    DispatchQueue

    DispatchQueue is a simple way to serialize jobs.
    It was done for crawling things, but could be used in any case that you need to do more than one work at a time.

    COMPATIBILITY

    Check build status to see support in different platforms

    USAGE

    • The threaded_way:
    [1,2,3].threaded_each{|i|
      sleep 4-i
      puts i
    }
    
    3
    2
    1
    
    [1,2,3].threaded_map{|i| sleep 4-i ; i } #=> [3,2,1]
    
    • The explicit way:
    my_work_queue = DispatchQueue.new(lambda{ sleep 3 ; 5},  lambda{ 10 })
    my_work_queue.sort #=> [5, 10]
    
    • The implicit way:
    DQ[ lambda{ sleep 5 ; 3} , Proc.new{ sleep 6; 2 } ].sort #=> [2,3]
    

    CHANGELOG

    • 1.1.0 Create [].threaded_each [].threaded_map (2011/09/22)
    • 1.0.5 Reduce implementation
