Class UML 2.3::Connector

Description:

A delegation connector is a connector that links the external contract of a component (as specified by its ports) to the realization of that behavior. It represents the forwarding of events (operation requests and events): a signal that arrives at a port that has a delegation connector to one or more parts or ports on parts will be passed on to those targets for handling. An assembly connector is a connector between two or more parts or ports on parts that defines that one or more parts provide the services that other parts use.

Class Precedence List: Connector, Feature, RedefinableElement, NamedElement, Element

Properties:

contract : Behavior (0 *); -- source Connector
end : ConnectorEnd (2 *); -- source Connector
kind : ConnectorKind (1 1); -- source Connector
redefinedConnector : Connector (0 *); -- source Connector

A connector may be redefined when its containing classifier is specialized. The redefining connector may have a type that specializes the type of the redefined connector. The types of the connector ends of the redefining connector may specialize the types of the connector ends of the redefined connector. The properties of the connector ends of the redefining connector may be replaced.

Constraints:

Signature: types() : Boolean;
Description: The types of the connectable elements that the ends of a connector are attached to must conform to the types of the association ends of the association that types the connector, if any.
Expression: true

Signature: roles() : Boolean;
Description: The ConnectableElements attached as roles to each ConnectorEnd owned by a Connector must be roles of the Classifier that owned the Connector, or they must be ports of such roles.
Expression: true

Signature: compatible() : Boolean;
Description: The connectable elements attached to the ends of a connector must be compatible.
Expression: true

Signature: between_interfaces_ports() : Boolean;
Description: Each feature of each of the required interfaces of each Port or Part at the end of a connector must have at least one compatible feature among the features of the provided interfaces of Ports or Parts at the other ends, where the required set of (interface) features of a delegating port from the context of the delegating connector is the set of features that exist in the port's provided interfaces, and the provided set of (interface) features of a delegating port from the context of the delegating connector is the set of features that exist in the port's required interfaces.
Expression: true

Operations:

Signature: kind.1() : ConnectorKind;
Description:
Expression: result = if end->exists( role.oclIsKindOf(Port) and partWithPort->isEmpty() and not role.oclAsType(Port).isBehavior) then ConnectorKind::delegation else ConnectorKind::assembly endif
