NAME
Dezi::Queue - simple in-memory FIFO queue class
SYNOPSIS
use Dezi::Queue;
my $queue = Dezi::Queue->new;
$queue->put( 'foo' );
$queue->size; # returns number of items in queue (1)
$queue->peek; # returns 'foo' (next value for get())
$queue->get; # returns 'foo' locks it in queue (no one else can get it)
$queue->remove('foo'); # returns 'foo' and removes it from queue
$queue->clean; # removes all completed items from queue
DESCRIPTION
Dezi::Queue is basically a Perl array, but it defines an API that can be implemented using any kind of storage and logic you want. One example would be a database that tracks items to be evaluated, or a flat file list.
METHODS
See Dezi::Class.
BUILD
