mojo::reactor::poll
Mojo::Reactor::Poll(3pm) User Contributed Perl Documentation Mojo::Reactor::Poll(3pm)
NAME
Mojo::Reactor::Poll - Low level event reactor with poll support
SYNOPSIS
use Mojo::Reactor::Poll;
# Watch if handle becomes readable or writable
my $reactor = Mojo::Reactor::Poll->new;
$reactor->io($handle => sub {
my ($reactor, $writable) = @_;
say $writable ? 'Handle is writable' : 'Handle is readable';
});
# Add a timer
$reactor->timer(15 => sub {
my $reactor = shift;
$reactor->remove($handle);
say 'Timeout!';
});
# Start reactor if necessary
$reactor->start unless $reactor->is_running;
DESCRIPTION
Mojo::Reactor::Poll is a low level event reactor based on IO::Poll. Note that this reactor was designed for maximum portability, and
therefore does not use a monotonic clock to handle time jumps.
EVENTS
Mojo::Reactor::Poll inherits all events from Mojo::Reactor.
METHODS
Mojo::Reactor::Poll inherits all methods from Mojo::Reactor and implements the following new ones.
"io"
$reactor = $reactor->io($handle => sub {...});
Watch handle for I/O events, invoking the callback whenever handle becomes readable or writable.
"is_running"
my $success = $reactor->is_running;
Check if reactor is running.
"one_tick"
$reactor->one_tick;
Run reactor until an event occurs or no events are being watched anymore. Note that this method can recurse back into the reactor, so you
need to be careful.
"recurring"
my $id = $reactor->recurring(0.25 => sub {...});
Create a new recurring timer, invoking the callback repeatedly after a given amount of time in seconds.
"remove"
my $success = $reactor->remove($handle);
my $success = $reactor->remove($id);
Remove handle or timer.
"start"
$reactor->start;
Start watching for I/O and timer events, this will block until "stop" is called or no events are being watched anymore.
"stop"
$reactor->stop;
Stop watching for I/O and timer events.
"timer"
my $id = $reactor->timer(0.5 => sub {...});
Create a new timer, invoking the callback after a given amount of time in seconds.
"watch"
$reactor = $reactor->watch($handle, $readable, $writable);
Change I/O events to watch handle for with "true" and "false" values.
