Hi.
Would you mind giving me a short outline of how I can add a method to a
type so that this is compliant with Eclipse's internal structure (I was
told to use ASTRewrite).
So for a type T and a method foo(), how Do I add foo() to T by rewriting
the AST (instead of using IType.addMethod(...), which takes the method in
String form.
Thanks,
Eric

See the code snippet in the help for ASTRewrite, the example gives
everything you need.

AST ast = T.getAST();
ASTRewrite rewrite = ASTRewrite.create(ast);
MethodDeclaration methodFoo = ast.newMethodDeclaration();
// set methodFoo properties, such as
methodFoo.setName(ast.newSimpleName("foo"))
for JLS3:
ListRewrite lr = rewrite.getListRewrite(T,
TypeDeclaration.BODY_DECLARATIONS_PROPERTY);
lr.insert{first,last,before,after}(methodFoo);
for JLS2 I'm not sure; I guess:
newNode = (TypeDeclaration) rewrite.createcopytarget(T);
newNode.bodyDeclaration.add(methodFoo);
rewrite.replace(node, newNode);
HTH,
Arno
