ing a method with a known signature, but dynamic type

So I've been very into bytecode recently, and I want to learn how to use invokedynamic. I've already figured out how to link a static method through invokedynamic, but I have a more specific use case. I want to: Pass in an arbitrary object to a method (the object has a pre-determined method-signature that I want to invoke, but the type cannot inherit an interface or be determined easi

一种具有已知签名但是是动态类型的方法

所以我最近一直非常喜欢字节码,我想学习如何使用invokedynamic。 我已经想通过invokedynamic链接一个静态方法,但我有一个更具体的用例。 我要: 将一个任意对象传递给一个方法(该对象具有一个我想调用的预定方法签名,但该类型不能继承接口或容易确定。) 然后该方法应该在该对象上调用dynamic,并调用给定的方法 目前我的引导方法如下所示: public static CallSite bootstrap(MethodHandles.Lookup caller, String

Generate Invokedynamic with Javassist

I am trying to do something relatively simple, I think. Take for example the following Java bytecode for a method doSomething(int): public java.lang.String doSomething(int i); 0 iload_1 [i] 1 invokestatic MyHelper.doSomething(int) : Java.lang.String 4 areturn This bytecode pretty much only forwards the call to a static helper. What I want to do now is to replace the invokestatic with invoked

用Javassist生成Invokedynamic

我想,我正在尝试做一些相对简单的事情。 以一个方法doSomething(int)的下面的Java字节码为例: public java.lang.String doSomething(int i); 0 iload_1 [i] 1 invokestatic MyHelper.doSomething(int) : Java.lang.String 4 areturn 这个字节码几乎只将呼叫转发给一个静态助手。 我现在想要做的是用invoke动态替换invokestatic使用Javassist。 我知道如何用ASM来做到这一点,因此我只是假设我想知道它是如何工作的,因

invokedynamic and implicit methods

As I understand from reading this post about the new invokedynamic bytecode instruction in JDK 7, it makes it possible to call methods on the objects which are not statically defined in the object's class and have those method calls be resolved to some concrete static methods in some other class by intercepting the method call target resolution (the post gives an example). Does this mean th

invokedynamic和implicit方法

据我所知,通过阅读这篇文章,了解JDK 7中的新的invokedynamic字节码指令,它可以调用对象的方法,这些方法不是在对象的类中静态定义的,并且可以将这些方法调用解析为某些具体的静态方法其他类通过拦截方法调用目标分辨率(帖子举例)。 这是否意味着Java 7类可以具有像Scala一样的隐式方法? 如果不是,Scala中的隐式方法解析与invokedynamic方法解析有什么不同? 这完全不相关。 scala中的含义在编译时完全解决 。 编

Send SMS on Android

I made a java class to send sms but I have a problem when I call the class more than once in the same service. The messages are sent perfect, but as you can see in my class I have a PendingIntent listening when sending the messages and their status (whether successfully or there was error). The problem is: if I call twice to the same class, those two times the BroadcastReceiver receives the

在Android上发送短信

我做了一个java类来发送短信,但当我在同一个服务中多次调用该类时,我遇到了问题。 这些消息发送完美,但正如您在我的课程中所看到的,发送消息及其状态(无论是否成功或发生错误)时,我都有一个PendingIntent侦听。 问题是: 如果我给同一个班级打两次电话,这两次BroadcastReceiver收到相同的信息。 例如:如果我打电话给班级两次,而其中一次出货有错误。 两个BroadcastReceiver收到相同的错误,或两者都收到,就

Rounded buttons

I want to have something like this five buttons, one button surrounded by four other buttons. Just like this: I know that with Android that we can only have square type views so how would it be possible to do this? OpenGl or something? Anyone have any links to something related? Basically I want curved buttons that are close together. My guess is that at the end of the day it will be easi

圆形按钮

我想要这样的五个按钮,其中一个按钮由四个其他按钮环绕。 像这样: 我知道,使用Android,我们只能使用方形视图,因此如何才能做到这一点? OpenGl什么的? 任何人有任何相关的链接? 基本上我想要弯曲的按钮靠得很近。 我的猜测是,在一天结束时,在自定义视图中执行此操作会更容易。 但如果你想使用股票的意见,我会建议如下。 首先,使用RelativeLayout容器将四个外部按钮排列在2x2网格中。 然后放置中心按钮,

Android How to calculate network usage packet/data

Now a days Internet access is very costly.The provider used charges like hell. We do not use unlimited plan for internet.That's why I would like to develop an that can facilities to calculate(manage) network package/data usage. Suppose I have activated 5GB data plan.So I need to check before surfing net,upload/download things. I know some Data provider provides these facility .I want to

Android如何计算网络使用数据包/数据

现在一天上网费用非常高昂。提供商使用地狱般的费用。 我们不使用无限制的互联网计划。这就是为什么我想开发一个可以计算(管理)网络包/数据使用情况的工具。 假设我已经激活了5GB的数据计划。所以我需要在上网之前检查,上传/下载东西。 我知道一些数据提供商提供这些设施。我想通过我的应用程序捕获我的Android设备上的网络数据包。 但是,我怎样才能将其写入我自己的代码中。 任何帮助将不胜感激。 谢谢你的提前 请

Find a matrix which satisfies certain constraints

Another description of the problem: Compute a matrix which satisfies certain constraints Given a function whose only argument is a 4x4 matrix ( int[4][4] matrix ), determine the maximal possible output (return value) of that function. The 4x4 matrix must satisfy the following constraints: All entries are integers between -10 and 10 (inclusively). It must be symmetrix, entry(x,y) = entry(y

找到满足一定约束的矩阵

对问题的另一种描述:计算满足一定约束条件的矩阵 给定一个函数,其唯一参数是一个4x4矩阵( int[4][4] matrix ),确定该函数的最大可能输出(返回值)。 4×4矩阵必须满足以下约束条件: 所有条目都是-10到10之间的整数(包含)。 它必须是symmetrix,entry(x,y)= entry(y,x)。 对角线条目必须是正数,条目(x,x)> 0。 所有16个条目的总和必须为0。 该函数只能总结矩阵的值,没有什么奇特的。 我的

Bamboo Deployment with generated Jenkins artifacts

I am doing analysis of Bamboo to Jenkins migration. We have Jenkins build ready, and artifacts are staged at specified server location. My question is, can I use Bamboo deploy plan for generated Jenkins artifacts, by specifying artifacts location? I tried to explore at Bamboo side using different plugins for deployment plan tasks, but cannot see any option for giving source path of artifacts

使用生成的Jenkins工件进行Bamboo部署

我正在分析竹子到詹金斯的迁移。 我们已经准备好了Jenkins,并且在指定的服务器位置上展示了工件。 我的问题是,我可以使用Bamboo部署计划生成詹金斯工件,通过指定工件位置? 我尝试在Bamboo方面使用不同的插件来部署计划任务,但是看不到任何选择需要部署的工件的源路径。 任何帮助真的很感激 我们不会采用这种方法,但经过大量分析后,我发现下面的解决方案= 在您的Bamboo部署计划中创建SSH任务 在此SSH任务中,

junit test runs OK locally and in jenkins but not in bamboo

I have 1 test case which is running OK locally (both in maven from console and directly from the IDE) and in our jenkins server. But when we run it in Bamboo (we are migrating our builds to Bamboo) I am not getting the expected assertion result. The test expect a CommitException to be thrown for invalid input, eg negative amount. The special thing with the test input causing the anomaly is t

junit测试可以在本地和jenkins运行,但不能运行在竹子上

我有1个测试用例在本地运行(在控制台的maven中以及直接从IDE中运行)以及我们的jenkins服务器中。 但是当我们在Bamboo中运行它时(我们将我们的构建迁移到Bamboo),我没有得到预期的断言结果。 测试期望针对无效输入抛出CommitException,例如负数。 测试输入引起异常的特殊情况是它是负值。 代码片段是: @SuppressWarnings("unused") private static Object[] randomInvalidAmounts() { //The test parameters ar

Place detail request failing

I have a small java app that, given a list of references for google places, must get back the Id's for each of said google places (long story short, we were storing references for places instead of their Id's, and only now realized that references are not unique per place). My app works perfectly for about 95% of the places in the list, but fails with a "NOT_FOUND" status code

放置详细信息请求失败

我有一个小的java应用程序,给定一个谷歌地方的参考列表,必须取回每个所述谷歌地点的Id(长话短说,我们存储的地方,而不是他们的ID的引用,只有现在才意识到,引用每个地方都不是唯一的)。 我的应用程序完美适用于列表中大约95%的位置,但对于某些记录而言失败时会显示“NOT_FOUND”状态码。 某些调查显示,这些特定地点的地点参考(如果与https://maps.googleapis.com/maps/api/place/details/json?sensor=false&key=m
