Warning while using reflection and generics

Question

How do I rewrite this:

<T> T callMethod(String methodName, Object[] parameters) throws ... {
    ...
    return (T) SomeClass.class.getDeclaredMethod(methodName, parameterTypes).invoke(binding, parameters);
}

so it doesn't generate a warning

warning: [unchecked] unchecked cast
        return (T) SomeClass.class.getDeclaredMethod(methodName, parameterTypes).invoke(binding, parameters);
required: T
found:    Object
where T is a type-variable:
T extends Object declared in method <T>callMethod(String,Object[])

I mean the no-SupressWarnings solution.

Answer 1

I think you'll have to live with the @SuppressWarnings(...) approach since the invoke() method returns an Object. Remember that generics are erased at runtime, and reflection happens at runtime...
