Directory::Queue::Set(User Contributed Perl DocumentatDirectory::Queue::Set(3)NAMEDirectory::Queue::Set - object oriented interface to a set of
Directory::Queue objects
SYNOPSIS
use Directory::Queue;
use Directory::Queue::Set;
$dq1 = Directory::Queue->new(path => "/tmp/q1");
$dq2 = Directory::Queue->new(path => "/tmp/q2");
$dqset = Directory::Queue::Set->new($dq1, $dq2);
($dq, $elt) = $dqset->first();
while ($dq) {
# you can now process the element $elt of queue $dq...
($dq, $elt) = $dqset->next();
}
DESCRIPTION
This module can be used to put different queues into a set and browse
them as one queue. The elements from all queues are merged together and
sorted independently from the queue they belong to.
This works both with Directory::Queue::Normal and
Directory::Queue::Simple queues. Queues of different types can even be
mixed.
METHODS
The following methods are available:
new([DIRQ...])
return a new Directory::Queue::Set object containing the given
queue objects (class method)
add([DIRQ...])
add the given queue objects to the queue set; resetting the
iterator
remove([DIRQ...])
remove the given queue objects from the queue set; resetting the
iterator
first()
return the first (queue, element) couple in the queue set,
resetting the iterator; return an empty list if the queue is empty
next()
return the next (queue, element) couple in the queue set; return an
empty list if there is no next element
count()
return the total number of elements in all the queues of the set
