![]() The contents of slots, if any, are included below the names, in a separate attribute compartment.Ī link is shown as a solid line, and represents an instance of an association. The name on an instance specification optionally shows an instance name, a ':' separator, and optionally one or more classifier names separated by commas. Each slot corresponds to a single attribute or feature, and may include a value for that entity. an abstract or concrete class) and instance name, as well as attributes and other structural features using slots. This can show an object's classifier (e.g. Object diagram topics Instance specifications Įach object and link on an object diagram is represented by an InstanceSpecification. Only aspects of current interest in a model are typically shown on an object diagram. They are often used to provide examples or act as test cases for class diagrams. Object diagrams are more concrete than class diagrams. While class diagrams show classes, object diagrams display instances of classes ( objects). You can draw Class Diagram quickly through the intuitive drawing editor. Both diagrams are meant to visualize static structure of a system. The drawing tool, Visual Paradigm Online (VP Online), supports Class Diagram, UML, ERD and Organization Chart. Object diagrams and class diagrams are closely related and use almost identical notation. The latest UML 2.5 specification does not explicitly define object diagrams, but provides a notation for instances of classifiers. ![]() The use of object diagrams is fairly limited, namely to show examples of data structure." A static object diagram is an instance of a class diagram it shows a snapshot of the detailed state of a system at a point in time. ![]() "An object diagram is a graph of instances, including objects and data values. Early UML specifications described object diagrams as such: A correlated set of object diagrams provides insight into how an arbitrary view of a system is expected to evolve over time. In the Unified Modeling Language (UML), an object diagram focuses on some particular set of objects and attributes, and the links between these instances.
