  2. Move assignment operator - Wikipedia

    en.wikipedia.org/wiki/Move_assignment_operator

    The move assignment operator, like most C++ operators, can be overloaded. Like the copy assignment operator it is a special member function . If the move assignment operator is not explicitly defined, the compiler generates an implicit move assignment operator ( C++11 and newer) provided that copy / move constructors , copy assignment operator ...

  3. Special member functions - Wikipedia

    en.wikipedia.org/wiki/Special_member_functions

    The automatically generated special member functions are: Default constructor if no other constructor is explicitly declared. Copy constructor if no move constructor and move assignment operator are explicitly declared. If a destructor is declared generation of a copy constructor is deprecated (C++11, proposal N3242 [2]).

  4. Copy constructor (C++) - Wikipedia

    en.wikipedia.org/wiki/Copy_constructor_(C++)

    In the C++ programming language, a copy constructor is a special constructor for creating a new object as a copy of an existing object. Copy constructors are the standard way of copying objects in C++, as opposed to cloning , and have C++-specific nuances.

  6. Constructor (object-oriented programming) - Wikipedia

    en.wikipedia.org/wiki/Constructor_(object...

    A Copy constructor has one formal parameter that is the type of the class (the parameter may be a reference to an object). It is used to create a copy of an existing object of the same class. Even though both classes are the same, it counts as a conversion constructor. While copy constructors are usually abbreviated copy ctor or cctor, they ...

  7. Copy elision - Wikipedia

    en.wikipedia.org/wiki/Copy_elision

    In C++ computer programming, copy elision refers to a compiler optimization technique that eliminates unnecessary copying of objects.. The C++ language standard generally allows implementations to perform any optimization, provided the resulting program's observable behavior is the same as if, i.e. pretending, the program were executed exactly as mandated by the standard.

  8. Object copying - Wikipedia

    en.wikipedia.org/wiki/Object_copying

    The resulting object is called an object copy or simply copy of the original object. Copying is basic but has subtleties and can have significant overhead. There are several ways to copy an object, most commonly by a copy constructor or cloning. Copying is done mostly so the copy can be modified or moved, or the current value preserved.

  9. Rule of three (C++ programming) - Wikipedia

    en.wikipedia.org/wiki/Rule_of_three_(C++...

    With the advent of C++11 the rule of three can be broadened to the rule of five (also known as "the rule of the big five" [5]) as C++11 implements move semantics, [6] allowing destination objects to grab (or steal) data from temporary objects. The following example also shows the new moving members: move constructor and move assignment operator.
