  2. Smart pointer - Wikipedia

    en.wikipedia.org/wiki/Smart_pointer

    Smart pointers typically keep track of the memory they point to, and may also be used to manage other resources, such as network connections and file handles. Smart pointers were first popularized in the programming language C++ during the first half of the 1990s as rebuttal to criticisms of C++'s lack of automatic garbage collection. [1] [2]

  3. Reference (C++) - Wikipedia

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

    In the C++ programming language, a reference is a simple reference datatype that is less powerful but safer than the pointer type inherited from C. The name C++ reference may cause confusion, as in computer science a reference is a general concept datatype, with pointers and C++ references being specific reference datatype implementations.

  4. Reference counting - Wikipedia

    en.wikipedia.org/wiki/Reference_counting

    Objects that are shared but not owned can be accessed via a reference, raw pointer, or iterator (a conceptual generalisation of pointers). However, by the same token, C++ provides native ways for users to opt-into such functionality: C++11 provides reference counted smart pointers, via the std::shared_ptr class, enabling automatic shared memory ...

  5. Component Object Model - Wikipedia

    en.wikipedia.org/wiki/Component_Object_Model

    In C++, a smart pointer can be used to automate reference count management. The following are guidelines for when to AddRef and Release should called: A functions that returns an interface reference (via return value or via "out" parameter) increments the count of the returned object

  6. Garbage collection (computer science) - Wikipedia

    en.wikipedia.org/wiki/Garbage_collection...

    Reference counting in C++ is usually implemented using "smart pointers" [18] whose constructors, destructors, and assignment operators manage the references. A smart pointer can be passed by reference to a function, which avoids the need to copy-construct a new smart pointer (which would increase the reference count on entry into the function ...

  7. Weak reference - Wikipedia

    en.wikipedia.org/wiki/Weak_reference

    The Boost C++ library provides strong and weak references. It is a mistake to use regular C++ pointers as the weak counterparts of smart pointers because such usage removes the ability to detect when the strong reference count has gone to 0 and the object has been deleted. Worse yet, it does not allow for detection of whether another strong ...

  8. Value type and reference type - Wikipedia

    en.wikipedia.org/wiki/Value_type_and_reference_type

    Many languages have explicit pointers or references. Reference types differ from these in that the entities they refer to are always accessed via references; for example, whereas in C++ it's possible to have either a std:: string and a std:: string *, where the former is a mutable string and the latter is an explicit pointer to a mutable string (unless it's a null pointer), in Java it is only ...

  9. C++/CLI - Wikipedia

    en.wikipedia.org/wiki/C++/CLI

    A tracking reference in C++/CLI is a handle of a passed-by-reference variable. It is similar in concept to using *& (reference to a pointer) in standard C++, and (in function declarations) corresponds to the ref keyword applied to types in C#, or ByRef in Visual Basic .NET. C++/CLI uses a ^% syntax to indicate a tracking reference to a handle.
