NAME¶

POE::Component::Schedule - Schedule POE events using DateTime::Set iterators

SYNOPSIS¶

    use POE qw(Component::Schedule);
    use DateTime::Set;
    POE::Session->create(
        inline_states => {
            _start => sub {
                $_[HEAP]{sched} = POE::Component::Schedule->add(
                    $_[SESSION], Tick => DateTime::Set->from_recurrence(
                        after      => DateTime->now,
                        before     => DateTime->now->add(seconds => 3),
                        recurrence => sub {
                            return $_[0]->truncate( to => 'second' )->add( seconds => 1 )
                        },
                    ),
                );
            },
            Tick => sub {
                print 'tick ', scalar localtime, "\n";
            },
            remove_sched => sub {
                # Three ways to remove a schedule
                # The first one is only for API compatibility with POE::Component::Cron
                $_[HEAP]{sched}->delete;
                $_[HEAP]{sched} = undef;
                delete $_[HEAP]{sched};
            },
            _stop => sub {
                print "_stop\n";
            },
        },
    );
    POE::Kernel->run();

DESCRIPTION¶

This component encapsulates a session that sends events to client sessions on a schedule as defined by a DateTime::Set iterator.

ACKNOWLEDGMENT & HISTORY¶

This module was a friendly fork of POE::Component::Cron to extract the generic parts and isolate the Cron specific code in order to reduce dependencies on other CPAN modules.

See <https://rt.cpan.org/Ticket/Display.html?id=44442>.

The original author of POE::Component::Cron is Chris Fedde.

POE::Component::Cron is now implemented as a class that inherits from POE::Component::Schedule.

Most of the POE::Component::Schedule internals have since been rewritten in 0.91_01 and we have now a complete test suite.
