PriorityQueue¶ ↑

A very simple priority queue.

pq = PriorityQueue.new
pq[5]  << 'foo'
pq[10] << 'unimportant foo'
pq[1]  << 'important foo'

pq.shift # => 'important foo'
pq.shift # => 'foo'
pq.shift # => 'unimportant foo'
pq.shift # => nil

PriorityQueue is also enumerable.

sudo gem install priority-queue -s http://gemcutter.org
