Show Realized Interfaces of Class
If you are modeling interfaces that are directly realized by a Class, you can render each of those interfaces as a 'lollipop' style interface node, which protrudes from the left-hand side of the Class. Connectors can be directly attached to the node, indicating use of the interface part of the Class or Component, as shown:
In this example, Class2 realizes Interface1 and Interface2, as represented by the interface nodes protruding from the Class. Class1 is dependent on these two interfaces, as shown by the Dependency connectors linking to the nodes.
To show nodes for the interfaces a Class realizes, right-click on the Class and select Features & Properties | Show Realized Interfaces. This setting only applies to the selected Class, and can be changed at any time.
