Ruote::Exp::ForgetExpression

Forgets all of its children.

This expression is somehow deprecated in favour of the :forget attribute that any expression understands.

sequence do
  participant 'alpha'
  forget do
    sequence do
      participant 'bravo'
      participant 'charly'
    end
  end
  participant 'delta'
end

In this example above, the flow goes from alpha to bravo and delta. The bravo-charly segment is independent of the main process flow. Charly's reply will be forgotten.

Now the equivalent process definition, but using the :forget attribute :

sequence do
  participant 'alpha'
  sequence :forget => true do
    participant 'bravo'
    participant 'charly'
  end
  participant 'delta'
end

This expression can be useful for fire-and-forget parallelism in processes.
