public abstract class TypeReference<T> extends Object implements Comparable<TypeReference<T>>
Comparable
(any such generic interface would do, as long as it forces a method
with generic type to be implemented).
to ensure that a Type argument is indeed given.
Usage is by sub-classing: here is one way to instantiate reference
to generic type List<Integer>:
TypeReference ref = new TypeReference<List<Integer>>() { };
which can be passed to methods that accept TypeReference.| 限定符 | 构造器和说明 |

The only reason we define this method (and require implementation
of
Comparable) is to prevent constructing a
reference without type information. |
