Hi,

Is boost::any suitable to use it as a type of field of record? Record is a set of fields. Every field may store value of different type: int, double, char*.

Usually, in this case I'd use union of int,double and char*. But I'd like to solve it a better way, more C++ than C.

So, would you recommend boost::any as a type of field value?

The boost::any class is more of a modern replacement for void * than it is for a discrete set of types which are usually placed in a union. Try boost::variant for the latter.

I understand it. I was hinted with Boost.Any by the example of property definition: name-value pair in the docs. It suggested me possible solution, something like: fieldname->fieldvalue. But I'm going to try Boost.Variant now. Cheers -- Mateusz Łoskot http://mateusz.loskot.net
