UML PROFILE FOR SAVECCM - Research

SaveUML profile
connections. Although UML ports are intended to be used through UML interfaces
attached to them, they can nevertheless be used without interfaces, i.e. they can
be connected to each other directly which is equivalent to the SaveCCM model.
Considering different types of ports with respect to port direction and type, it
was reasonable to design a separate port stereotype for each direction and type
combination which resulted in altogether six port stereotypes. The rationale for
using UML port as the base classifier is the same for all port stereotypes.
Stereotypes differ in their connection possibilities which are specified through
constraints.
This stereotype is used for modelling combined input port.
Base classifier: Port
Tagged values:
• Type : String. A type of data.
• Value : String. Initial value of data (optionally).
• External : String. A label mapping the port to external entity, in case a port is an
external port.
• SetPort : Boolean. Indicates if a port is used in a switch condition. If it is set to
‘true’, then the port is used in a switch condition (a consequence is that a
component that owns this port must be a switch component – component with
SaveSwitch stereotype applied). Default value is set to ‘false’.
Constraints:
[1] NumberOfStereotypes: see the SaveAssembly constraint [6].
[2] OwnerComponentStereotype: This constraint ensures that an owner component
(the component that owns the port) has an appropriate stereotype applied. By
appropriate stereotype it is considered to be one of the stereotypes defined by
SaveUML profile that are used to model SaveCCM main architectural elements.
[3] PortConnections: As SaveCCM offers only two types of connections (see section
5.3.5), the port can be connected to other port with only two kinds of connectors.
Those two kinds are the ones used by SaveUML profile for modelling SaveCCM
connections; Usage and Dependency. No other connections are allowed.
[4] PortConnectionStereotype: To ensure that connections used for connecting the
port to other ports have the appropriate stereotype applied, this constraint checks if
the connections have one of two allowed stereotypes; SaveConnection or
SaveDelegation.
[5] PortsExternal: External ports are not allowed internally within a composite
component or assembly. If an "External" tagged value is not empty, then this
constraint checks if the owner component is composite or assembly component
(component with SaveComposite or SaveAssembly stereotype applied).
