Hi all,
I would like to know if there are scheduling informations about messages
in an interaction (sequence diagram)
I try to find this in the UML model. But I don't think we can know the
previous/next message of another through the model with the
MessageOccurrenceSpecification or the BehaviorExecutionSpecification.
Does the model really contain messages scheduling informations ?
Regards,

Hi James,
I saw an Interaction contains an ordered list of InteractionFragment in
the fragment property. This enables to know the order of messages.
When you say:
The MessageOccurrenceSpecification are the "ends" of the message.
Ok but there is a MessageOccurrenceSpecification for the beginning too
(the send event).
I need to do M2M transformation from a sequence diagram (input) to an
activity diagram (output). So this ordered list could help me to do this.
Thank you.

Hi Emilien,
An Interaction contains an ordered list of InteractionFragment.
OccurrenceSpecifications (ie. MessageOccurrenceSpecifictions ) are
InteractionFragments. The MessageOccurrenceSpecification are the "ends" of
the message. You can therefore make some general conclusions about which
message happens before which other message.
There are certain message orderings you will not be able to figure out. For
example if a message is connected to a gate at both ends of the message,
then you will have no idea what order that message comes in. ( Gate is a
MessageEnd but not an OccurrenceSpecification ).
Hope that helps.
- James.
