Detailed Description
template<class TYPE, bool IS_TRIVIALLY_DESTRUCTIBLE = bslstl::Optional_IsTriviallyDestructible<TYPE>::value>
struct bslstl::Optional_Data< TYPE, IS_TRIVIALLY_DESTRUCTIBLE >
This component-private struct manages a value_type object in optional by inheriting from `Optional_DataImp`. In addition, this primary template properly destroys the owned instance of TYPE in its destructor.
Constructor & Destructor Documentation
| bslstl::Optional_Data< TYPE, IS_TRIVIALLY_DESTRUCTIBLE >::~Optional_Data | ( | ) |
Destroy the managed value_type object, if it exists.

| TYPE& bslstl::Optional_DataImp< TYPE >::emplace | ( | bslma::Allocator * | allocator, | |
| BSLS_COMPILERFEATURES_FORWARD_REF(ARGS) | ... | |||
| ) | [inherited] |
Create an object of StoredType in d_buffer using the specified allocator and arguments and return a reference providing modifiable access to the underlying TYPE object.

| std::initializer_list< INIT_LIST_TYPE > | initializer_list, | |||
| BSLS_COMPILERFEATURES_FORWARD_REF(ARGS) | ... | |||
| ) | [inherited] |
Create an object of StoredType in d_buffer using the specified allocator, initializer_list and arguments, and return a reference providing modifiable access to the underlying TYPE object.
| void bslstl::Optional_DataImp< TYPE >::reset | ( | ) | [inherited] |
Destroy the value_type object in d_buffer, if any.
| TYPE& bslstl::Optional_DataImp< TYPE >::value | ( | ) | [inherited] |
Return the value_type object in d_buffer with const qualification adjusted to match that of TYPE. The behavior is undefined unless this->hasValue() == true.
| const TYPE& bslstl::Optional_DataImp< TYPE >::value | ( | ) | const [inherited] |
Return the value_type object in d_buffer with const qualification adjusted to match that of TYPE. The behavior is undefined unless this->hasValue() == true.
| bool bslstl::Optional_DataImp< TYPE >::hasValue | ( | ) | const [inherited] |
Return true if this objects has a value, and false otherwise.
