[Teneo] : Transient annotation not working on EClass. [message #80845] Tue, 24 April 2007 11:13 Go to next message

Hi,
im having a problem with the Transient annotation when set on an EClass. Im using an
annotations.xml file with the following entry:

<epackage namespace-uri="http://www.sdmx.org/resources/infomodel/1.0/keyfamily.xmi">
<eclass name="XSMeasure">
<transient/>
</eclass>
</epackage>

The ecore for this files looks like:

<eClassifiers xsi:type="ecore:EClass" name="XSMeasure" abstract="true">
<eStructuralFeatures xsi:type="ecore:EReference" name="Code" lowerBound="1" eType="ecore:EClass
codelist.ecore#//Code"/>
<eStructuralFeatures xsi:type="ecore:EReference" name="MeasureTypeDimension" lowerBound="1"
eType="#//MeasureTypeDimension"/>
</eClassifiers>

The class XSMeasure has no superclass and contains only two uni-directional many-to-one references
to other classes which are navigable only from XSMeasure.

I would expect XSMeasure not to be included in the hibernate mapping which Teneo generates but it
always appears on re-generation.

Other elements within the annotations.xml file are working as expected but never the Transient tag.

Is this the correct syntax Im using here ?

Any help is appreciated.

Duncan

Forgot to add, the class XSMeasure does not 'contain' the features it references.

Hi Duncan,
I have tested this and it worked fine with me, the xml example I use:

<epackage namespace-uri=" http://www.eclipse.org/emf/teneo/samples/emf/annotations/tra nsent">

<eclass name="Body">
<property name="theID">
<id/>
</property>
</eclass>

<eclass name="Head">
<transient/>
</eclass>

</epackage>

Which Teneo version are you on?

Btw, I have added the behavior that if an ereference references a transient eclass that then the
ereference is also set to transient. This will be in a new release.

Hi Martin,
My setup is EMF 2.2, Teneo 0.75, Hibernate 3.3, JDK1.5

Ive tried the transient on a few different classes now always with the same results. Im making sure
that the annotations.xml is being picked up correctly.

My assumption was that there was some issue with references but I understood that only bidirectional
references could prevent the transient class from not being persisted.

Hi Duncan,
Can you debug into the DefaultAnnotator class and then the processClass method? For your transient
eclass the aClass parameter should have a member called transient with a Transient object. If not
then I know something is wrong in the annotation parsing.

Btw, Teneo 0.7.5 has a test for transient but it uses the @Transient annotation in the eannotation.
The test I mentioned below is on 0.8.0 for which I added also a transient annotation test with xml.

Hi Martin,
yes I already debugged into the processClass method and I can see that
their is a Transient object in the transient member variable for this class.
It would appear that it is picking it up ok from the annotations file but then somehow
it is getting lost.

Looking again.....I did notice in the processClass method at line 290 there is a check
to see if the class is Transient and it uses the getEAnnotation method on the annotated
class and uses the key "http://ejb.elver.org/Transient", but when I debug into this method
the eAnnotations list within the annotated class is empty and it drops straight out and
continues to process as normal.

regards

Duncan

Hi Duncan,
Is the entity member of the transient aClass set with an Entity instance? In case of a transient
eclass the defaultannotator should not set an entity instance in the aClass.

Can you also debug into the class HibernateMappingGenerator and then the method: processPAClass.
There the transient eclass should be ignored because it should not have the entity set.

Hi Martin,
the entity (entity: org.eclipse.emf.teneo.annotations.pannotation.Entity ) member of the aClass is
null at the start of processClass but it does get set at line 312 therefore the
class does get processed once it reached HibernateMappingGenerator.processPAClass.


I did notice that if I add an eAnnotation to the ecore file (Source=teneo.jpa value=@Transient)
and debug into DefaultAnnotator.processClass then the annotated class does have
an entry in the eAnnotations list (whereas it doesnt when only using the annotations.xml file).

When processing hits line 290 and drops in the getEAnnotation method on the annotated class
it processes further into the method than before but again drops out because it cannot
find an annotation with the source="http://ejb.elver.org/Transient". The only annotation
in the list has source="teneo.jpa"

regards

Duncan

Hi Duncan,
The xml is not translated into an eannotation but directly into the Transient instance being set in
the aClass.
There is a method call to: isMappableAnnotatedClass in the processAClass, if the aClass has
getTransient() != null then isMappableAnnotatedClass should return false, and no entity should be set.

Are you on the latest 0.7.5 release?

Hi Martin,
that was it. I updated to the new build of 0.75 (Apr22) and it worked.
I can see the updated code in the processClass method which now deals with
Transient.

again, Many thanks.

Forgot to add, the class XSMeasure does not 'contain' the features it references.

Hi Duncan,
I have tested this and it worked fine with me, the xml example I use:

<epackage namespace-uri=" http://www.eclipse.org/emf/teneo/samples/emf/annotations/tra nsent">

<eclass name="Body">
<property name="theID">
<id/>
</property>
</eclass>

<eclass name="Head">
<transient/>
</eclass>

</epackage>

Which Teneo version are you on?

Btw, I have added the behavior that if an ereference references a transient eclass that then the
ereference is also set to transient. This will be in a new release.

Hi Martin,
My setup is EMF 2.2, Teneo 0.75, Hibernate 3.3, JDK1.5

Ive tried the transient on a few different classes now always with the same results. Im making sure
that the annotations.xml is being picked up correctly.

My assumption was that there was some issue with references but I understood that only bidirectional
references could prevent the transient class from not being persisted.

Hi Duncan,
Can you debug into the DefaultAnnotator class and then the processClass method? For your transient
eclass the aClass parameter should have a member called transient with a Transient object. If not
then I know something is wrong in the annotation parsing.

Btw, Teneo 0.7.5 has a test for transient but it uses the @Transient annotation in the eannotation.
The test I mentioned below is on 0.8.0 for which I added also a transient annotation test with xml.

Hi Martin,
yes I already debugged into the processClass method and I can see that
their is a Transient object in the transient member variable for this class.
It would appear that it is picking it up ok from the annotations file but then somehow
it is getting lost.

Looking again.....I did notice in the processClass method at line 290 there is a check
to see if the class is Transient and it uses the getEAnnotation method on the annotated
class and uses the key "http://ejb.elver.org/Transient", but when I debug into this method
the eAnnotations list within the annotated class is empty and it drops straight out and
continues to process as normal.

regards

Duncan

Hi Duncan,
Is the entity member of the transient aClass set with an Entity instance? In case of a transient
eclass the defaultannotator should not set an entity instance in the aClass.

Can you also debug into the class HibernateMappingGenerator and then the method: processPAClass.
There the transient eclass should be ignored because it should not have the entity set.

Hi Martin,
the entity (entity: org.eclipse.emf.teneo.annotations.pannotation.Entity ) member of the aClass is
null at the start of processClass but it does get set at line 312 therefore the
class does get processed once it reached HibernateMappingGenerator.processPAClass.


I did notice that if I add an eAnnotation to the ecore file (Source=teneo.jpa value=@Transient)
and debug into DefaultAnnotator.processClass then the annotated class does have
an entry in the eAnnotations list (whereas it doesnt when only using the annotations.xml file).

When processing hits line 290 and drops in the getEAnnotation method on the annotated class
it processes further into the method than before but again drops out because it cannot
find an annotation with the source="http://ejb.elver.org/Transient". The only annotation
in the list has source="teneo.jpa"

regards

Duncan

Hi Duncan,
The xml is not translated into an eannotation but directly into the Transient instance being set in
the aClass.
There is a method call to: isMappableAnnotatedClass in the processAClass, if the aClass has
getTransient() != null then isMappableAnnotatedClass should return false, and no entity should be set.

Are you on the latest 0.7.5 release?

Hi Martin,
that was it. I updated to the new build of 0.75 (Apr22) and it worked.
I can see the updated code in the processClass method which now deals with
Transient.

again, Many thanks.
