Insert a value with a given priority

insert(mixed $datum, mixed $priority) : void
Inherited

Utilizes {@var $serial} to ensure that values of equal priority are emitted in the same order in which they are inserted.

inherited_from \Zend\Stdlib\SplPriorityQueue::insert()

Parameters

$datum

$priority

mixed

isEmpty()

isEmpty() 
Inherited

Remove a value from the queue
