Class UML 2.4.1::Port
Description:
A port has an associated protocol state machine.A port is a property of
a classifier that specifies a distinct interaction point between that classifier
and its environment or between the (behavior of the) classifier and its
internal parts. Ports are connected to properties of the classifier by
connectors through which requests can be made to invoke the behavioral
features of a classifier. A Port may specify the services a classifier
provides (offers) to its environment as well as the services that a classifier
expects (requires) of its environment.
