Classifier (UML)

A classifier is a category of Unified Modeling Language (UML) elements that have some common features, such as attributes or methods.[1]

Overview

A classifier is an abstract metaclass classification concept that serves as a mechanism to show interfaces, classes, datatypes and components.

A classifier describes a set of instances that have common behavioral and structural features (operations and attributes, respectively).

A classifier is a namespace whose members can specify a generalization hierarchy by referencing its general classifiers.

A classifier is a type and can own generalizations, thereby making it possible to define generalization relationships to other classifiers.

A classifier is a redefinable element, as it is possible to redefine nested classifiers.

All objects that can have instances are classifiers.
