True that I just need limited type supported and not entire universe of types, I have also seen following, but it would mean to put it in series of if(is_int), elseif(is_char_ptr) kind of statements, switch statement would be more cleaner, that why I thought type_traits may offer cleaner solution. Performance is also criteria. On 10/10/05, Christian Henning <chhenning@gmail.com> wrote:
I took a look at the examples in the Boost::Any documentation and found this:
bool is_int(const boost::any & operand) { return operand.type() == typeid(int); }
bool is_char_ptr(const boost::any & operand) { try { any_cast<const char *>(operand); return true; } catch(const boost::bad_any_cast &) { return false; } }
bool is_string(const boost::any & operand) { return any_cast<std::string>(&operand); }
Is that what you're looking for?
