(object-oriented programming) A constructor that takes an existing instance as a parameter and copies its values.

John von Neumann's universal constructor is a self-replicating machine in a cellular automaton environment.

a proposal for a new mode of explanation in fundamental physics in the language of ergodic theory, developed by physicists David Deutsch and Chiara Marletto, at the University of Oxford, since 2012.

In computer programming languages, the term default constructor can refer to a constructor that is automatically generated by the compiler in the absence of any programmer-defined constructors (e.g. in Java), and is usually a nullary constructor.

In the area of mathematical logic and computer science known as type theory, a type constructor is a feature of a typed formal language that builds new types from old ones.

In computer programming, a nullary constructor is a constructor that takes no arguments.
