hello,
i have something like this:
*hpp :
namespace tag{
template<typename Id>
struct sequence{
static ::boost::parameter::keyword<
a_<Id> >& a;
static ::boost::parameter::keyword<
b_<Id> >& b;
static ::boost::parameter::keyword<
arg_method_<Id> >& arg_method;
};
}
namespace sequence_arg{
struct method{};
struct a:public method{};
struct b:public method{};
}
class sequence{
public:
template
sequence(const Id& id,const ArgPack&args){
fill_elements(id,args,args[tag::sequence<Id>::arg_method]);
}
private:
template
void fill_elements(
const Id& id,
const ArgPack& args,
sequence_arg::a method
);
template
void fill_elements(
const Id& id,
const ArgPack& args,
sequence_arg::b method
);
};
*.cpp :
sequence seq(
id(),
(
tag::sequence::a = a_value,
tag::sequence::arg_method = sequence_arg::a()
)
);
So far so good except there is redundancy of information about which
method to use, so I'm looking for a way to be able to call say
sequence seq(
id(),
(
tag::sequence::a = a_value
)
)
Any suggestion?
