  2. Chain-of-responsibility pattern - Wikipedia

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

    In object-oriented design, the chain-of-responsibility pattern is a behavioral design pattern consisting of a source of command objects and a series of processing objects. [1] Each processing object contains logic that defines the types of command objects that it can handle; the rest are passed to the next processing object in the chain.

  3. Fluent interface - Wikipedia

    en.wikipedia.org/wiki/Fluent_interface

    A fluent interface is normally implemented by using method chaining to implement method cascading (in languages that do not natively support cascading), concretely by having each method return the object to which it is attached [citation needed], often referred to as this or self.

  4. 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).

  5. 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.

  6. Template method pattern - Wikipedia

    en.wikipedia.org/wiki/Template_method_pattern

    In object-oriented programming, the template method is one of the behavioral design patterns identified by Gamma et al. [1] in the book Design Patterns. The template method is a method in a superclass, usually an abstract superclass, and defines the skeleton of an operation in terms of a number of high-level steps.

  7. Adapter pattern - Wikipedia

    en.wikipedia.org/wiki/Adapter_pattern

    In software engineering, the adapter pattern is a software design pattern (also known as wrapper, an alternative naming shared with the decorator pattern) that allows the interface of an existing class to be used as another interface. [1]

  8. Factory method pattern - Wikipedia

    en.wikipedia.org/wiki/Factory_method_pattern

    Based on the type passed to the PersonFactory object, the original concrete object is returned as the interface IPerson. A factory method is just an addition to the PersonFactory class. It creates the object of the class through interfaces but also allows the subclass to decide which class is instantiated.

  9. Mediator pattern - Wikipedia

    en.wikipedia.org/wiki/Mediator_pattern

    The mediator [1] design pattern is one of the twenty-three well-known 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.
