NAME
Mojo::Reactor::Epoll - epoll backend for Mojo::Reactor
SYNOPSIS
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;DESCRIPTION
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.
EVENTS
Mojo::Reactor::Epoll inherits all events from Mojo::Reactor.
METHODS
Mojo::Reactor::Epoll 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.
