em-batch provides ability to run more callbacked methods of single or more objects by elegant, readable and transparent way in a linear sequence, so subsequently in single batch.
Two classes are available, sequencer and more general batch. Batch supports more objects in one batch, sequencer is syntactic sugar in fact for single object.
See some trivial examples:
require "eventmachine" require "callback-batch" class Foo def foo1 yield :foo1 end def foo2 yield :foo2 end end class Bar def bar1 yield :bar1 end def bar2 yield :bar2 end end EM::run do ### Sequencer s = CallbackSequencer::new(Foo::new) s.foo1 s.foo2 s.execute do # now will be both methods executed p s.results # will contain [:foo1, :foo2] end ### Batch s = CallbackBatch::new f = Foo::new b = Bar::new s.take(f).foo1 s.take(b).bar2 s.execute do # now will be both methods executed p s.results # will contain [:foo1, :bar2] end end
