Elements of an object diagram
An object diagram includes the following elements:
  • object: represents a class instance.
    Note: If a class diagram is opened, you have the ability create an object from a class found in this diagram (Drag and Drop from the "UML analysis" pane).
  • composite object: visually represents an object made of other objects. For example: a window that contains scrollbars, buttons, ...
  • link: presents the relationships between the different objects.
  • UML package: used to divide and organize the representation of the diagram (as the directories organizes the files). Each package can contain objects and composite objects.
See Handling an object diagram for more details.
