  2. Method chaining - Wikipedia

    en.wikipedia.org/wiki/Method_chaining

    Method chaining is a common syntax for invoking multiple method calls in object-oriented programming languages. Each method returns an object, allowing the calls to be chained together in a single statement without requiring variables to store the intermediate results.

  3. Method cascading - Wikipedia

    en.wikipedia.org/wiki/Method_cascading

    Cascading can be implemented in terms of chaining by having the methods return the target object (receiver, this, self).However, this requires that the method be implemented this way already – or the original object be wrapped in another object that does this – and that the method not return some other, potentially useful value (or nothing if that would be more appropriate, as in setters).

  4. Exception chaining - Wikipedia

    en.wikipedia.org/wiki/Exception_chaining

    Exception chaining, or exception wrapping, is an object-oriented programming technique of handling exceptions by re-throwing a caught exception after wrapping it inside a new exception. The original exception is saved as a property (such as cause) of the new exception. The idea is that a method should throw exceptions defined at the same ...

  5. Fluent interface - Wikipedia

    en.wikipedia.org/wiki/Fluent_interface

    A common example is the iostream library in C++, which uses the << or >> operators for the message passing, sending multiple data to the same object and allowing "manipulators" for other method calls. Other early examples include the Garnet system (from 1988 in Lisp) and the Amulet system (from 1994 in C++) which used this style for object ...

  6. Entity component system - Wikipedia

    en.wikipedia.org/wiki/Entity_component_system

    That is, any complete component object system can be expressed with the templates and empathy model within The Orlando Treaty [2] vision of object-oriented programming. Entity: An entity represents a general-purpose object. In a game engine context, for example, every coarse game object is represented as an entity.

  7. Game Oriented Assembly Lisp - Wikipedia

    en.wikipedia.org/wiki/Game_Oriented_Assembly_Lisp

    Game Oriented Object Lisp (GOOL) Game Oriented Assembly Lisp ( GOAL , also known as Game Object Assembly Lisp ) is a programming language , a dialect of the language Lisp , made for video games developed by Andy Gavin and the Jak and Daxter team at the company Naughty Dog .

  8. Visitor pattern - Wikipedia

    en.wikipedia.org/wiki/Visitor_pattern

    It should be possible to define a new operation for (some) classes of an object structure without changing the classes. When new operations are needed frequently and the object structure consists of many unrelated classes, it's inflexible to add new subclasses each time a new operation is required because "[..] distributing all these operations across the various node classes leads to a system ...

  9. Safe navigation operator - Wikipedia

    en.wikipedia.org/wiki/Safe_navigation_operator

    In object-oriented programming, the safe navigation operator (also known as optional chaining operator, safe call operator, null-conditional operator, null-propagation operator) is a binary operator that returns null if its first argument is null; otherwise it performs a dereferencing operation as specified by the second argument (typically an ...
