  2. Enumerated type - Wikipedia

    en.wikipedia.org/wiki/Enumerated_type

    Defining getters allows then access to those self-defined members. The internal integer can be obtained from an enum value using the ordinal() method, and the list of enum values of an enumeration type can be obtained in order using the values() method. It is generally discouraged for programmers to convert enums to integers and vice versa. [9]

  3. Indexer (programming) - Wikipedia

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

    In this example, the indexer is used to get the value at the nth position, and then to get the position in the list referenced by its value. The output of the code is: John is the member number 0 of the doeFamily Jane is the member number 1 of the doeFamily

    For a sorted dictionary, the programmer could choose to use a SortedDictionary<TKey, TValue> or use the .Sort LINQ extension method when enumerating. The following demonstrates enumeration using a foreach loop:

  7. Fold (higher-order function) - Wikipedia

    en.wikipedia.org/wiki/Fold_(higher-order_function)

    Folds can be regarded as consistently replacing the structural components of a data structure with functions and values. Lists, for example, are built up in many functional languages from two primitives: any list is either an empty list, commonly called nil ([]), or is constructed by prefixing an element in front of another list, creating what is called a cons node ( Cons(X1,Cons(X2,Cons ...

  8. Enumeration - Wikipedia

    en.wikipedia.org/wiki/Enumeration

    In set theory, there is a more general notion of an enumeration than the characterization requiring the domain of the listing function to be an initial segment of the Natural numbers where the domain of the enumerating function can assume any ordinal. Under this definition, an enumeration of a set S is any surjection from an ordinal α onto S ...

  9. Data type - Wikipedia

    en.wikipedia.org/wiki/Data_type

    The standard type hierarchy of Python 3. In computer science and computer programming, a data type (or simply type) is a collection or grouping of data values, usually specified by a set of possible values, a set of allowed operations on these values, and/or a representation of these values as machine types.
