Callback Batch

callback-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 "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


### 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
