Question

I want to know the class of a generic return type of a method, something like this:

    <T> T getEntry() { System.out.println(T.class) }

The problem is, this is not a generic class, this is just a generic method, so I can’t extract the generic type from the class. What I want to achieve is knowing what concrete type the caller wants without requiring the class, like:

<T> T getEntry(Class<?> clazz);

Is that possible?

Answer 1

Well if Kylar is right I’ve to resort to:

<T> T getEntry(String name, Class<T> clazz)

I wanted to avoid the extra argument 🙁
