NAME

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

SYNOPSIS

use POE qw(Component::Schedule);
use DateTime::Set;

$s1 = POE::Session->create(
    inline_states => {
        _start => sub {
            $_[KERNEL]->delay( _die_, 120 );
        },

        Tick => sub {
            print 'tick ', scalar localtime, "\n";
        },

        Tock => sub {
            print 'tock ', scalar localtime, "\n";
        },

        _die_ => sub {
            print "_die_";
        },
    },
);

# crontab DateTime set the hard way
$sched1 = POE::Component::Schedule->add(
    $s1 => Tick => DateTime::Set->from_recurrence(
        after      => DateTime->now,
        recurrence => sub {
            return $_[0]->truncate( to => 'second' )->add( seconds => 2 )
        },
    ),
);

# delete some schedule of events
$sched1->delete();

DESCRIPTION

This component encapsulates a session that sends events to client sessions on a schedule as defined by a DateTime::Set iterator. The implementation is straight forward if a little limited.

POE::Component::Schedule METHODS

spawn(Alias => name)

No need to call this in normal use, add() and new() all crank one of these up if it is needed. Start up a PoCo::Schedule. Returns a handle that can then be added to.

add

Add a set of events to the schedule. the session and event name are passed to POE without even checking to see if they are valid and so have the same warnings as ->post() itself. Returns a schedule handle that can be used to remove the event.

$schedule->add(
    $session,
    $event_name,
    $DateTime_Set_iterator,
    @event_args
);

new

new is an alias for add

SCHEDULE HANDLE METHODS

delete

Removes a schedule using the handle returned from ->add or ->new
