thread::queue
Thread::Queue(3pm) Perl Programmers Reference Guide Thread::Queue(3pm)
NAME
Thread::Queue - thread-safe queues
SYNOPSIS
use Thread::Queue;
my $q = new Thread::Queue;
$q->enqueue("foo", "bar");
my $foo = $q->dequeue; # The "bar" is still in the queue.
my $foo = $q->dequeue_nb; # returns "bar", or undef if the queue was empty
my $left = $q->pending; # returns the number of items still in the queue
DESCRIPTION
A queue, as implemented by "Thread::Queue" is a thread-safe data structure much like a list. Any number of threads can safely add elements
to the end of the list, or remove elements from the head of the list. (Queues don't permit adding or removing elements from the middle of
the list).
FUNCTIONS AND METHODS
new The "new" function creates a new empty queue.
enqueue LIST
The "enqueue" method adds a list of scalars on to the end of the queue. The queue will grow as needed to accommodate the list.
dequeue The "dequeue" method removes a scalar from the head of the queue and returns it. If the queue is currently empty, "dequeue" will
block the thread until another thread "enqueue"s a scalar.
dequeue_nb
The "dequeue_nb" method, like the "dequeue" method, removes a scalar from the head of the queue and returns it. Unlike "dequeue",
though, "dequeue_nb" won't block if the queue is empty, instead returning "undef".
pending The "pending" method returns the number of items still in the queue.
