Mojo::Reactor::Poll - Low-level event reactor with poll support
SYNOPSIS
my $reactor = Mojo::Reactor::Poll->new;
$reactor ->io( $first => sub {
my ( $reactor , $writable ) = @_ ;
say $writable ? 'First handle is writable' : 'First handle is readable' ;
});
$reactor ->watch( $first , 0, 1);
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);
$reactor ->timer( 15 => sub {
my $reactor = shift ;
$reactor ->remove( $first );
$reactor ->remove( $second );
say 'Timeout!' ;
});
$reactor ->start unless $reactor ->is_running;

DESCRIPTION
Mojo::Reactor::Poll is a low-level event reactor based on IO::Poll.
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.
again
Restart timer. Note that this method requires an active timer.
io
$reactor = $reactor ->io( $handle => sub {...});
|
Watch handle for I/O events, invoking the callback whenever handle becomes readable or writable.
$reactor ->io( $handle => sub {
my ( $reactor , $writable ) = @_ ;
say $writable ? 'Handle is writable' : 'Handle is readable' ;
});
|
is_running
my $bool = $reactor ->is_running;
|
Check if reactor is running.
next_tick
my $undef = $reactor ->next_tick( sub {...});
|
Execute callback as soon as possible, but not before returning or other callbacks that have been registered with this method, always returns undef
.
one_tick
Run reactor until an event occurs or no events are being watched anymore.
my $id = $reactor ->timer(0. 5 => sub {});
$reactor ->one_tick;
$reactor ->remove( $id );
|
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
Remove all handles and timers.
start
Start watching for I/O and timer events, this will block until "stop" is called or no events are being watched anymore.
$reactor ->start unless $reactor ->is_running;
|
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.
$reactor ->watch( $handle , 1, 0);
$reactor ->watch( $handle , 0, 1);
$reactor ->watch( $handle , 1, 1);
$reactor ->watch( $handle , 0, 0);
