i have a quick question about having a reference to a subset of a collection.
Consider i have a vector of objects. Now I want to create another vector which is a subset of this vector, and I dont want to create a copy of the subset of objects.
One of the ways I was thinking about is creating a vector<auto_ptr<MyClass> >. Is this a good approach?
Please suggest if you think any other containers or idioms or patterns would help in this case.
Thank you
No ! See : Why it is wrong to use std::auto_ptr<> with STL containers ?
Now, as an alternative, you could store raw pointers or
boost::shared_ptrdepending on your needs.
