2. Class (computer programming) - Wikipedia

   en.wikipedia.org/wiki/Class_(computer_programming)

   A class defines an implementation of an interface, and instantiating the class results in an object that exposes the implementation via the interface. [3] In the terms of type theory, a class is an implementation‍—‌a concrete data structure and collection of subroutines‍—‌while a type is an interface. Different (concrete) classes ...

3. Jython - Wikipedia

   en.wikipedia.org/wiki/Jython

   Jython includes almost all of the modules in the standard Python programming language distribution, lacking only some of the modules implemented originally in C. For example, a user interface in Jython could be written with Swing, AWT or SWT. Jython compiles Python source code to Java bytecode (an intermediate language) either on demand or ...

4. Factory method pattern - Wikipedia

   en.wikipedia.org/wiki/Factory_method_pattern

   Factory method pattern. In object-oriented programming, the factory method pattern is a design pattern that uses factory methods to deal with the problem of creating objects without having to specify their exact classes. Rather than by calling a constructor, this is accomplished by invoking a factory method to create an object.

5. Visitor pattern - Wikipedia

   en.wikipedia.org/wiki/Visitor_pattern

   This example declares a separate ExpressionPrintingVisitor class that takes care of the printing. If the introduction of a new concrete visitor is desired, a new class will be created to implement the Visitor interface, and new implementations for the Visit methods will be provided. The existing classes (Literal and Addition) will remain unchanged.

6. Reflective programming - Wikipedia

   en.wikipedia.org/wiki/Reflective_programming

   In object-oriented programming languages such as Java, reflection allows inspection of classes, interfaces, fields and methods at runtime without knowing the names of the interfaces, fields, methods at compile time. It also allows instantiation of new objects and invocation of methods. Reflection is often used as part of software testing, such ...

7. Closure (computer programming) - Wikipedia

   en.wikipedia.org/wiki/Closure_(computer_programming)

   In programming languages, a closure, also lexical closure or function closure, is a technique for implementing lexically scoped name binding in a language with first-class functions. Operationally, a closure is a record storing a function [a] together with an environment. [1] The environment is a mapping associating each free variable of the ...

8. Bridge pattern - Wikipedia

   en.wikipedia.org/wiki/Bridge_pattern

   Bridge pattern. The bridge pattern is a design pattern used in software engineering that is meant to "decouple an abstraction from its implementation so that the two can vary independently", introduced by the Gang of Four. [1] The bridge uses encapsulation, aggregation, and can use inheritance to separate responsibilities into different classes.

9. Python (programming language) - Wikipedia

   en.wikipedia.org/wiki/Python_(programming_language)

   Python is a multi-paradigm programming language. Object-oriented programming and structured programming are fully supported, and many of their features support functional programming and aspect-oriented programming (including metaprogramming [73] and metaobjects). [74] Many other paradigms are supported via extensions, including design by ...
