比如我们此处的,传入了一个a(int(整型))的变量,_Generic就会进行查找generic-assoc-list,是否有对int的处理,如果没有就进行查找是否有default,如果也没有就会抛出异常。 所以我们要首先知道我们会传入哪些类型,然后在_Generic(泛型)中就要对此类型的进行处理 (PS:default不是必须的!!!) 此处为C11中_Generic的示例...
本篇我们来一起看一下Spring Framework泛型集合类型GenericTypeResolver,这里我总结了以下内容: * 核心 API - org.springframework.core.GenericTypeResolver * 版本支持:[2.5.2 , ) * 处理类型相关(Type)相关方法 * resolveReturnType * resolveType * 处理泛型参数类型(ParameterizedType)相关方法 * resolveReturnType...

该方法解析如何在变量T的类型中指定类型变量mapper。
GenericTypeResolver.resolveTypeArgument 的功能 GenericTypeResolver.resolveTypeArgument 是Spring 框架提供的一个工具方法,用于在运行时解析泛型类型信息。具体来说,它可以解析一个实现了泛型接口或继承了泛型类的具体类,在实现或继承时所指定的实际泛型类型参数。
