How to add superinterface to IType [message #259556]

Hi all,

Could anyone tell me if it is possible and how to add a superinterface to
an IType ? I've been searching for a while now but couldn't find anything
really.

Thanks in advance.

In case someone googles it :

Document doc = new Document(sourceCode);
ASTParser parser = ASTParser.newParser(AST.JLS3);
parser.setSource(doc.get().toCharArray());
CompilationUnit cu = (CompilationUnit)parser.createAST(null);
AST ast = cu.getAST();
cu.recordModifications();
TypeDeclaration type = (TypeDeclaration)cu.types().get(0);
ASTRewrite rewriter = ASTRewrite.create(ast);
ListRewrite listRewriter;
listRewriter = rewriter.getListRewrite(type,
TypeDeclaration.SUPER_INTERFACE_TYPES_PROPERTY);
listRewriter.insertLast(ast.newSimpleName("GeneratedInterface "), null);
TextEdit edits = rewriter.rewriteAST(doc, null);
try {
edits.apply(doc);
} catch (MalformedTreeException e) {
e.printStackTrace();
} catch (BadLocationException e) {
e.printStackTrace();
}
try {
t.getCompilationUnit().getBuffer().setContents(doc.get());
} catch (JavaModelException e) {
e.printStackTrace();
}

Actually the previous post is not correct, a superinterface is added to
the class but the final source code only contains the definition of the
class : package declarations and imports are erased !

Any help would be great

Found what was wrong : just a bad initialization of the document :
IType.getSource() only returns the source code of the class people should
use ICompilationUnit.getSource() instead
