  2. Type introspection - Wikipedia

    en.wikipedia.org/wiki/Type_introspection

    Introspection should not be confused with reflection, which goes a step further and is the ability for a program to manipulate the metadata, properties, and functions of an object at runtime. Some programming languages also possess that capability (e.g., Java, Python, Julia, and Go).

  3. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    Many widely used languages, such as C++, Java, and Python, provide object-oriented features. Although in the past object-oriented programming was widely accepted, [ 53 ] more recently essays criticizing object-oriented programming and recommending the avoidance of these features (generally in favor of functional programming ) have been very ...

  4. Foreach loop - Wikipedia

    en.wikipedia.org/wiki/Foreach_loop

    The cursor's feature item provides access to each structure element. Descendants of class ITERATION_CURSOR can be created to handle specialized iteration algorithms. The types of objects that can be iterated across (my_list in the example) are based on classes that inherit from the library class ITERABLE.

  5. Object model - Wikipedia

    en.wikipedia.org/wiki/Object_model

    In computing, object model has two related but distinct meanings: The properties of objects in general in a specific computer programming language, technology, notation or methodology that uses them. Examples are the object models of Java, the Component Object Model (COM), or Object-Modeling Technique (OMT).

  6. Python syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/Python_syntax_and_semantics

    A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java. However, there are some ...

  7. List of object-oriented programming languages - Wikipedia

    en.wikipedia.org/wiki/List_of_object-oriented...

    This is a list of notable programming languages with features designed for object-oriented programming (OOP). The listed languages are designed with varying degrees of OOP support. Some are highly focused in OOP while others support multiple paradigms including OOP.

  8. Factory method pattern - Wikipedia

    en.wikipedia.org/wiki/Factory_method_pattern

    According to Design Patterns: Elements of Reusable Object-Oriented Software: "Define an interface for creating an object, but let subclasses decide which class to instantiate. Factory method lets a class defer instantiation to subclasses." [2] Creating an object often requires complex processes not appropriate to include within a composing object.

  9. Object copying - Wikipedia

    en.wikipedia.org/wiki/Object_copying

    These features have the potential to create many new objects, because they duplicate all the objects in an entire object structure. Because new duplicate objects are created instead of simply copying references to existing objects, deep operations will become a source of performance issues more readily than shallow operations.
