用java编写综合/桥接方法

发布于 2024-11-25 00:48:08 字数 429 浏览 1 评论 0原文

我正在编写一个应用程序来检查该方法是合成的还是桥接的。为了测试这个应用程序，我在我的存根中添加了各种方法。但对于任何方法来说，测试用例中都没有覆盖这个块。 Stub 包含 validate(Object o) 等方法，就像任何其他普通的 java 类一样。

我应该在我的存根中添加什么样的方法才能覆盖这一行？

代码：

     Method[] methods = inputClass.getMethods();
        for (Method method : methods) {

        if (method.isSynthetic() || method.isBridge()) {
            isInternal = true;
        }
       // More code.
     }

I am writing an application which checks if the method is sythentic or bridge.
For testing this application I have added various methods in my stub.
But for none of the method this block is getting covered in the test case.
Stub contains methods like validate(Object o) ,etc its just like any other normal java class.

What kind of method should I add in my stub so this line will get covered?

code :

     Method[] methods = inputClass.getMethods();
        for (Method method : methods) {

        if (method.isSynthetic() || method.isBridge()) {
            isInternal = true;
        }
       // More code.
     }

Java 中的桥接方法是合成方法，是实现某些 Java 语言功能所必需的。最著名的示例是协变返回类型和泛型中的情况，即基本方法参数的擦除与所调用的实际方法不同。

import java.lang.reflect.*;

/**

class SampleTwo {

    public static class A<T> {

        public T getT(T args) {
            return args;
        }
    }

    static class B extends A<String> {

        public String getT(String args) {
            return args;
        }
    }
}

public class BridgeTEst {

    public static void main(String[] args) {
        test(SampleTwo.B.class);
    }

    public static boolean test(Class c) {
        Method[] methods = c.getMethods();
        for (Method method : methods) {

            if (method.isSynthetic() || method.isBridge()) {
                System.out.println("Method Name = "+method.getName());
                System.out.println("Method isBridge = "+method.isBridge());
                System.out.println("Method isSynthetic = "+method.isSynthetic());
                return  true;
            }
        // More code.
        }
        return false;
    }
}

Bridge methods in Java are synthetic methods, which are necessary to implement some of Java language features. The best known samples are covariant return type and a case in generics when erasure of base method's arguments differs from the actual method being invoked.

import java.lang.reflect.*;

/**
 *
 * @author Administrator
 */
class SampleTwo {

    public static class A<T> {

        public T getT(T args) {
            return args;
        }
    }

    static class B extends A<String> {

        public String getT(String args) {
            return args;
        }
    }
}

public class BridgeTEst {

    public static void main(String[] args) {
        test(SampleTwo.B.class);
    }

    public static boolean test(Class c) {
        Method[] methods = c.getMethods();
        for (Method method : methods) {

            if (method.isSynthetic() || method.isBridge()) {
                System.out.println("Method Name = "+method.getName());
                System.out.println("Method isBridge = "+method.isBridge());
                System.out.println("Method isSynthetic = "+method.isSynthetic());
                return  true;
            }
        // More code.
        }
        return false;
    }
}
