NAME

Mojo::Reactor::EV - Low-level event reactor with libev support

SYNOPSIS

  use Mojo::Reactor::EV;

  # Watch if handle becomes readable or writable
  my $reactor = Mojo::Reactor::EV->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::EV is a low-level event reactor based on EV (4.0+).

EVENTS

Mojo::Reactor::EV inherits all events from Mojo::Reactor::Poll.

METHODS

Mojo::Reactor::EV inherits all methods from Mojo::Reactor::Poll and implements the following new ones.

again

  $reactor->again($id);

Restart active timer.

is_running

  my $bool = $reactor->is_running;

Check if reactor is running.

new

  my $reactor = Mojo::Reactor::EV->new;

Construct a new Mojo::Reactor::EV object.

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.

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.
