aspect

I am working on various concepts in PostSharp. Updated: This is my program class as namespace myconstructor { class Program { static void Main(string[] args) { createfolder(); streamfolder(); } public static void createfolder() { File.Create("E:/samplefile.txt"); } public static void streamfolder() { StreamWriter sw = new StreamWriter("E:/samplestream.txt"); } } } and my aspect class as 1)some tracing aspect class : using System; using System.Collections.Generic; using System.Linq; using System.Text; using PostSharp.Extensibility; using PostSharp.Aspects.Dependencies; using PostSharp.Aspects;

从Spring 2.0开始，可以使用基于schema及@AspectJ的方式来实现AOP，本文以一个简单的实例介绍了如何以@AspectJ方式在Spring中实现AOP。由于@Aspect是基于注解的，因此要求支持注解的5.0版本以上的JDK。 环境要求： 1. Web应用 2. 有一个专门提供系统服务的Service层 我们的目标是，如果用户调用Service层中任一方法，都在其插入一个记录信息的功能。 1. 一个最简单的AOP 共有2步。 1.1 定义一个Aspect 1. package com.sarkuya.aop.aspect; 2. import org.aspectj.lang.annotation.Aspect; 3. import org.aspectj.lang.annotation.Before; 4. @Aspect 5. public class SampleAspect { 6. @Before("execution(* com.sarkuya.service..*.*(..))") 7. public void doBeforeInServiceLayer() { 8. System.out.println("====================================="); 9. System.out.println("Aop: do

Here is my sample non-working project . It contains 2 modules: aop-lib - Aspects used as lib. It contains the following classes Wrap.java - It's the annotation used to attach advice WrapDef.java - It is the definition of the above mentioned Wrap annotation. aop-app - Uses the above aspect lib DynamicLoad.java - class to load javaagent dynamically Main.java - Main class which uses Wrap annotation. Dir structure is as follows: . ├── README.md ├── aop-app │ ├── pom.xml │ └── src │ └── main │ └── java │ └── com │ └── aop │ └── app │ ├── DynamicLoad.java │ └── Main.java └── aop-lib ├── pom.xml └──

I'm using AspectJ to intercept java.net.Socket calls. I've created very simple aspect after(): call(* java.net.Socket.connect(..)) { System.out.println("Connect intercepted!"); } and aop.xml <aspectj> <aspects> <aspect name="com.iggroup.lightstreamer.nwtp.SocketExceptionLoggingAspect"/> </aspects> <weaver options="-Xlint:ignore -Xset:weaveJavaxPackages=true -Xset:weaveJavaPackages=true"> </weaver> </aspectj> When the call stack is like this, then I can see the console output: java.lang.Exception at com.iggroup.lightstreamer.nwtp.SocketExceptionLoggingAspect.ajc$after$com_iggroup_lightstreamer

What is a standard way of profiling Scala method calls? What I need are hooks around a method, using which I can use to start and stop Timers. In Java I use aspect programming, aspectJ, to define the methods to be profiled and inject bytecode to achieve the same. Is there a more natural way in Scala, where I can define a bunch of functions to be called before and after a function without losing any static typing in the process? Do you want to do this without changing the code that you want to measure timings for? If you don't mind changing the code, then you could do something like this: def
