What is best way to get reference of JvmAnnotationType in inference? [message #904208] Mon, 27 August 2012 22:19 Go to next message

JvmTypesBuilder seems not to support JvmAnnotationType.

So I created it myself:
val annoType = createJvmAnnotationType =>[
	it.packageName = "java.lang"
	it.simpleName = "SuppressWarnings"
]

var annoTypeRef = createJvmAnnotationReference => [
	annotation = annoType
	values += createJvmStringAnnotationValue => [
		values += "all"
	]
]


It causes dangle problem, because this reference is not contained by resource.

I tried to inspect, but it seems to I am wandering so deep and internal mechanism.

Can anyone suggest best approach?

Did you try a clean build?

I think I did not explain my problem correctly.

I'm writing a JVM model inferrer,
I want to add an annotation(@SuppressWarning("all")) to my inferred type.

JvmTypesBuilder xtend extensions provides newTypeRef() method to create or reuse JvmTypeReference easily.
But it supports only against of JVMGenericType, not JvmAnnotationType.

So I tried to create JvmAnnotationReferernce by myself.

val annoType = createJvmAnnotationType =>[
	it.packageName = "java.lang"
	it.simpleName = "SuppressWarnings"
]

var annoTypeRef = createJvmAnnotationReference => [
	annotation = annoType
	values += createJvmStringAnnotationValue => [
		values += "all"
	]
]


in above code, annoTypeRef is not contained by any resource, because I didn't. (because I don't know which resource is appropriate)

So inferring causes an error log which reports isolated model from resourceset problem.

I tried to inspect JVMTypesBuilder and TypeReferences,
It's to complex to me,
So I think that I may going wrong way or too deep.

It was done by using TypeReferences

var rootType = root.toClass(typeName)[
	annotations += createJvmAnnotationReference => [
		it.annotation = references.findDeclaredType(typeof(SuppressWarnings), root) as JvmAnnotationType
		it.values += createJvmStringAnnotationValue => [
			values += "all"
		]
	]
]

Thanks for the solution, I was looking for it!
However, I'm facing another similar issue with a JvmTypeReference: I need a "void"-kind JvmTypeReference for the return type of a method I'm inferring, but I keep getting various errors when testing the plugin.
Anyone has any insight?
Edit: for some strange reason one of my previous forum searches got stuck and I couldn't find other relevant posts.
Found the solution here.
Sorry for the inconvenience.
