Behavior Execution Specification overlapping [message #478244]

Hello everyone!
In the OMG's UML2 specification,the BehaviorExecutionSpecifications
(BES) can be overlapped (to represent sub-executions). However, there is
no explanation of how to achiveve this. In other words, how do you
represent a sub-BES in a UML2 model?

Can anyone give me a hint?

Thanks in advance.

Regards,
Gabriel.

Hi Gabriel,

The Interaction would have an ordered list of InteractionFragment (see
Interaction:getFragments() ).
The start and end points of the BehaviorExecutionSpecification would be
OccurrenceSpecification's that would be ordered in such a way as to make the
execution appear "overlapped".

For example, the Fragments collection could have the following elements.

"start_big" - ExecutionOccurrenceSpecification
"big" - BehaviorExecutionSpecification
"start_small" - ExecutionOccurrenceSpecification
"small" - BehaviorExecutionSpecification
"finish_small" - ExecutionOccurrenceSpecification
"finish_big " - ExecutionOccurrenceSpecification

Cheers,
- James.

Hi James,

Thanks for your quick answer, but I don't understand your explanation.
Which is the "root" BES and the "affixed" BES in your example? Would you
mind giving me more details in your example?

In addition, I use the start/finish properties of the to store the end
of the first/last message connected to it. Thanks to this and to the
fact that all my MOS are ordered (via GOs), I know where a Message is
really contected to.

I hope I have explained myself and thanks again for your help.

Note:
BES : BehaviorExecutionSpecification
MOS : MessageOccurrenceSpecification
GO : GeneralOrdering

Regards,
Gabriel.

Hi Gabriel,

What you are calling "root" BES, I am calling "big". What you are calling
"affixed" I am calling "small".
The "root" BES has a start and finish that I called "start_big" and
"finish_big".
The order of fragments in the fragments collection is in the order listed
previously.

The order is the key point that indicates nesting.
