Replaces the managed object with the one managed byr.

If*this already owns an object and it is the lastshared_ptr owning it, andr is not the same as*this, the object is destroyed through the owned deleter.

1,2) Shares ownership of the object managed byr. Ifr manages no object,*this manages no object too. Equivalent toshared_ptr<T>(r).swap(*this).

3,4) Move-assigns ashared_ptr fromr. After the assignment,*this contains a copy of the previous state ofr, andr is empty. Equivalent toshared_ptr<T>(std::move(r)).swap(*this).

5) Transfers the ownership of the object managed byr to*this. Ifr manages no object,*this manages no object too. After the assignment,*this contains the pointer previously held byr, anduse_count()==1; alsor is empty. Equivalent toshared_ptr<T>(r).swap(*this).

6) Transfers the ownership of the object managed byr to*this. The deleter associated tor is stored for future deletion of the managed object.r manages no object after the call. Equivalent toshared_ptr<T>(std::move(r)).swap(*this).
