In software engineering, a software design pattern or design pattern is a general, reusable solution to a commonly occurring problem in many contexts in software design. [1] A design pattern is not a rigid structure that can be transplanted directly into source code. Rather, it is a description or a template for solving a particular type of ...
Modern C++ Design: Generic Programming and Design Patterns Applied is a book written by Andrei Alexandrescu, published in 2001 by Addison-Wesley. It has been regarded as "one of the most important C++ books" by Scott Meyers. [1] The book makes use of and explores a C++ programming technique called template metaprogramming. While Alexandrescu ...
Apache C++ Standard Library (The starting point for this library was the 2005 version of the Rogue Wave standard library [15]) Libstdc++ uses code derived from SGI STL for the algorithms and containers defined in C++03. Dinkum STL library by P.J. Plauger; The Microsoft STL which ships with Visual C++ is a licensed derivative of Dinkum's STL.
In software engineering, the delegation pattern is an object-oriented design pattern that allows object composition to achieve the same code reuse as inheritance. In delegation, an object handles a request by delegating to a second object (the delegate). The delegate is a helper object, but with the original context.
Design pattern, overview of design patterns in general; Abstract factory pattern, a pattern often implemented using factory methods; Builder pattern, another creational pattern; Template method pattern, which may call factory methods; Joshua Bloch's idea of a static factory method for which Bloch claims there is no direct equivalent in Design ...
Code within a Role method may invoke a method on self and thereby invoke a method of the data part of the current object. One curious aspect of DCI is that these bindings are guaranteed to be in place only at run time (using a variety of approaches and conventions; C++ templates can be used to guarantee that the bindings will succeed [7]).
Object-oriented design uses the access specifiers in conjunction with careful design of public method implementations to enforce class invariants—constraints on the state of the objects. A common usage of access specifiers is to separate the internal data of a class from its interface: the internal structure is made private, while public ...
The client code deals only with the abstract type. Objects of a concrete type are indeed created by the factory, but the client code accesses such objects only through their abstract interfaces. [6] Adding new concrete types is performed by modifying the client code to use a different factory, a modification that is typically one line in one file.
