类 ParameterizedTypeReference<T>

java.lang.Object

cn.sexycode.util.core.cls.ParameterizedTypeReference<T>

public abstract class ParameterizedTypeReference<T>
extends Object

The purpose of this class is to enable capturing and passing a generic Type. In order to capture the generic type and retain it at runtime, you need to create a subclass (ideally as anonymous inline class) as follows:

 ParameterizedTypeReference<List<String>> typeRef = new ParameterizedTypeReference<List<String>>() {};
 

The resulting typeRef instance can then be used to obtain a Type instance that carries the captured parameterized type information at runtime. For more information on "super type tokens" see the link to Neal Gafter's blog post.
