Constructors
Declared in <bdlb_nullablevalueref.h>
Create a nullable object wrapper that refers to the target object of the specified original wrapper. Note that the created wrapper does not own a copy of the underlying nullable value, but instead refers to it, and so the lifetime of the target must exceed the lifetime of the created wrapper.
NullableValueRef(NullableValueRef const& original);Create a nullable object wrapper that refers to the specified opt object. Note that the created wrapper does not own a copy of the underlying nullable value, but instead refers to it, and so the lifetime of opt must exceed the lifetime of the created wrapper.
NullableValueRef(NullableAllocatedValue<TYPE>& opt);Create a nullable object wrapper that refers to the specified opt object. Note that the created wrapper does not own a copy of the underlying nullable value, but instead refers to it, and so the lifetime of opt must exceed the lifetime of the created wrapper.
NullableValueRef(bsl::optional<TYPE>& opt);
