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.
