- Object_composition abstract "In computer science, object composition (not to be confused with function composition) is a way to combine simple objects or data types into more complex ones. Compositions are a critical building block of many basic data structures, including the tagged union, the linked list, and the binary tree, as well as the object used in object-oriented programming.A real-world example of composition may be seen in the relation of an automobile to its parts, specifically: the automobile 'has or is composed from' objects including steering wheel, seat, gearbox and engine.When, in a language, objects are typed, types can often be divided into composite and noncomposite types, and composition can be regarded as a relationship between types: an object of a composite type (e.g. car) "has an" object of a simpler type (e.g. wheel).Composition must be distinguished from subtyping, which is the process of adding detail to a general data type to create a more specific data type. For instance, cars may be a specific type of vehicle: car is a vehicle. Subtyping doesn't describe a relationship between different objects, but instead, says that objects of a type are simultaneously objects of another type.In programming languages, composite objects are usually expressed by means of references from one object to another; depending on the language, such references may be known as fields, members, properties or attributes, and the resulting composition as a structure, storage record, tuple, user-defined type (UDT), or composite type. Fields are given a unique name so that each one can be distinguished from the others. However, having such references doesn't necessarily mean that an object is a composite. It is only called composite if the objects it refers to are really its parts, i.e. have no independent existence. For details, see the aggregation section below.".
