referTo

static <T> IuType<?,? super T> referTo(IuType<?,T> referrerType,
 Iterable<TypeFacade<?,? super T>> hierarchy,
 Type referentType)

Type Parameters:

T - referrer type

Parameters:

referrerType - referrer type facade

hierarchy - referrer's type hierarchy

referentType - generic referent type to match

Returns:

inherited type facade with same erasure as the referentType
