I found the solution to my question, it was not in shared_ptr but instead every associative container had to be modified with a template argument functor that does lessthan. On Tue, 24 Feb 2009 23:58 -0500, "V S P" wrote:

I am trying to use shared_ptr in std::set and std::vector. For std::set I was expecting that when I define a less than comparasing operation in my class (wrapped by shared ptr) -- it would actually get invoked.

Instead I think it is the less than of the shared_ptr that is being invoked So I do not get the ordering I expect in my std::set container.

Therefore wanted to ask -- how can it be done, that the operator.< of my class and not the shared_ptr's is being used by std::set

I searched for posting on this subject but did not come up with the solution. Only discussions about the details of pointer comparasing
