4.5.2.2 Connector
A Connector is communication relationship between two parts or two ports in a
context of a component. Connectors are used to interconnect provisions and
requirements of a component. Since provisions and requirements can be specified
using ports or can be directly attached to a component, a connectors may be
attached to either ports, interfaces or components.
UML 2.0 diferentiates two kinds of connectors:
• Assembly connector – may be defined from a required interface or a port
to the provided interface or a port. In other words, it connects two
components and their provisions and requirements. Assembly connector
defines that one component provides the services which another
component requires.
• Delegate connector – connects component and its subcomponent. It is
used to connect component’s provisions to its subcomponent’s
provisions, or component’s requirements to its subcomponent’s
requirements. It represents the forwarding of signals, a signal that arrives
at a port with a delegation connector to a subcomponent, will be passed
on to that target for handling.
