Generic Typing for Lists

[Frederik Schmidt]

Hi Recoder Developers,

sorry for bothering you with this. However, unfortunately im not able to find
a way to implement the following scenario.
I want to add generics to TypeReferences and New statements. So my code looks
like

HashMap map = new HashMap();

I would like to transform it to
HashMap<String, Constant=""> map = new HashMap<String, Constant="">

Unfortunately, i am unable to find a way to add generics to the typeReference
or New statement. Would be great if you could give me a hint how I could add
generics to Statements.

regards
frederik

I try to add a type annotation to a List HashMap.

Hi,

You'll first have to get the type reference.
For a "New" statement, that's just obtained through getTypeReference(). For a
"VariableDeclaration" (covers fields, parameters, and local variables), it's
also getTypeReference().

If you're sure that a TypeReference has no TypeArguments (otherwise, you
wouldn't want to add any anyway), the following approach should work:
// preparation
ASTList<TypeArgumentDeclaration> list = new
ASTList<TypeArgumentDeclaration>();
typeRef.setTypeArguments(list);

...
code to create proper typeArgs.
...
list.add(typeArg1);
list.add(typeArg2);

// don't forget the following:
typeRef.makeParentRoleValid();
changeHistory.attached(typeArg1);
changeHistory.attached(typeArg2);

Hope it helps, otherwise, don't hesitate to contact me!

Regards,
Tobias
