Why the Validator interface is not generic in Spring 3.0

[bibodo]

While reading the reference documentation of Spring 3.0 I found the Validator interface. And I wonder why this interface is not generic. Can any body tell my why?

Hello

I am not an expert about patterns but in the Validator's API
offer a method with some relation with generics

supports

boolean supports(Class<?> clazz)

    Can this Validator validate instances of the supplied clazz?

    This method is typically implemented like so:

    return Foo.class.isAssignableFrom(clazz);

    (Where Foo is the class (or superclass) of the actual object instance that is to be validated.)

    Parameters:
        clazz - the Class that this Validator is being asked if it can validate 
    Returns:
        true if this Validator can indeed validate instances of the supplied clazz

I think it is based for a reason about design patterns, I hope some SpringSource developer would give a deeper explanation

But I suggest you do a research in Google, about when and why an interface should be Generic <T>.
