NAME
POE::Future
- use Future with POE
SYNOPSIS
use POE::Future;
my $future = POE::Future->new_delay( 10 )
->then_done( "Hello, world!" );
say $future->get;
DESCRIPTION
This subclass of Future integrates with POE, allowing the await
method to block until the future is ready. It allows POE
-using code to be written that returns Future
instances, so that it can make full use of Future
's abilities, including Future::Utils, and also that modules using it can provide a Future
-based asynchronous interface of their own.
For a full description on how to use Futures, see the Future documentation.
CONSTRUCTORS
new
$f = POE::Future->new;
Returns a new leaf future instance, which will allow waiting for its result to be made available, using the await
method.
new_delay
$f = POE::Future->new_delay( $after );
Returns a new leaf future instance which will become ready (with an empty result) after the specified delay time.
new_alarm
$f = POE::Future->new_alarm( $at );
Returns a new leaf future instance which will become ready (with an empty result) at the specified alarm time.
To create a delay or alarm timer that will fail instead of succeed, use the then_fail
method:
my $f = POE::Future->new_delay( 20 )
->then_fail( "Timeout" );
