Annotation insert location [message #206531]

I am programmatically adding an annotation to a FieldDeclaration. I see
inconsisitent behavior depending on whether the field has existing
modifiers. If the field is defined as private String foo then the
annotation is placed on the line above the field like this:

@MyAnnotation
private String foo

If the field is defined as just String foo, then the annotation is placed
like this:

@MyAnnotation String foo

Here is some of my code used to do this:

AST ast = astRewrite.getAST();
NormalAnnotation annotation = ast.newNormalAnnotation();
annotation.setTypeName(ast.newSimpleName("MyAnnotation"));

astRewrite.getListRewrite(bodyDeclaration,
bodyDeclaration.getModifiersProperty()).insertAt(annotation, 0, null);

The same thing occurs with other BodyDeclarations such as a
TypeDeclaration. Is there a better way to go about this or is this a bug?

thanks,
Karen

There was a discussion about annotation placement in bug 82461, and a code
formatter option was introduced. If the current options don't fit your
needs, please file an enhancement request for JDT/Core.

If you think the ASTRewrite does not produce properly formatted code
according to the code formatting options, please file a bug for JDT/Core.

If the behavior is really different depending on existing modifiers, I'd say
that's a bug.

Thanks for your response, I had not seen the added preference or that
resolved bug. I have entered bug 99729 since the behavior is different
depending on existing modifiers.

Hey,
I am trying to add annotations to certain methods of a class. I am using the ASTVisitor to get hold of the MethodDeclaration object. I used the code lines you offered, but the problem, I can see no changes to the MethodDeclaration node and I can get the ASTRewrite to write anything back to the java code. Do you have any idea how to do that?? Do u have any tutorial on how to insert annotations to method and class declarations??

I tried the following but it didn't help

The only change from the already given example should be something like this.....

MethodDeclaration methodDecl= .....
ListRewrite listRewrite = astRewrite.getListRewrite(methodDecl, MethodDeclaration.MODIFIERS2_PROPERTY ).insertAt(annotation, 0, null);

Isn't this working?
