Possibility to have several levels in an XMI File? [message #547629]

Mon, 19 July 2010 04:12

Eclipse User

Hello is it possible to have something like

sequenceFlow sourceRef="Sum &lt; 10000 CHF" targetRef="Give positive feedback">
				<conditionExpression>Request accepted</conditionExpression>
			</sequenceFlow>

Until now, I was just able to handle something like:

<sequenceFlow sourceRef="Sum &lt; 10000 CHF" targetRef="Give positive feedback"/>

I need this two levels, please could you help me? Thanks and cheers

Roger

Indicate in your metamodel that for a SequenceFlow, conditions are
"contained". So EMF will store conditions into corresponding SeqFlow...

Thanks for your answer!

Can you explain that a bit more detailed, I do not understand what you exactly mean?

Thanks and cheers

The structure of your model s managed by EMF which itself relies on the
metamodel syntax.

If you want a type (like SequenceFlow) to hold an underlying type (like
Expression) through a reference (as your conditionExpression), you must
declare it in the metamodel (that is set ON the containment value of the
reference):

Class SequenceFlow
reference conditionExpression
containment = true
eType = Expression

Hello Vincent

I checkde the settings and they are really like you described. How can I then call this in a transformation rule, do I need a "lazy rule"?
Because I need 4 classes (ControlFlow --> Sequence Flow and Event --> ConditionExpression) and in a rule I can just have two classes, right?

Thanks and cheers

In a rule you can have as many output elements as you want (1 or more though)

Ok, how can I do that then? I have the following rule:

rule Flow {
from
	e : EPK!ControlFlow (not e.isConditionExpression())

to 
	b : BPMN!SequenceFlow or Expression
	 (
	 	id <- e.id,
	 	name <- e.name,
	 	sourceRef <- e.source,
	 	targetRef <- e.target
 	)
 }

Thanks and cheers Roger

Hello is it possible to have something like

sequenceFlow sourceRef="Sum &lt; 10000 CHF" targetRef="Give positive feedback">
				<conditionExpression>Request accepted</conditionExpression>
			</sequenceFlow>

Until now, I was just able to handle something like:

<sequenceFlow sourceRef="Sum &lt; 10000 CHF" targetRef="Give positive feedback"/>

I need this two levels, please could you help me?

I set now the correct settings on the metamodel, but now how can I call the second class <conditionExpression>?

Cheers Roger

to
b : BPMN!SequenceFlow(
bindings...
),
c : BPMN!Expression (
bindings...
)

Of course you can use b in the bindings of c or c in the bindings of b to make the link between the two if needed

Thanks this worked pretty fine. Smile

My next issue is to call a helper within the bindings and then to give the name back to the rule. The problem is I don't know how to call a helper inside an rule and to overgive the helper some values (variables) and to get also some back...Is this possible?

My rule looks:
-- Rule 13 / 11a with conditionalExpression
rule ConditionExpression {
from
e : EPK!ControlFlow (e.isConditionExpression())
to
b : BPMN!SequenceFlow
(
name <- e.name
),
con : BPMN!ConditionExpression(
name <- thisModule.getConditionName( overgive id, take back name)
)
}

My helper looks:

--Make two level - Rule 13 with conditionalExpression
helper context EPK!ControlFlow def: getConditionName(take id, give back name ) : Sequence(String) =
EPK!Event.allInstances()-> select(e | e.target=self.id)->collect(e | e.name);

Thank you very much that you looking at it....I am really close to my target, if this works. Smile

Cheers Roger

Hello Vincent

What do you mean with?

conditionExpression <- c

What is this c for?
I want to call a helper inside a rule and overgive some values and get back some values as you can see it above (fat) signed.

Thanks and cheers Roger

Sorry! It is :

conditionExpression <- con

(you have to include the condition into the sequece flow)
