Port Requires (Uses) Interface
Ports represent interaction points through which a Classifier communicates with its environment.
The Interfaces associated with a Port specify the nature of the interactions that can occur over it. The required Interfaces of a Port characterize the requests that can be made from the EncapsulatedClassifier to its environment through this Port.
The Port Requires (Uses) Interface is drawn from a Port to an Interface. In the example below, the relationship is drawn from the Port on Engine, to the Interface definition, Transmission.
