## Detailed Description

class mem_ui to keep a copy of a user_interaction object

this class is targeted for inheritance (it is advised to use a "protected" inheritance, not a "public" one). Instead of having all the stuf of managing, cloning, releasing a pointer on user_interaction a class simply put itslef as inherited from mem_ui to take the benefit of this implementation, once and for all. Use this class with caution espetially for class which will generate a ton of objects, as this will duplicate the user_interaction object in the same number. sometimes it is more efficient to have the user_interaction object as parameter of the constructor, using it if necessary while constructing the object only. In that situation, if the user_interaction is not need any further after construction, no need to make the class inherit from mem_ui.

## Constructor & Destructor Documentation

## ◆ mem_ui() [1/2]

libdar::mem_ui::mem_ui | ( | const std::shared_ptr< user_interaction > & | dialog | ) |

constructor

Parameters

  [in] | dialog | the user_interaction object to clone and store If you plan to use mem_ui, you should pass the user_interaction to its constructor for you later be able to call get_ui() at any time from the inherited class

## ◆ mem_ui() [2/2]

libdar::mem_ui::mem_ui | ( | const mem_ui & | ref | ) |
| default

the copy constructor

need to be called from the copy constructor of any inherited class that explicitely define one

## ◆ ~mem_ui()

virtual libdar::mem_ui::~mem_ui | ( |  | ) |
| inlinevirtual

destructor

it is declared as virtual, for precaution, as it may not be very frequent to release an object having just a mem_ui pointer on it.

## Member Function Documentation

## ◆ change_ui()

void libdar::mem_ui::change_ui | ( | const std::shared_ptr< user_interaction > & | new_dialog | ) |
| inlineprotected

change the user_interaction object

Definition at line 100 of file mem_ui.hpp.

## ◆ get_pointer()

std::shared_ptr< user_interaction > libdar::mem_ui::get_pointer | ( |  | ) | const
| inlineprotected

get access to the shared_ptr pointing to the user_interaction

Definition at line 97 of file mem_ui.hpp.

## ◆ get_ui()

user_interaction & libdar::mem_ui::get_ui | ( |  | ) | const
| inlineprotected

get access to the user_interaction object

Returns
  a reference to the clone object.

## ◆ operator=()

mem_ui & libdar::mem_ui::operator= | ( | const mem_ui & | ref | ) |
| default

assignement operator

you need to call it from the inherited class assignement operator if the inherited class explicitely defines its own one.
