runtime

So for this project I am trying to extend a class at runtime. What I would like to know, is this even possible? If so, how would I do it? Are there libraries out there for these things? CGLib is a library you're looking for. It's quite powerfull in extending classes or implementing interfaces in runtime, so many popular frameworks, like Spring or Hibernate use it. You can create class extension with code like public Object createProxy(Class targetClass) { Enhancer enhancer = new Enhancer(); enhancer.setSuperclass(targetClass); enhancer.setCallback(NoOp.INSTANCE); return enhancer.create(); }

This is a continuation of the question posted in: How to load a jar file at runtime I am uncertain as to how to continue to the method invocation level. From my understanding, from the clazz object, I would used getMethod or getDeclaredMethod to get a Method object from which I would call invoke. Of course, invoke requires an instance. Would that then be what is called doRun in the example code? Do I need to perform the doRun.run() method call even though I want to execute a different method than main (assuming that it is main on the doRun object that is called with the run invocation)? Just

提到.Net的时候，大多数人的第一反应可能就是.Net Framework和Visual Studio。.Net Framework的第一个版本发布与2002年2月13日，这对于科技发展日新月异的时代，这差不多已经可以看做是史前文明了。 .Net Framework发布之后，微软就一直致力于让它成为现代Web、移动和云时代的可用性开发平台。这也促成了.Net Core 2和.Net Standard 2.0的发展，但是这种快速发展也往往让人们开始对庞大的.Net 生态系统感到困惑。 .Net生态系统混乱 我们都知道.Net框架，但是它是如何在基类库中工作的呢？什么是便携式类库？什么时候使用？.Net Core又是什么呢？与.Net Framework有什么不同呢？什么又是.Net Standard？如何安装？如何建立一个可重用的库呢？ 上面的所有因素都会在你为项目选择的时候造成困扰。什么是.NET标准类库，.NET Core或.NET Framework？什么是共享项目和可移植类库？你应该在哪里集中精力？是否应该学习一切，放弃旧知识？如何选用runtime？……这些都是在开始下个项目或者学习新技术之前都需要了解的关键问题，所以本文将尽力在文中回答这些问题。 .NET生态系统解释 为了满足现代应用的需求，.Net生态系统正在经历不断的升级改造，下图是.Net生态系统的现状：

** * 执行一个shell命令，并返回字符串值 * * @param cmd * 命令名称&参数组成的数组（例如：{"/system/bin/cat", "/proc/version"}） * @param workdirectory * 命令执行路径（例如："system/bin/"） * @return 执行结果组成的字符串 * @throws IOException */ public static synchronized String run(String[] cmd, String workdirectory) throws IOException { StringBuffer result = new StringBuffer(); try { // 创建操作系统进程（也可以由Runtime.exec()启动） // Runtime runtime = Runtime.getRuntime(); // Process proc = runtime.exec(cmd); // InputStream inputstream = proc.getInputStream(); ProcessBuilder builder = new ProcessBuilder(cmd); InputStream in = null; // 设置一个路径（绝对路径了就不一定需要） if

I have a TToolBar created in design time with no ToolButtons. My idea is to create ToolButtons in runtime and place them there when my forms are created, just to show the user what forms are opened without needing to open a "Windows" menu in the main menu. I have an unit named NavigationUtils.pas that I use to store the procedures / functions about navigation (as the creation of the buttons when my forms are created). The question is: How can I configure the OnClick event when the ToolButtons are created? From the comments it is clear that you are not assigning a TNotifyEvent to the OnClick

How can i generate bytecode (Byte[]) from a String at runtime, without using a "javac" process or something of this sort? is there a simple way of calling the compiler like that? later addition: I chose to accept the solution that actually best fits my situation . my application is a hobby-project still in design sketch phase, and it is the right time to consider inserting new technology. also, since the guy that's supposed to help me with BL is a JavaScript developer, the idea of using a JavaScript interpreter instead of a stub compiler+classLoader seems more appealing to me in this situation

In the previous versions of EF we were able to alter the dbcontext connection string as below : context.Database.Connection.ConnectionString = "the new connectionstring"; How can we do this with EF7? Thank you I found the solution : https://github.com/aspnet/EntityFramework/wiki/Configuring-a-DbContext#config-from-external-code Context Code public class BloggingContext : DbContext { public BloggingContext(DbContextOptions options) : base(options) { } public DbSet<Blog> Blogs { get; set; } } Application code var optionsBuilder = new DbContextOptionsBuilder(); optionsBuilder.UseSqlServer(@
