Class ParameterizedTypeReference<T>

java.lang.Object

org.springframework.core.ParameterizedTypeReference<T>

public abstract class ParameterizedTypeReference<T>
extends java.lang.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 as follows:

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

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