/**
 * It's designed to provide a convenient way to parameterized the generic type (e.g. {@code List.class}).
 * 
 
 * But the returned Class by all the methods doesn't have the actual parameterized type informations. For example:
 * 
 * 
 * List<String> clazz = Clazz.ofList(String.class);
 * // clazz doesn't have the actual type parameters information. 
 * // you won't be able to get type parameter {@code String} by: cls.getTypeParameters();
 * // To save the real type parameters: you need to either:
 * Type<List<String>> type = Type.of("List<String>"); // or Type.ofList(String.class)
 * 
 * // Or
 * Type<List<String>> type = new TypeReference<List<String>>() {}.type();
