError if events is invalid
KeyError if fileobj is already registered
OSError if fileobj is closed or otherwise is unacceptable to
the underlying system call (if a system call is made)
Note:
OSError may or may not be raised
NotImplementedErrorr r r r s r registerBaseSelector.registerc s
* "!r# c [ e)a Unregister a file object.
Parameters:
fileobj -- file object or file descriptor
Returns:
SelectorKey instance
Raises:
KeyError if fileobj is not registered
Note:
If fileobj is registered but has since been closed this does
*not* raise OSError (even if the wrapped syscall does)

Parameters:

Raises:

}}Wd33r# c [ e)a Perform the actual selection, until some monitored file objects are
ready or a timeout expires.
Parameters:
timeout -- if timeout > 0, this specifies the maximum wait time, in
seconds
if timeout <= 0, the select() call won't block, and will
report the currently ready file objects
if timeout is None, select() will block until a monitored
file object becomes ready
Returns:
list of (key, events) for ready file objects
`events` is a bitwise mask of EVENT_READ|EVENT_WRITE

This wraps _fileobj_to_fd() to do an exhaustive search in case
the object is invalid but we still have it in our map. This
is used by unregister() so we can unregister an object that
was previously registered even if it is closed. It is also
used by _SelectorMapping.
