Mojo::Reactor::Epoll - epoll backend for Mojo::Reactor
use Mojo::Reactor::Epoll; # Watch if handle becomes readable or writable my $reactor = Mojo::Reactor::Epoll->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; # Or in an application using Mojo::IOLoop BEGIN { $ENV{MOJO_REACTOR} = 'Mojo::Reactor::Epoll' } use Mojo::IOLoop;
Mojo::Reactor::Epoll is an event reactor for Mojo::IOLoop that uses the epoll(7) Linux subsystem. The usage is exactly the same as other Mojo::Reactor implementations such as Mojo::Reactor::Poll. To set it as the default backend for Mojo::IOLoop, set the MOJO_REACTOR environment variable to Mojo::Reactor::Epoll. This must be set before Mojo::IOLoop is loaded.

MOJO_REACTOR
Mojo::Reactor::Epoll
Mojo::Reactor::Epoll inherits all events from Mojo::Reactor.
Mojo::Reactor::Epoll inherits all methods from Mojo::Reactor and implements the following new ones.
$reactor->again($id);
Restart active timer.
$reactor = $reactor->io($handle => sub {...});
Watch handle for I/O events, invoking the callback whenever handle becomes readable or writable.
my $bool = $reactor->is_running;
Check if reactor is running.
$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.
my $id = $reactor->recurring(0.25 => sub {...});
Create a new recurring timer, invoking the callback repeatedly after a given amount of time in seconds.
my $bool = $reactor->remove($handle); my $bool = $reactor->remove($id);
Remove handle or timer.
$reactor->reset;
Remove all handles and timers.
$reactor->start;
Start watching for I/O and timer events, this will block until "stop" is called or no events are being watched anymore.
$reactor->stop;
Stop watching for I/O and timer events.
my $id = $reactor->timer(0.5 => sub {...});
Create a new timer, invoking the callback after a given amount of time in seconds.
$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.
Report any issues on the public bugtracker.
