  2. Mutator method - Wikipedia

    en.wikipedia.org/wiki/Mutator_method

    Modern programming languages often offer the ability to generate the boilerplate for mutators and accessors in a single line—as for example C#'s public string Name { get; set; } and Ruby's attr_accessor :name. In these cases, no code blocks are created for validation, preprocessing or synthesis.

  3. C Sharp syntax - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_syntax

    Identifier names may be prefixed by an at sign (@), but this is insignificant; @name is the same identifier as name. Microsoft has published naming conventions for identifiers in C#, which recommends the use of PascalCase for the names of types and most type members, and camelCase for variables and for private or internal fields.

  4. Null coalescing operator - Wikipedia

    en.wikipedia.org/wiki/Null_coalescing_operator

    The null coalescing operator is a binary operator that is part of the syntax for a basic conditional expression in several programming languages, such as (in alphabetical order): C# [1] since version 2.0, [2] Dart [3] since version 1.12.0, [4] PHP since version 7.0.0, [5] Perl since version 5.10 as logical defined-or, [6] PowerShell since 7.0.0, [7] and Swift [8] as nil-coalescing operator.

  5. Naming convention (programming) - Wikipedia

    en.wikipedia.org/wiki/Naming_convention...

    In Python, if a name is intended to be "private", it is prefixed by one or two underscores. Private variables are enforced in Python only by convention. Names can also be suffixed with an underscore to prevent conflict with Python keywords. Prefixing with double underscores changes behaviour in classes with regard to name mangling.

  6. Access modifiers - Wikipedia

    en.wikipedia.org/wiki/Access_modifiers

    The meaning of these modifiers may differ from one language to another. A comparison of the keywords, ordered from the most restrictive to the most open, and their meaning in these three languages follows. Their visibility ranges from the same class to the package where the class is defined to a general access permission.

  7. Property (programming) - Wikipedia

    en.wikipedia.org/wiki/Property_(programming)

    A property, in some object-oriented programming languages, is a special sort of class member, intermediate in functionality between a field (or data member) and a method.The syntax for reading and writing of properties is like for fields, but property reads and writes are (usually) translated to 'getter' and 'setter' method calls.

  8. Lazy initialization - Wikipedia

    en.wikipedia.org/wiki/Lazy_initialization

    In computer programming, lazy initialization is the tactic of delaying the creation of an object, the calculation of a value, or some other expensive process until the first time it is needed.

  9. List comprehension - Wikipedia

    en.wikipedia.org/wiki/List_comprehension

    Here, the list [0..] represents , x^2>3 represents the predicate, and 2*x represents the output expression.. List comprehensions give results in a defined order (unlike the members of sets); and list comprehensions may generate the members of a list in order, rather than produce the entirety of the list thus allowing, for example, the previous Haskell definition of the members of an infinite list.
