event_utils¶ ↑

EventUtils is meant to provide modules and classes to help building services on top of EventMachine without having to cope with some of the mechnics of eventmachine itself.

the first implemented facility is EventUtils::DeferredLoop

it makes possible to perform action on groups of deferrable objects in an intuitive way, and without having to take care of starting/stopping the EventMachine reactor

example:

d1 and d2 are two deferrables
and we want to compare them but the comparaison is only feasible when
d1 and d2 have both deferred status set.

In this case the code will look like

require 'event_utils'
include EventUtils

in_deferred_loop do
  waiting_for d1, d2 do
    d1 > d2
  end
end
