NAME
Directory::Queue::Set - object oriented interface to a set of Directory::Queue objectsSYNOPSIS
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.METHODS
The following methods are available:- new([DIRQ...])
- return a new Directory::Queue::Set object containing the given Directory::Queue objects (class method)
- add([DIRQ...])
- add the given Directory::Queue objects to the queue set; resetting the iterator
- remove([DIRQ...])
- remove the given Directory::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
