With Eclipse it is possible to find all references of a method, member or class. Is it also possible to find all references to the monitor of a synchronized? If this is not possible with Eclipse then is it possible with another Java IDE? My problem is that the monitor object hat many references. A search for all references will return to many results. I will only see where are synchronized
使用Eclipse可以找到方法，成员或类的所有引用。 是否也可以找到所有对同步监视器的引用？ 如果Eclipse无法实现，那么是否可以使用另一个Java IDE？ 我的问题是监视器对象有很多引用。 搜索所有引用将返回到许多结果。 我只会看到与这个对象同步的地方。 编辑：我添加一个示例我的意思是： public class LockClass{ public synchronized void add(Object any){ } } public class AnyOther{ private LockClass lo
I am trying to JUnit Test a J2EE Web Application with NB 7.0, JUnit and the embedded Glassfish Server in a Win7Professional machine. I broke it down to just test a plain simple Hello-World Web App with a single Session Bean. I have the glasfish-embedded-static-shell.jar in my classpath, and also tried to use the glassfish-embedded-all-3.1 but it also didn't work. Now here's the code
我正在尝试JUnit在Win7Professional机器上用NB 7.0，JUnit和嵌入式Glassfish服务器测试J2EE Web应用程序。 我把它分解成只用一个Session Bean测试一个简单的Hello-World Web App。 我的classpath中有glasfish-embedded-static-shell.jar，并试图使用glassfish-embedded-all-3.1，但它也不起作用。 这里是我用来测试bean的代码： import javax.ejb.embeddable.EJBContainer; import org.junit.AfterClass; import org.junit
When I run maven install on my multi module maven project I always get the following output: [WARNING] File encoding has not been set, using platform encoding UTF-8, i.e. build is platform dependent! So, I googled around a bit, but all I can find is that I have to add: <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> ...
当我在我的多模块maven项目上运行maven install ，我总是得到以下输出： [WARNING] File encoding has not been set, using platform encoding UTF-8, i.e. build is platform dependent! 所以，我搜索了一下，但我能找到的是我必须补充： <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> ...到我的pom.xml。 但它已经存在（在父pom.xml ）。
How do I get my project's runtime dependencies copied into the target/lib folder? As it is right now, after mvn clean install the target folder contains only my project's jar, but none of the runtime dependencies. 这适用于我： <project> ... <profiles> <profile> <id>qa</id> <build> <plugins> <plugin>
如何将我的项目的运行时依赖关系复制到target/lib文件夹中？ 就像现在一样，在mvn clean install ， target文件夹只包含我的项目的jar文件，但不包含运行时依赖项。 这适用于我： <project> ... <profiles> <profile> <id>qa</id> <build> <plugins> <plugin> <artifactId>maven-dependency-plugin</artifactId&
I'm using several enum-based state machines in my Android application. While these work very well, what I am looking for is a suggestion for how to elegantly receive events, typically from registered callbacks or from eventbus messages, into the currently active state. Of the many blogs and tutorials concerning enum-based FSMs, most of them give examples of state machines that consume data
我在我的Android应用程序中使用了几个基于枚举的状态机。 虽然这些工作非常好，但我正在寻找的是关于如何优雅地接收事件（通常是从注册回调或事件总线消息）到当前活动状态的建议。 在许多关于基于枚举的FSM的博客和教程中，大多数博客和教程都提供了使用数据的状态机（例如解析器）的示例，而不是展示如何根据事件驱动这些FSM。 我使用的典型状态机有这种形式： private State mState; public enum State { SOME_STAT
This question is related to my question on existing coroutine implementations in Java. If, as I suspect, it turns out that there is no full implementation of coroutines currently available in Java, what would be required to implement them? As I said in that question, I know about the following: You can implement "coroutines" as threads/thread pools behind the scenes. You can do t
这个问题与我在Java中现有协程实现的问题有关。 如果，如我所怀疑的，事实证明，目前在Java中没有完全实现协程，那么实现它们需要什么？ 正如我在那个问题中所说的，我知道以下几点： 你可以在后台实现“协程”作为线程/线程池。 您可以在后台使用JVM字节码做一些棘手的事情，以使协程成为可能。 所谓的“达芬奇机器”JVM实现具有原语，可以使协程无需字节码操作即可完成。 对于协程也有各种基于JNI的方法。 我会依次解
I'm looking for a way to pass environment variables into a cargo container. Something like this: <plugin> <groupId>org.codehaus.cargo> <artifactId>cargo-maven2-plugin</artifactId> <configuration> <environmentVariables> <myCustomVariable>value</myCustomVariable> ... AFAIK, The cargo only allow to pass the system proper
我正在寻找一种将环境变量传递到货物集装箱的方法。 像这样的东西： <plugin> <groupId>org.codehaus.cargo> <artifactId>cargo-maven2-plugin</artifactId> <configuration> <environmentVariables> <myCustomVariable>value</myCustomVariable> ... AFAIK，货物只允许在传递系统属性和Maven提示时传递系统属性，如以下示例所示： - <contain
I don't like the idea of having to call hasNext() and next() , and seeing how I would need a loop to call those anyways, I don't really see much point in using the iterators given to us in Lists and Maps. Is it only if you need to pull one this from the list? Or, if you're taking one item from the list, and having to do that for an unmeasured amount of time? I couldn't find th
我不喜欢不得不调用hasNext()和next()的想法，并且看到我需要一个循环来调用这些循环，但我并没有真正看到使用List中给出的迭代器和地图。 只有当你需要从列表中拉出一个呢？ 或者，如果您从列表中选取一个项目，并且必须这样做的时间不可测量？ 我无法在Google或Stack上找到此信息，请帮助我。 我不是专门针对增强型for-loop（for-each循环）。 我也明白，foreach循环在性能上表现出色，但这更多的是“为什么它存在”的问
Is there any performance testing results available in comparing traditional for loop vs Iterator while traversing a ArrayList,HashMap and other collections? Or simply why should I use Iterator over for loop or vice versa? Assuming this is what you meant: // traditional for loop for (int i = 0; i < collection.size(); i++) { T obj = collection.get(i); // snip } // using iterator Iterat
在遍历ArrayList，HashMap和其他集合时比较传统的for循环与Iterator是否有任何性能测试结果可用？ 或者干脆为什么我应该使用Iterator over循环，反之亦然？ 假设这是你的意思： // traditional for loop for (int i = 0; i < collection.size(); i++) { T obj = collection.get(i); // snip } // using iterator Iterator<T> iter = collection.iterator(); while (iter.hasNext()) { T obj = iter.next();
Consider: List<String> someList = new ArrayList<String>(); // add "monkey", "donkey", "skeleton key" to someList for (String item : someList) { System.out.println(item); } What would the equivalent for loop look like without using the for each syntax? for (Iterator<String> i = someIterable.iterator(); i.hasNext();) { String item = i.next(); System.out.println(item
考虑： List<String> someList = new ArrayList<String>(); // add "monkey", "donkey", "skeleton key" to someList for (String item : someList) { System.out.println(item); } 就相当于什么for循环看起来像不使用每个语法？ for (Iterator<String> i = someIterable.iterator(); i.hasNext();) { String item = i.next(); System.out.println(item); } 请注意，如果你需要使用i.remove()
