class TimeSequenceGenerator

The +new+ class method initiliazes the class

== Parameters

 * _referencetime = point in time from which sequence starts

min = minimum lenght in seconds from n-th time to n+1-th* time

max = maximum length in second rom n-th time to n+1-th* time

#

== Example

t = TimeSequenceGenerator.new(Time.now, 60, 100)

def initialize(reference_time = Time.now, min = 1, max = 100) @min_period = min @max_period = max @times = [] generate(reference_time, @min_period, @max_period) end

Returns next time in sequence

== Example

t = TimeSequenceGenerator.new(Time.utc(2000,"jan",1,20,15,1), 1, 100)

t.next #=> 2000-01-01 20:15:21 UTC

# def next if @times.size == 1 generate(@reference_time, @min_period, @max_period) @times.shift elsif @times.size == 0 begin sleep(0.00000001) end until @times.size > 0 @times.shift else @times.shift end end

private

Quietly in the background fills the array containing time sequence

def generate(reference, min, max, n = 100) Thread.new do diff = max - min n.times do |i| reference = reference + min + rand(diff) @times << reference end @reference_time = @times.last end end end
