Hi I have a phoenix expression of type actor< composite< divides_eval, vector< LambdaExp, composite< minus_eval, vector< argument<0>, value<double> > > > >
f_expr
with boost.lambda I could extract the different components (Lambda and the actual value stored by value<double>) from f_expr as: get<0>(f_expr.args) //for lambda and get<1>(get<1>(f_expr.args).args) //for lambda what is the equivalent for Boost.phoenix?, it seems that the phoenix actor doesn't have the member "args". something like at_c<1>(at_c<1>(f_expr)) seems to be in the right direction but it returns something of type value<double> from which I don't know how to extract the value in the same way at_c<1>(f_expr) returns the denominator, but it is not an actor, so it is not a lambda expression. the corresponding lambda type was: lambda_functor<lambda_functor_base< arithmetic_action<divide_action>, tuple< lambda_functor<// LambdaExp >,// lambda_functor<lambda_functor_base< arithmetic_action<minus_action>, tuple< lambda_functor< placeholder<1> >, double const // <-- attention adds const to avoid unreadable errors > > > >
f_expr
Thank you, Alfredo
