  2. Software design pattern - Wikipedia

    en.wikipedia.org/wiki/Software_design_pattern

    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 ...

  3. Prototype pattern - Wikipedia

    en.wikipedia.org/wiki/Prototype_pattern

    The prototype design pattern is one of the 23 Gang of Four design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse. [2]: 117 The prototype design pattern solves problems like: [3]

  4. Creational pattern - Wikipedia

    en.wikipedia.org/wiki/Creational_pattern

    In software engineering, creational design patterns are design patterns that deal with object creation mechanisms, trying to create objects in a manner suitable to the situation. The basic form of object creation could result in design problems or in added complexity to the design due to inflexibility in the creation procedures.

  5. List of software architecture styles and patterns - Wikipedia

    en.wikipedia.org/wiki/List_of_software...

    Software architecture patterns operate at a higher level of abstraction than design patterns, solving broader system-level challenges. While these patterns typically affect system-level concerns, the distinction between architectural patterns and architectural styles can sometimes be blurry.

  6. GRASP (object-oriented design) - Wikipedia

    en.wikipedia.org/wiki/GRASP_(object-oriented_design)

    The indirection pattern supports low coupling and reuses potential between two elements by assigning the responsibility of mediation between them to an intermediate object. An example of this is the introduction of a controller component for mediation between data (model) and its representation (view) in the model-view-controller pattern.

  7. Double-checked locking - Wikipedia

    en.wikipedia.org/wiki/Double-checked_locking

    In software engineering, double-checked locking (also known as "double-checked locking optimization" [1]) is a software design pattern used to reduce the overhead of acquiring a lock by testing the locking criterion (the "lock hint") before acquiring the lock. Locking occurs only if the locking criterion check indicates that locking is required.

  8. Factory (object-oriented programming) - Wikipedia

    en.wikipedia.org/wiki/Factory_(object-oriented...

    In class-based programming, a factory is an abstraction of a constructor of a class, while in prototype-based programming a factory is an abstraction of a prototype object. A constructor is concrete in that it creates objects as instances of one class, and by a specified process (class instantiation), while a factory can create objects by instantiating various classes, or by using other ...

  9. Programming paradigm - Wikipedia

    en.wikipedia.org/wiki/Programming_paradigm

    The findings allow for describing and comparing programming practices and the languages used to code programs. For perspective, other fields of research study software engineering processes and describe various methodologies to describe and compare them. A programming language can be described in terms of paradigms. Some languages support only ...
