A class diagram exemplifying the singleton pattern.. In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance.
Benjamin "Pap" Singleton (1809 – February 17, 1900) was an American activist and businessman best known for his role in establishing African American settlements in Kansas. A former slave from Tennessee who escaped to freedom in Ontario, Canada in 1846, he soon returned to the United States, settling for a period in Detroit, Michigan .
A set such as {{,,}} is a singleton as it contains a single element (which itself is a set, but not a singleton). A set is a singleton if and only if its cardinality is 1. In von Neumann's set-theoretic construction of the natural numbers, the number 1 is defined as the singleton {}.
Singleton pattern, a design pattern that allows only one instance of a class to exist; Singleton bound, used in coding theory; Singleton variable, a variable that is referenced only once; Singleton, a character encoded with one unit in variable-width encoding schemes for computer character sets
Whereas the singleton allows only one instance of a class to be created, the multiton pattern allows for the controlled creation of multiple instances, which it manages through the use of a map. Rather than having a single instance per application (e.g. the java.lang.Runtime object in the Java programming language ) the multiton pattern instead ...
Henry Earl Singleton (November 27, 1916 – August 31, 1999) was an American electrical engineer, business executive, and rancher/land owner. Singleton made significant contributions to aircraft inertial guidance and was elected to the National Academy of Engineering .
In coding theory, the Singleton bound, named after Richard Collom Singleton, is a relatively crude upper bound on the size of an arbitrary block code with block length , size and minimum distance . It is also known as the Joshibound [ 1 ] proved by Joshi (1958) and even earlier by Komamiya (1953) .
[6] [7] The narrative describes the life of the Englishman, Singleton, stolen from a well-to-do family as a child and raised by Gypsies, eventually making his way to sea.
