Re: [Boost-users] [mpl] SourceClass --> DestClass mapping

Hello,

This is kind of newbie question. Any help would be greatly appreciated :).

I'd like to map (SourceClass_i) list to (DestClass_i) list in the way that for any instance of SourceClass_i passed to the mapping expression, an instance of DestClass_i will be created and the result of the expression would be of type DestClass_i.

I defined the mapping as follows:

typedef mpl::map< mpl::pair, mpl::pair //, etc...

...

source2dest;

Now I guess I have to take the result of mpl::at and apply kind of:

template<typename DestClass> struct Creator { static DestClass create() { return *new DestClass; } };

...but unfortunately the things don't come together.

Thank you in advance!

How do you intend to use this. Creator::type>::create()? Can you be more specific about the problem. What you have ought to work (Almost. create should say return DestClass(), otherwise you have a memory leak) In Christ, Steven Watanabe
