Detailed Description

template<class Object>
class oglplus::OptionalImpl< tag::Object, Object >

Modifier that allows to create uninitialized Object(s)

The Optional template class is a modifier for Objects and in contrast to Objects it does allow to construct uninitialized instances which can be initialized later.

An Optional<Object> can be used everywhere an Object could be used, but it must be initialized (the IsInitialized() member function must return true), otherwise usage results in undefined behavior.

Constructor & Destructor Documentation

template<class Object >

oglplus::OptionalImpl< tag::Object, Object >::OptionalImpl

(

void

)

Construction of an uninitialized instance.

The only things that can safely be done with an uninitialized Optional<Object> is assignment, moving, destruction and checking whether it is initialized.

See Also

IsInitialized

Assign

template<class Object >

oglplus::OptionalImpl< tag::Object, Object >::OptionalImpl

(

Object &&

temp

)

Construction of an initialized instance.

Initialized Optional<Object> can be used everywhere where a plain Object could be used, furthermore Optional<Object> can also be cleared (this brings it in uninitialized state)

Member Function Documentation

template<class Object >

bool oglplus::OptionalImpl< tag::Object, Object >::IsInitialized

(

void

)

const

Returns true if the object is initialized, false otherwise.

The only things that can safely be done with an uninitialized Optional<Object> is assignment, moving, destruction and checking whether it is initialized. On the other hand initialized Optional<Object> can be used everywhere where a plain Object could be used.
