How to build boost foreach cycle
- by Ockonal
Hi guys!
I have some abstract class called IClass (has pure virtual function). There are some classes which inherit IClass: CFirst, CSecond.
I want to add objects of classes which inherit into boost::ptr_vector:
class IClass { virtual void someFunc() = 0; };
class CFirst : public IClass { };
class CSecond : public IClass { };
boost::ptr_vector<IClass> objectsList;
objectsList.push_back(new CFirst());
objectsList.push_back(new CSecond());
And now my goal is to call function (which is declarated in IClass) from all objects in objectsList. I'd prefer to use BOOST_FOREACH:
foreach(IClass tempObj, objectsList)
{
tempObj.someFunc();
}
The problem is that IClass - abstract class, so I can't make instance of it for the foreach-cycle. What should I do?
