bool
operator<(
ConstNullableValueRef<LHS_TYPE> const& lhs,
NullableValueRef<RHS_TYPE> const& rhs);Return true if the specified lhs nullable wrapper is ordered before the specified rhs nullable object, and false otherwise. lhs is ordered before rhs if lhs is null and rhs is non-null or if both are non-null and lhs.value() is ordered before rhs.value(). Note that this function will fail to compile if LHS_TYPE and RHS_TYPE are not compatible.
