NAME Array::Queue::Priority - A custom sorted queue VERSION version 0.1.2 SYNOPSIS my $queue = Array::Queue::Priority->new( sort_cb => sub { $_[0]->{last_name} cmp $_[1]->{last_name} }); $ar->add({ last_name => 'Rogers' }); $ar->add({ last_name => 'Stark' }); $ar->add({ last_name => 'Banner' }); while ($node = $queue->first) { # do things with node $queue->remove; } DESCRIPTION Array::Queue::Priority priority queue, sorted by whatever you desire. As values are inserted, they are sorted on the fly, ensuring the values come out in the order you desire. You simply supply the sort_cb at the time of construction. If no sort_cb is supplied, it will try to sort by values passed. You'll probably get warnings if that's just a string, and who knows what you will get if it's a hashref. Straight numbers will work just find though. Call first() then remove() for a little "transactional safety" if there's an error processing the first item in the queue. Inherits from Array::Queue. METHODS add $ar->add( 99 ); You can add any type of item to the queue. remove $ar->remove; Remove the oldest item on the queue. Returns value removed. first $ar->first; Returns the first / oldest item in the queue. Leaves the item in the queue. queue $ar->queue; Reference directly the array used to store the queued items. size $ar->size; How many elements are in the queue. empty $ar->empty; Boolean, is queue empty?
