Hello,
So far, I've been using:
template<typename T> struct storable : public boost::remove_const<typename boost::remove_reference<T>:
:type > {};
I've done the same for the same reason, but with the less inventive name remove_const_reference. FWIW, I would have appreciated something in type_traits to solve this more elegantly.
In my automata library, I defined a data_type metafunction that removes const, pointer, reference, volatile, and [] qualifiers from the input type.
Could you post the function here? Or would it be possible to eventually have it added to the type_traits library? Thanks, Christian On 17/04/07, Cromwell Enage <sponage@yahoo.com> wrote:

Hi,
Hello.
I am wondering if there is a construct in boost which, given a type T, returns the underlying "storable" type - say if T is int & the "storable_type" should be int. I'm not sure if the word "storable" is the best word...
I was thinking "data" type.
The scenario I am facing is making a function call that takes a parameter of type T, where I need to prepare the parameter before calling (specifically, deserializing it from an archive). Hence, as far as I can tell, I need to declare a variable of the underlying storable type, and get the right value inside it.
So far, I've been using:
template<typename T> struct storable : public boost::remove_const<typename boost::remove_reference<T>::type > {};
but I'm not sure if that cuts it in all situations.
In my automata library, I defined a data_type metafunction that removes const, pointer, reference, volatile, and [] qualifiers from the input type.
In any case, I figured the right thing might be in Boost already and I just haven't found it.
Any suggestions?
FWIW, I should be asking the same question. I'm curious myself.
