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 ( )

inlinevirtualnoexcept

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.

Definition at line 87 of file mem_ui.hpp.

Member Function Documentation

◆ 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.
