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