Implement interface
You can automatically implement the operations of an interface for classes, datatypes, and artifacts that can have operations.
Right-click a class, a datatype, or an artifact.
Click Implement interface. The Select object dialog opens. The Search database, Browse Explorer, and Recently used objects tabs are displayed for you to select the relevant interface.
Use the tabs to select the interface whose operations you want to implement.
Click OK.
The operations of the interface are implemented. At the same time, a relationship of the interfaceRealization type is created to connect them with the interface. If the interface is implemented in the diagram, occurrences will be available of both the interface and the relationship.
