[cdi-dev] Vetoed with Expression

[Otávio Gonçalves de Santana]

In CDI we have the Vetoed annotation[1] that vetoes the class, but we can't
use expression to represent exclude this class.  This feature would useful
to many things, for example, an internationalization of payment[2] or just
have a class that should not run when is in production. In Delta Spike[3],
already there are this improvement.

public interface Payment {
void pay();
}

@Vetoed(onExpression = "instance eq brazil", interpretedBy =
PaymentInterpreter.class)
class BrazilianPayment implements Payment {
...
}

@Vetoed(onExpression = "instance eq mexico", interpretedBy =
PaymentInterpreter.class)
class MexicanPayment implements Payment {
...
}
