In UML, a class diagram is one of six types of structure diagrams. Some of these modeling elements are directly available through the 'UML Standard Profile' Toolbox page in the Class or Package Diagram Toolbox others can be applied as stereotypes on the base UML modeling object.The Unified Modeling Language ( UML) is a general-purpose, developmental modeling language in the field of software engineering, designed to provide a standard approach to visualizing system design. The original motivation for creating UML was the desire to standardize different notation systems and software design methods. The UML Standard Profile is a collection of stereotyped Classes, operations and relationships provided as modeling tools in compliance with the UML 2.5 Specification (Chapter 22, Standard Profile).

The Expose Interface element is a graphical method of depicting the required or supplied interfaces of a Component, Class or Part, in a Class, Component or Composite Structure diagram.Īn Assembly connector bridges a component's required interface (Component1) with the provided interface of another component (Component2), typically in a Component diagram.Ĭonnectors illustrate communication links between Parts to fulfill the structure's purpose, typically in a Class or Composite Structure diagram.Ī Delegate connector defines the internal assembly of a component's external Ports and Interfaces, on a Class diagram or Component diagram. Ports define the interaction between a classifier and its environment.

Parts are run-time instances of Classes or Interfaces. A Class is a representation of a type of object that reflects the structure and behavior of such objects within the system.Īn Interface is a specification of behavior (or contract) that implementers agree to meet.Ī Data Type is a specific kind of classifier, similar to a Class except that a Data Type cannot own sub Data Types, and instances of a Data Type are identified only by their value.Īn Enumeration is a data type, whose instances can be any of a number of user-defined enumeration literals.Ī Primitive element identifies a predefined data type, without any relevant substructure (that is, it has no parts in the context of UML).Ī Signal is a specification of Send request instances communicated between objects, typically in a Class or Package diagram.Īn n-Ary Association element is used to model complex relationships between three or more elements, typically in a Class diagram.
