How to create <? extends subtype> with JCodeModel?

Question

I've used JClass.narrow on JCodeModel to create the necessary generics for types, but I can't figure out how to generate something like this.

private Class<? extends Serializable> dataType;

How does one generate the ? extends part?

Any help would be welcome.

Answer 1

Figured it out. Here is an example of obtaining a JClass reference to Class<? extends Serializable>. Hope it helps someone.

JClass temp = codeModel.ref(Class.class).narrow(codeModel.ref(Serializable.class).wildcard());
