- Trait_(computer_programming) abstract "In computer programming, a trait is a concept used in object-oriented programming: a trait represents a collection of methods, that can be used to extend the functionality of a class.Essentially a trait is similar to a class made only of concrete methods that is used to extend another class with a mechanism similar to multiple inheritance, but paying attention to name conflicts, hence with some support from the language for a name-conflict resolution policy to use when merging.Traits provide a "simple conceptual model for structuring object-oriented programs" similar to mixins. Traits provide a simple way to create classes that reuse behavior from software components.Traits are somewhat between an interface and a mixin: an interface is made only of method signatures, while a trait includes also the full method definitions, on the other side mixins include method definitions, but they can also carry state through attributes while traits usually don't.An interface is used by a class by "implementing" its methods.A mixin is used by a class by mixing-into itself all the features of the mixin: i.e. the attributes and the methods.A trait is used by a class by merging the collection of extra methods provided with some mechanism to resolve name conflicts.Hence an object defined as a trait is created as the composition of methods, which can be used by other classes without requiring multiple inheritance. In case of a naming collision, when more than one trait to be used by a class has a method with the same name, the programmer must explicitly disambiguate which one of those methods will be used in the class; thus manually solving the "diamond problem" of repeated inheritance. This is different from other composition methods in object-oriented programming, where conflicting names are automatically resolved by scoping rules.Whereas mixins can be composed only using the inheritance operation, traits offer a much wider selection of operations, including: symmetric sum: an operation that merges two disjoint traits to create a new trait override (or asymmetric sum): an operation that forms a new trait by adding additional methods possibly overriding some of the methods of an existing trait alias: an operation that creates a new trait by adding a new name for an existing method and exclusion: an operation that forms a new trait by removing a method from an existing trait. (Combined with the alias operation yields a shallow rename operation).A trait differs from an interface in that it provides implementations of its methods, not just type signatures.".
