  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. 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 ...

  4. Curiously recurring template pattern - Wikipedia

    en.wikipedia.org/wiki/Curiously_recurring...

    Method chaining, also known as named parameter idiom, 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.

  5. 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).

  6. Adapter pattern - Wikipedia

    en.wikipedia.org/wiki/Adapter_pattern

    When implementing the adapter pattern, for clarity, one can apply the class name [ClassName] To [Interface] Adapter to the provider implementation; for example, DAOToProviderAdapter. It should have a constructor method with an adaptee class variable as a parameter. This parameter will be passed to an instance member of [ClassName] To [Interface ...

  7. Chain-of-responsibility pattern - Wikipedia

    en.wikipedia.org/wiki/Chain-of-responsibility...

    The Chain of Responsibility [2] design pattern is one of the twenty-three well-known GoF design patterns that describe common solutions to recurring design problems when designing flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse.

  8. Observer pattern - Wikipedia

    en.wikipedia.org/wiki/Observer_pattern

    A sample UML class and sequence diagram for the observer design pattern. [6] In this UML class diagram, the Subject class does not update the state of dependent objects directly. Instead, Subject refers to the Observer interface (update()) for updating state, which makes the Subject independent of how the state of dependent objects is updated.

  9. Command pattern - Wikipedia

    en.wikipedia.org/wiki/Command_pattern

    The receiver object owns the method that is called by the command's execute method. The receiver is typically also the target object. For example, if the receiver object is a cursor and the method is called moveUp, then one would expect that the cursor is the target of the moveUp action. On the other hand, if the code is defined by the command ...
