synchronous iterator which will wait until all the jobs are done before returning. Unfortunately this means that you loose ability to choose concurrency on the fly (see iterator documentation in EM)
# File lib/em-synchrony/iterator.rb, line 12 def each(foreach=nil, after=nil, &blk) fiber = Fiber.current fe = (foreach || blk) cb = Proc.new do after.call if after fiber.resume end Fiber.yield super(fe, cb) end
# File lib/em-synchrony/iterator.rb, line 35 def inject(obj, foreach = nil, after = nil, &block) if foreach and after super(obj, foreach, after) else fiber = Fiber.current result = nil after = Proc.new {|res| result = res; fiber.resume} super(obj, block, after) Fiber.yield result end end
