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';
  });

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

  # 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.

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