Service Interface Diagram ¶

The ServiceInterface diagram is dedicated to model ServiceInterfaces, Providers, Consumers and their relationships. The Capabilities can be dragged and dropped to show “expose” relationships between Service Interfaces and Capabilities.

4.2.1 Palette¶

Table 6 Service Interface Diagram Palette

Command	Description
ServiceInterface	Creates a Class with SoaML.ServiceInterface stereotype Stereotype representation: “text” Restrictions: ServiceInterfaces inside of ServiceInterface should not be created.
Provider	Creates a Interface with SoaML.Provider stereotype Stereotype representation: “text” SmartAction: 1. If clicked inside of exiting ServiceInterface, a new part is created typed by newly created additional “Provider”
Consumer	Creates a Interface with SoaML.Consumer stereotype Stereotype representation: “text” SmartAction: If clicked inside of exiting ServiceInterface, a new part is created typed by newly created additional “Consumer”
Operation	Creates an Operation inside a Service Interface, Provider or COnsumer
Smart “Realize” link	SmartAction: If target element is a Class, creates “Generalization” link If target element is an Interface, creates “Realization” link
"Use" link	Creates Dependency with “use” stereotype Stereotype representation: “text”
"Connector" link	Creates Connector between 2 internal parts, e.g. two roles representing Provider or Consumer interfaces. Stereotype representation: “text”
“Expose” link	Creates an dependency with SoaML.Expose stereotype between ServiceInterface and a Capability Stereotype representation: “text” Restriction: Link between a ServiceInterface and a Capability only
Traceability link	Creates a traceability between two model elements
Note	Creates a Note for a model element

Advanced Features¶

The advanced features are available when right-clicking on a relevant element in the model explorer.

“derive ServiceInterface” command¶

Applicable to: “Provider” interface.

Action: Creates a “ServiceInterface” class with all operations of the “realized” interface.

Smart action: This command is applicable to a multiple selection of “Provider” interfaces

Figure 11 Derive Service Interface Command

“conjugate ServiceInterface” command¶

Applicable to: “ServiceInerface” class

Action: Creates a “ServiceInterface” class, with the following properties

• name starting with “~”, e.g. for “PO Service” service interface, a “~PO Service” service interface is created
• “Realize” links of service interface, become “use” links of conjugate service interface
• “Use” links of service interface, become “realize” links of conjugate service interface
• All operations of “realized” interfaces are copied into the service interface

Smart action: This command is applicable to a multiple selection of “ServiceInerface” classes

Use Cases¶

This is the major use case extracted from the SoaML specification and implemented in the SoaML Modelio module, including conjugate Service Interface definition:
