Declared in `<bslstl_sharedptr.h>`

Make this weak pointer refer to the same object (if any) as the specified `rhs` weak pointer. Decrement the number of weak references to the object this weak pointer manages (if any), and increment the number of weak references to the object managed by `rhs` (if any). Return a reference providing modifiable access to this weak pointer. Note that if `rhs` is in an empty state, this weak pointer will be set to an empty state.

Make this weak pointer refer to the same object (if any) as the specified `rhs` (shared or weak) pointer to the (template parameter) `COMPATIBLE_TYPE`. Decrement the number of weak references to the object to which this weak pointer currently manages (if any), and increment the number of weak references to the object managed by `rhs` (if any). Return a reference providing modifiable access to this weak pointer. If `COMPATIBLE_TYPE *` is not implicitly convertible to `TYPE *`, then a compiler diagnostic will be emitted. Note that if `rhs` is in the empty state, this weak pointer will be set to the empty state.

Make this weak pointer refer to the same object (if any) as the specified `rhs` weak pointer of compatible type. Decrement the number of weak references to the object this weak pointer managed (if any), and reset `rhs` to an empty state. Return a reference providing modifiable access to this weak pointer. This function does not exist unless a pointer to (the template parameter) `COMPATIBLE_TYPE` is convertible to a pointer to (the template parameter) `ELEMENT_TYPE`. Note that if `rhs` is in an empty state, this weak pointer will be set to an empty state.
