Labrador::Common::URLAlloc

SYNOPSIS

    use Labrador::Common::URLAlloc;
    use Labrador::Common::URLAlloc::Delay;
    my $urlalloc = Labrador::Common::URLAlloc::new(
        'Labrador::Common::URLAlloc::Delay',
        $data, $urlstates, $config);
    $urlalloc->new_url('http://www.gla.ac.uk/#');
    print $urlalloc->get_url();

DESCRIPTION

Central URL queueing class, though it must be implemented. Examples of child classes are Delay, BFS, DFS.

NB: This class is abstract, and must be implemented by a child class.

METHODS

new($data, $urlstates, $config, @params)
init()
new_urls(@urls): Maps to new_url for each @url.
new_url($url): ABSTRACT: Must be implemented by a child class.
update_average()
last_average()
get_url(): Dequeue one URL
get_urls($count): Dequeue upto $count URLs.
empty_queues: Empties all the queues.
next(): In Delay URLAlloc modules, returns number of seconds until next URL is ready,
queue_size(): Returns the number of URLs queued.
delay_urls(%urls): Delay the URLs in the keys of %urls by the amount of seconds in values of %urls. Only URLAlloc implementations that implement delay handling will actually delay the URLs. Other implemetation will just enqueue the URLs to the back of the queues.
