  2. Visitor pattern - Wikipedia

    en.wikipedia.org/wiki/Visitor_pattern

    Thus, the code becomes a large outer loop traversing through the objects, with a large decision tree inside the loop querying the type of the object. Another problem with this approach is that it is very easy to miss a shape in one or more savers, or a new primitive shape is introduced, but the save routine is implemented only for one file type ...

  3. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    Objects are instances of a class. Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, [1] which can contain data and code: data in the form of fields (often known as attributes or properties), and code in the form of procedures (often known as methods).

  4. 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 ...

  5. Code folding - Wikipedia

    en.wikipedia.org/wiki/Code_folding

    Code folding. Not to be confused with Constant folding. Code or text folding, or less commonly holophrasting, [ 1 ] is a feature of some graphical user interfaces that allows the user to selectively hide ("fold") or display ("unfold") parts of a document. This allows the user to manage large amounts of text while viewing only those subsections ...

  6. Reflective programming - Wikipedia

    en.wikipedia.org/wiki/Reflective_programming

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

  7. Cython - Wikipedia

    en.wikipedia.org/wiki/Cython

    cython.org. Influenced by. C, Python. Cython (/ ˈsaɪθɒn /) is a superset of the programming language Python, which allows developers to write Python code (with optional, C-inspired syntax extensions) that yields performance comparable to that of C. [5][6] Cython is a compiled language that is typically used to generate CPython extension ...

  8. For loop - Wikipedia

    en.wikipedia.org/wiki/For_loop

    v. t. e. In computer science, a for-loop or for loop is a control flow statement for specifying iteration. Specifically, a for-loop functions by running a section of code repeatedly until a certain condition has been satisfied. For-loops have two parts: a header and a body. The header defines the iteration and the body is the code that is ...

  9. Reactive programming - Wikipedia

    en.wikipedia.org/wiki/Reactive_programming

    In computing, reactive programming is a declarative programming paradigm concerned with data streams and the propagation of change. With this paradigm, it is possible to express static (e.g., arrays) or dynamic (e.g., event emitters) data streams with ease, and also communicate that an inferred dependency within the associated execution model exists, which facilitates the automatic propagation ...
