我有一些课
public final class Response<T> {
}
我有超类
public class BaseResponse {
}
从超类我继承
public class LoginResponse extends BaseResponse{
}
稍后我创建了对象Response<LoginResponse> myResponse
,我想将此对象传递给以下方法,该方法仅适用于超类方法和字段:
public static boolean responseIsValid(Response<BaseResponse> response, Context context) {
return false;
}
我收到wrong argument type
错误。如何正确传递?
答案 0 :(得分:3)
您可以将$ touch a1 a2 a3
$ echo a* # <-- expansion, = 'echo a1 a2 a3'
a1 a2 a3
$ echo "a*" # <-- no expansion, = 'echo a*'
a*
替换为通配符Response<BaseResponse>
Response<? extends BaseResponse>
当然public static boolean responseIsValid(Response<? extends BaseResponse> response, Context context) {
return false;
}
确实延伸LoginResponse
BaseResponse
