ElementConstraints:
Signature: signature_refer_to() : Boolean;
Description: The signature must either refer an Operation (in which case messageSort
is either synchCall or asynchCall) or a Signal (in which case messageSort
is asynchSignal). The name of the NamedElement referenced by signature
must be the same as that of the Message.
Expression: true
Signature: signature_is_signal() : Boolean;
Description: In the case when the Message signature is a Signal, the arguments of the
Message must correspond to the attributes of the Signal. A Message Argument
corresponds to a Signal Attribute if the Arguement is of the same Class
or a specialization of that of the Attribute.
Expression: true
Signature: signature_is_operation() : Boolean;
Description: In the case when the Message signature is an Operation, the arguments of
the Message must correspond to the parameters of the Operation. A Parameter
corresponds to an Argument if the Argument is of the same Class or a specialization
of that of the Parameter.
Expression: true
Signature: sending_receiving_message_event() : Boolean;
Description: If the sendEvent and the receiveEvent of the same Message are on the same
Lifeline, the sendEvent must be ordered before the receiveEvent.
Expression: true
Signature: occurrence_specifications() : Boolean;
Description: If the MessageEnds are both OccurrenceSpecifications then the connector
must go between the Parts represented by the Lifelines of the two MessageEnds.
Expression: true
Signature: cannot_cross_boundaries() : Boolean;
Description: Messages cannot cross bounderies of CombinedFragments or their operands.
Expression: true
Signature: arguments() : Boolean;
Description: Arguments of a Message must only be: i) attributes of the sending lifeline
ii) constants iii) symbolic values (which are wildcard values representing
any legal value) iv) explicit parameters of the enclosing Interaction v)
attributes of the class owning the Interaction
Expression: true
Operations:
No additional operations.
