bsl::weak_ptr::operator=

Synopses

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.

weak_ptr&
operator=(weak_ptr const& rhs) noexcept;

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.

weak_ptr&
operator=(weak_ptr<COMPATIBLE_TYPE> const& rhs) noexcept
requires is_convertible<COMPATIBLE_TYPE *, ELEMENT_TYPE *>::value;

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.

template<class COMPATIBLE_TYPE>
weak_ptr&
operator=(weak_ptr<COMPATIBLE_TYPE>&& rhs) noexcept
requires is_convertible<COMPATIBLE_TYPE *, ELEMENT_TYPE *>::value;

Make this weak pointer refer to the same object (if any) as the specified rhs weak pointer. If rhs is not a reference to this weak pointer, 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. Note that if rhs is in an empty state, this weak pointer will be set to an empty state.
