[Xpand / Xtend] typeSelect() on stereotype does not work [message #641832]

Hi,

after successfully accessing my Profie in Xpand/Xtend I was wondering how to enable my stereotypes as regular types, so that typeSelect can recognize them?

I have a sample model where one class has the stereotype of "Form". Now I want in xTend do be able to do this

e.eContents.typeSelect(Form)

But currently this does not work. He only finds "Class" as a type, which has "Form" as an applied stereotype.

As far as I can see, the Hibernate Cartridge also has Entity as a stereotype but manages to work with Entity as a type.

I tried to test with the Persistence.profile.uml and the example-model.uml whether I could select all Entities with

e.eAllContents.typeSelect(Entity)

but it did not work either.

So I am thinking there is some option I have to enable to make it work in my project.

Does someone know what I have to do?

Currently I have the following and I get an error, that main for uml::Class is not defined. It is because I am getting back Elements of type "Class" instead of "Form".

List[Form] forms(Model this) :
    this.eContents.typeSelect(Class).select(e|e.getAppliedStereotype("Forms::Form") != null);

«DEFINE main FOR Model»
	«EXPAND main FOREACH forms()»
«ENDDEFINE»

«DEFINE main FOR Form»
	«FILE name+".java"»
		public class «name» {
			
		}
	«ENDFILE»
«ENDDEFINE»

Here you go:

<?xml version="1.0"?>
<workflow>
	<property name="model" value="muba.googleforms/src/model/Sample.uml" />
	<property name="profile" value="muba.googleforms/src/model/Forms.profile.uml" />
	<property name="src-gen" value="src-gen" />
	
	
	<bean class="org.eclipse.xtend.typesystem.uml2.Setup" standardUML2Setup="true" />
	
	<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup" platformUri=".."/>
	
	<!-- instantiate metamodel -->
	<bean id="mm" class="org.eclipse.xtend.typesystem.emf.EmfRegistryMetaModel"/>

	<!-- Profile Model -->

Hi,

i use a workflow that looks like this

<workflow>
	
	<bean class="org.eclipse.xtend.typesystem.uml2.Setup" standardUML2Setup="true" />
	
	<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup" platformUri=".." />
	
	<component class="org.eclipse.emf.mwe.utils.Reader">
		<uri value="platform:/resource/xpand.uml.profile.sample/src/model/test.uml" />
		<modelSlot value="model" />
	</component>
	
	<component class="org.eclipse.emf.mwe.utils.DirectoryCleaner">
		<directory value="src-gen" />
	</component>
	
	
	<component class="org.eclipse.xpand2.Generator">
		<metaModel class="org.eclipse.xtend.typesystem.uml2.profile.ProfileMetaModel">
			<profile value="platform:/resource/xpand.uml.profile.sample/src/model/test.profile.uml" />
		</metaModel>
		<metaModel class="org.eclipse.xtend.typesystem.uml2.UML2MetaModel" />
		<expand value="template::Template::main FOR model" />
		<outlet path="src-gen" >
			<postprocessor class="org.eclipse.xpand2.output.JavaBeautifier" />
		</outlet>
	</component>
	

</workflow>

this works together with a template like

«EXTENSION template::GeneratorExtensions»

«DEFINE main FOR uml::Model»
	«EXPAND main FOREACH this.eAllContents.typeSelect(test::Bean)»
«ENDDEFINE»
«DEFINE main FOR test::Bean»
«FILE getFQPN().replaceAll("\\.","/")+"/"+name+".java"»
package «getFQPN()»;
public class «name» {

}
«ENDFILE»
«ENDDEFINE»

«DEFINE main FOR uml::Element»
«ENDDEFINE»
