Detailed Description

template<class T>
class ext::ptr_value< T >

Class representing wrapper of dynamically allocated object behaving like rvalue reference.

The class takes ownership of the dynamically allocated object

Template Parameters

the	type of value wrapped

Constructor & Destructor Documentation

ptr_value() [1/5]

template<class T >

ext::ptr_value< T >::ptr_value ( const T &  value )

inlineexplicit

Constructor of the ptr_value from dynaically allocated object. The class will take ownerhip of the pointer.

ptr_value() [2/5]

template<class T >

ext::ptr_value< T >::ptr_value ( T &&  value )

inlineexplicit

Constructor of the ptr_value from dynaically allocated object. The class will take ownerhip of the pointer.

ptr_value() [3/5]

template<class T >

template<class U >

ext::ptr_value< T >::ptr_value ( ptr_value< U > &&  other )

inline

User conversion constructor from ptr_value for type U where T is its predecessor.

Template Parameters

U	the subtype of T

Parameters

other

the other instance

ptr_value() [4/5]

template<class T >

ext::ptr_value< T >::ptr_value ( const ptr_value< T > &  other )

inline

Copy construction will clone the pointer referenced value in source instance to create new one for the constructed object.

Parameters

other

the other instance

ptr_value() [5/5]

template<class T >

ext::ptr_value< T >::ptr_value ( ptr_value< T > &&  other )

inlinenoexcept

Move construction will transfer ownership of the pointer from source instance to newly created one.

Parameters

other

the other instance

~ptr_value()

template<class T >

ext::ptr_value< T >::~ptr_value ( )

inlinenoexcept

Destructor will free the owned instance.

Member Function Documentation

get()

template<class T >

const T & ext::ptr_value< T >::get ( ) const

inline

Getter of the holded value.

Returns

constant reference to the holded value

operator const T &&()

template<class T >

ext::ptr_value< T >::operator const T && ( ) const &

inline

Allow automatic cast to const rvalue reference which can be itself binded to const reference.

The expected cast type const T & causes ambuguity in cast resolution, therefore a hack like this was found.

Returns

the holded value

operator T&()

template<class T >

ext::ptr_value< T >::operator T& ( ) &

inline

Allow automatic cast to const reference.

Returns

the holded value

operator T&&()

template<class T >

ext::ptr_value< T >::operator T&& ( ) &&

inline

Allow automatic cast to rvalue reference which can be itself binded to const reference.

Returns

the holded value

operator->() [1/3]

template<class T >

T * ext::ptr_value< T >::operator-> ( ) &

inline

Arrow operator to chain dereference.

Returns

the owned pointer

operator->() [2/3]

template<class T >

T * ext::ptr_value< T >::operator-> ( ) &&

inline

Arrow operator to chain dereference.

Returns

the owned pointer

operator->() [3/3]

template<class T >

const T * ext::ptr_value< T >::operator-> ( ) const &

inline

Arrow operator to chain dereference.

Returns

the owned pointer

operator=() [1/2]

template<class T >

ptr_value & ext::ptr_value< T >::operator= ( const ptr_value< T > &  other )

inline

Copy assignment will clone the pointer referenced value in source instance to create new one for the constructed object.

Parameters

other

the other instance

Here is the call graph for this function:

operator=() [2/2]

template<class T >

ptr_value & ext::ptr_value< T >::operator= ( ptr_value< T > &&  other )

inlinenoexcept

Parameters

Move	assignment will swap holded pointers between the two instances.
other	the other instance.
