Mojo::Reactor::Poll(3)

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;
  $reactor->io($first => sub {
    my ($reactor, $writable) = @_;
    say $writable ? 'First handle is writable' : 'First handle is readable';
  });

  # Change to watching only if handle becomes writable
  $reactor->watch($first, 0, 1);

  # Turn file descriptor into handle and watch if it becomes readable
  my $second = IO::Handle->new_from_fd($fd, 'r');
  $reactor->io($second => sub {
    my ($reactor, $writable) = @_;
    say $writable ? 'Second handle is writable' : 'Second handle is readable';
  })->watch($second, 1, 0);

  # Add a timer
  $reactor->timer(15 => sub {
    my $reactor = shift;
    $reactor->remove($first);
    $reactor->remove($second);
    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.

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.

  again
  $reactor->again($id);

Restart active timer.

  io
  $reactor = $reactor->io($handle => sub {...});

Watch handle for I/O events, invoking the callback whenever handle becomes readable or writable.

  is_running
  my $bool = $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 $bool = $reactor->remove($handle);
  my $bool = $reactor->remove($id);

Remove handle or timer.

  reset
  $reactor->reset;

Remove all handles and timers.

  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. Note that this method requires an active I/O watcher.
