Hi,
I've got some code which needs to call a template function on different
objects (potentially in a for loop). I'm currently doing this using an
array of function ptrs but like the idea of an array of types.
template<class T>
bool func( std::string& id )
{
return T::dothing( id );
}
int main()
{
const int countOfTypes = 3;
boost::function< bool (std::string& )> funcs[countOfTypes] =
{ boost::bind( func<Obj1>, _1
),
boost::bind( func<Obj2>, _1
),
boost::bind( func<Obj3>, _1
) };
for( int i = 0; i < countOfTypes; ++i )
{
funcs[i]( "testid" );
//would prefer
//func( "testid" );
}
}
I believe this should be possible using the pre-processor or meta
programming parts of boost but have no experience of either and was
hoping for some pointers. Is it possible and is it, IYO, better than the
function pointer method I'm currently using?
Thanks in advance,
Patrick
