类 TypeReference<T>

java.lang.Object

com.getui.push.v2.sdk.common.type.TypeReference<T>

所有已实现的接口:

Comparable<TypeReference<T>>

public abstract class TypeReference<T>
extends Object
implements Comparable<TypeReference<T>>

This generic abstract class is used for obtaining full generics type information by sub-classing; it must be converted to com.fasterxml.jackson.core.type.ResolvedType implementation (implemented by JavaType from "databind" bundle) to be used. Class is based on ideas from http://gafter.blogspot.com/2006/12/super-type-tokens.html, Additional idea (from a suggestion made in comments of the article) is to require bogus implementation of 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, or resolved using TypeFactory to obtain com.fasterxml.jackson.core.type.ResolvedType.
