Class Method Details

.add_minute ⇒ Object

adds a ball from the begining of the main queue to the minute track. Once the minute track is full the ball will drop to the five minute track triggering in reverse order the minute track to deposit to the main queue. When the five minute track is full it will pass the next ball from from the main queue to the hour track which triggers the five min track to drop its balls in reverse order to the main queue. When hour track is full will drop balls in reverse order to the main queue.

.run_ball_clock(balls, run_time) ⇒ Json

is provided it will calculate the days tell the que repeats.

Parameters:

  • runs (Fixnum, Fixnum) —

    clock with number of balls to start with and optionally a runtime.

Returns:

  • (Json) —

    json hash for min, five_min, hour and main queues. If no runtime
