node-handle(node-handle&& nh) noexcept;
Effects: Constructs a
node-handle object initializing
ptr_ with
nh.ptr_. Move constructs
alloc_ with
nh.alloc_.Assigns
nullptr to
nh.ptr_ and assigns
nullopt to
nh.alloc_.node-handle& operator=(node-handle&& nh);
Preconditions: Either
!alloc_, or
ator_traits::propagate_on_container_move_assignment::value
is
true, or
alloc_ == nh.alloc_. Effects: - If ptr_ != nullptr, destroys the value_type
subobject in the container_node_type object pointed to by ptr_
by calling ator_traits::destroy, then deallocates ptr_ by
calling ator_traits::template rebind_traits<container_node_type>::deallocate.
- Assigns nh.ptr_ to ptr_.
- If !alloc_ or ator_traits::propagate_on_container_move_assignment::value
is true,
move assigns nh.alloc_ to alloc_. - Assigns
nullptr to nh.ptr_ and assigns nullopt to
nh.alloc_.
