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.

POE::Component::Schedule METHODS

   spawn(Alias => name)
       Start up the PoCo::Schedule background session with the given alias. Returns the back-end
       session handle.

       No need to call this in normal use, "add()" and "new()" all crank one of these up if it is
       needed.

   add($session, $event_name, $iterator, @event_args)
           my $sched = POE::Component::Schedule->add(
               $session,
               $event_name,
               $DateTime_Set_iterator,
               @event_args
           );

       Add a set of events to the scheduler.

       Returns a schedule handle. The event is automatically deleted when the handle is not
       referenced anymore.

   new($session, $event_name, $iterator, @event_args)
       "new()" is an alias for "add()".

SCHEDULE HANDLE METHODS

   delete()
       Removes a schedule using the handle returned from "add()" or "new()".

       DEPRECATED: Schedules are now automatically deleted when they are not referenced anymore.
       So just setting the container variable to "undef" will delete the schedule.

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 orignal 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.
