Detailed Description

template<class T>
class ext::smart_ptr< T >

Managed pointer simulating value like behavior.

The class is supposed to be similar to unique_ptr but allows copying of managed instance by clone method or its copy constructor.

Template Parameters

T	type of managed instance

Constructor & Destructor Documentation

smart_ptr() [1/5]

template<class T >

ext::smart_ptr< T >::smart_ptr ( )

inlineexplicit

Default initialization to null.

smart_ptr() [2/5]

template<class T >

ext::smart_ptr< T >::smart_ptr ( T *  data )

inlineexplicit

Constructor which takes ownership of the provided pointer.

smart_ptr() [3/5]

template<class T >

template<class R >

ext::smart_ptr< T >::smart_ptr ( smart_ptr< R >  other )

inline

Conversion constructor to simplify type casting.

Template Parameters

R	the type of the managed resource of the source smart pointer

Parameters

other

the source instance

smart_ptr() [4/5]

template<class T >

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

inline

Copy constructor of the smart pointer. Internally uses clone (if available) or copy constructor of the managed resource.

Parameters

other

the source instance

smart_ptr() [5/5]

template<class T >

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

inlinenoexcept

Move constructor of the smart pointer. Passes ownership of the managed resource from source to constructed instance.

Parameters

other

the source instance

~smart_ptr()

template<class T >

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

inlinenoexcept

The destructor of the shared pointer, responsible for freeing the managed resource.

Member Function Documentation

get() [1/2]

template<class T >

T * ext::smart_ptr< T >::get ( )

inline

Getter of the raw managed pointer.

Returns

the managed pointer

Here is the caller graph for this function:

get() [2/2]

template<class T >

T * ext::smart_ptr< T >::get ( ) const

inline

Getter of the raw managed pointer.

Returns

the managed pointer

operator bool()

template<class T >

ext::smart_ptr< T >::operator bool ( ) const

inlineexplicit

Tests the instance whether the managed pointer is valid.

Returns

true if the managed pointer is not null, false otherwise

operator*() [1/2]

template<class T >

T & ext::smart_ptr< T >::operator* ( )

inline

Operator dereference to access the inner managed pointer.

Returns

reference to managed data

operator*() [2/2]

template<class T >

T & ext::smart_ptr< T >::operator* ( ) const

inline

Operator dereference to access the inner managed pointer.

Returns

reference to managed data

operator->() [1/2]

template<class T >

T * ext::smart_ptr< T >::operator-> ( )

inline

Operator arrow to chain dereferece to inner managed pointer.

Returns

the managed pointer

operator->() [2/2]

template<class T >

T * ext::smart_ptr< T >::operator-> ( ) const

inline

Operator arrow to chain dereferece to inner managed pointer.

Returns

the managed pointer

operator=() [1/2]

template<class T >

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

inline

Copy operator of assignment. Internally uses clone (if available) or copy constructor of the managed resource.

Parameters

other

the source instance

Here is the call graph for this function:

operator=() [2/2]

template<class T >

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

inlinenoexcept

Copy operator of assignment. Passes ownership of the managed resource from source to this instance.

Parameters

other

the source instance

Here is the call graph for this function:

release()

template<class T >

T * ext::smart_ptr< T >::release ( )

inline

Releases the shared resource and returns it.

Returns

the released shared resource
