Remove from a std::set<shared_ptr<T>> by T*
- by Autopulated
I have a set of shared pointers:
std::set<boost::shared_ptr<T>> set;
And a pointer:
T* p;
I would like to efficiently remove the element of set equal to p, but I can't do this with any of the members of set, or any of the standard algorithms, since T* is a completely different type to boost::shared_ptr<T>.
A few approaches I can think of are:
somehow constructing a new shared_ptr from the pointer that won't take ownership of the pointed to memory (ideal solution, but I can't see how to do this)
wrapping / re-implementing shared_ptr so that I can do the above
just doing my own binary search over the set
Help!
