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.

NAME

       Mojo::IOLoop::Delay - Synchronize events

SYNOPSIS

	 use Mojo::IOLoop::Delay;

	 # Synchronize multiple events
	 my $delay = Mojo::IOLoop::Delay->new;
	 $delay->on(finish => sub { say 'BOOM!' });
	 for my $i (1 .. 10) {
	   $delay->begin;
	   Mojo::IOLoop->timer($i => sub {
	     say 10 - $i;
	     $delay->end;
	   });
	 }

	 # Wait for events if necessary
	 $delay->wait unless Mojo::IOLoop->is_running;

DESCRIPTION

       Mojo::IOLoop::Delay synchronizes events for Mojo::IOLoop.

EVENTS

       Mojo::IOLoop::Delay can emit the following events.

   "finish"
	 $delay->on(finish => sub {
	   my $delay = shift;
	   ...
	 });

       Emitted safely once the active event counter reaches zero.

ATTRIBUTES

       Mojo::IOLoop::Delay implements the following attributes.

   "ioloop"
	 my $ioloop = $delay->ioloop;
	 $delay     = $delay->ioloop(Mojo::IOLoop->new);

       Loop object to control, defaults to the global Mojo::IOLoop singleton.

METHODS

       Mojo::IOLoop::Delay inherits all methods from Mojo::EventEmitter and implements the following new ones.

   "begin"
	 my $cb = $delay->begin;

       Increment active event counter, the returned callback can be used instead of "end".

	 my $delay = Mojo::IOLoop->delay;
	 Mojo::UserAgent->new->get('mojolicio.us' => $delay->begin);
	 my $tx = $delay->wait;

   "end"
	 $delay->end;
	 $delay->end(@args);

       Decrement active event counter.

   "wait"
	 my @args = $delay->wait;

       Start "ioloop" and stop it again once the "finish" event gets emitted, only works when "ioloop" is not running already.

	 # Use the "finish" event to synchronize portably
	 $delay->on(finish => sub {
	   my ($delay, @args) = @_;
	   ...
	 });
	 $delay->wait unless $delay->ioloop->is_running;
