io::async::loop::poll
IO::Async::Loop::Poll(3pm) User Contributed Perl Documentation IO::Async::Loop::Poll(3pm)
NAME
"IO::Async::Loop::Poll" - use "IO::Async" with "poll(2)"
SYNOPSIS
Normally an instance of this class would not be directly constructed by a program. It may however, be useful for runinng IO::Async with an
existing program already using an "IO::Poll" object.
use IO::Poll;
use IO::Async::Loop::Poll;
my $poll = IO::Poll->new;
my $loop = IO::Async::Loop::Poll->new( poll => $poll );
$loop->add( ... );
while(1) {
my $timeout = ...
my $ret = $poll->poll( $timeout );
$loop->post_poll;
}
DESCRIPTION
This subclass of "IO::Async::Loop" uses an "IO::Poll" object to perform read-ready and write-ready tests.
To integrate with existing code that uses an "IO::Poll", a "post_poll" can be called immediately after the "poll" method on the contained
"IO::Poll" object. The appropriate mask bits are maintained on the "IO::Poll" object when notifiers are added or removed from the set, or
when they change their "want_writeready" status. The "post_poll" method inspects the result bits and invokes the "on_read_ready" or
"on_write_ready" methods on the notifiers.
CONSTRUCTOR
$loop = IO::Async::Loop::Poll->new( %args )
This function returns a new instance of a "IO::Async::Loop::Poll" object. It takes the following named arguments:
"poll" The "IO::Poll" object to use for notification. Optional; if a value is not given, a new "IO::Poll" object will be constructed.
METHODS
$count = $loop->post_poll( $poll )
This method checks the returned event list from a "IO::Poll::poll" call, and calls any of the notification methods or callbacks that are
appropriate. It returns the total number of callbacks that were invoked; that is, the total number of "on_read_ready" and "on_write_ready"
callbacks for "watch_io", and "watch_time" event callbacks.
$poll Reference to the "IO::Poll" object
$count = $loop->loop_once( $timeout )
This method calls the "poll" method on the stored "IO::Poll" object, passing in the value of $timeout, and then runs the "post_poll" method
on itself. It returns the total number of callbacks invoked by the "post_poll" method, or "undef" if the underlying "poll" method returned
an error.
