Detailed Description
template<class t_TYPE, class = void>
struct bsl::Is_Empty_Imp< t_TYPE, class >
Private class: do not use outside of bslmf_isempty component. This meta-function provides an initial dispatch that always derives from false_type unless the template parameter t_TYPE is a class type, as only class types can be empty. The following partial specialization forwards all class types to a final test. This two-phase dispatch is necessary as some types, such as void and function types, cannot be passed to a sizeof operator that is used to implement the next stage of matching.
