[Acceleo 3] GetKeywords & GetEannotation [message #543774]

hi!
I have some troubles with the getkeywords & GetEannotation methods.

I want to filter my "objects" in my model. I want to get only the objects with a specific keyword ("test") specified in my model .

In a M2T template, i get the model, and after i get all the "ownedelements" of the model.
For each ownedelement i want to know if it have the specific keyword.
When i do my if/else in my template, it doesn't work.
When i just want to print the result of my condition it's print "true" ...

I really don't understand....

the code :
m is the model

[for (el : Element | m.ownedElement) ]

[if el.getEAnnotation('http://www.eclipse.org/uml2/2.0.0/UML').eGet('details').eGet('key').equalsIgnoreCase('test') ]
Condition Eannotation Good
[/if]

[if el.getKeywords().equalsIgnoreCase('test') ]
Condition KeyWord Good
[/if]
Type  : [el.getEAnnotation('http://www.eclipse.org/uml2/2.0.0/UML').eGet('details').eGet('key').toString()/] == test
Eannotation => True/False [el.getEAnnotation('http://www.eclipse.org/uml2/2.0.0/UML').eGet('details').eGet('key').equalsIgnoreCase('test')/] 
Keyword => True/False [el.getKeywords().equalsIgnoreCase('test')/]
[/for]

The result :

//This one have not the "specific" keyword

Type  : org.eclipse.emf.ecore.impl.DynamicEObjectImpl@ebb12c (eClass: org.eclipse.emf.ecore.impl.EClassImpl@1bcd5b7 (name: Invalid_Class) (instanceClassName: null) (abstract: false, interface: false)) == test
Eannotation => True/False org.eclipse.emf.ecore.impl.DynamicEObjectImpl@ebb12c (eClass: org.eclipse.emf.ecore.impl.EClassImpl@1bcd5b7 (name: Invalid_Class) (instanceClassName: null) (abstract: false, interface: false)) 
Keyword => True/False 
#####################################


//this one HAVE the specific keyword

Type  : test == test
Eannotation => True/False true 
Keyword => True/False true
#####################################

Thank for help

Benoît

Hi Benoit,

"Invalid_Class" in the result means that something during the evaluation
failed (oclIsInvalid() would return true).

e1.getEAnnotation('http://www.eclipse.org/uml2/2.0.0/UML').eGet('details').eGet('key').toString()

All three of "getEAnnotation" and the 2 "eGet" can return null,
subsequent calls resulting in invalid results (the OCL variant of an
NPE). I would have done something like this :

[if (let keyword : String =
el.getEAnnotation('http://www.eclipse.org/uml2/2.0.0/UML').eGet('details').eGet('key')
in not keyword.oclIsInvalid() and keyword.equalsIgnoreCase('test'))]

Let me know if this does the trick.

We are not on the "same way" i think... Razz

The first result is "good" in my case! Because the current object haven't the specific keyword.
"I don't care" it's make errror or not... I just want to know if it have the "specific" keyword ...

The troubles is in the second result...
In this case, the result is strange because :
- When i compare the strings that's return true ( They are the same)

Keyword => True/False [el.getKeywords().equalsIgnoreCase('test')/]

Make : 

Keyword => True/False true

(this result is good, my current object have the specific keyword)

- But when I put the SAME code in the if statement

[if el.getKeywords().equalsIgnoreCase('test') ]
Condition KeyWord Good
[/if]

Its must be print
"Condition KeyWord Good" (strings must always equals?!!)
But nothing is printed!

Why?
Do you have an issue?

I hope to be more "clearer"

Thank you for your help!

Benoit,

I can't really see why the if doesn't work in your case... Might be a
parsing issue : does it still fail if you put the condition in parentheses?

[if (el.getKeywords().equalsIgnoreCase('test')) ]

No, it's always not running......
Is it a Bug?

I am for your information, on the new 3.0 Release

Ha ... no it is not.

Take extra care as to what you really have in terms of types...

el.getEAnnotation('http://www.eclipse.org/uml2/2.0.0/UML').eGet('details').eGet('key')

If I am not mistaken, "eGet('details')" returns a list, thus
"eGet('key')" is the same as "->collect(eGet('key'))", and it returns a
list of Strings. Printing a list such as "[Sequence{true}/]" will
generate "true"... yet "Sequence{true} = true" is false (as is
"Sequence{'test'} = 'test'")!

You have to either take only the first returned String or change your
condition.

-----
[if el.getKeywords().equalsIgnoreCase('test')->includes(true) ]
-----
[if el.getKeywords()->first().equalsIgnoreCase('test') ]
-----

Should both do the trick in your case.

yes in know the probleme of the list.. But i havn't access to the First() method :'( ! I don't know why ...

That's Good with "->includes(true) "

Thanks a lot for the solution and for the explains too ! !
