获取ETL文件执行后所运行的代码行 基础知识： 语言相关：Java 工具使用：Eclipse Epsilon：是一个用于建模工程的建模语言和工具的集合 这次的课题，主要与ETL（Epsilon Transformation）和EOL（Epsilon Object）语言相关，ETL继承了EOL，主要用于模型间的转换. 这个是ETL文件中语言的一个例子，该课题不需要掌握EOL和ETL的具体语法 具体做法： 1. 先根据这个引导 https://www.eclipse.org/epsilon/doc/articles/running-from-source/ 克隆Epsilon的源代码库并将plugins, features和tests三个文件夹的所有package右键完成import project. 2. 主要涉及的文件在源代码中的位置： 包名org.eclipse.epsilon.common.parse AST.java 包名org.eclipse.epsilon.eol.execute.control IExecutionListener.java 包名org.eclipse.epsilon.common.module ModuleElement.java 3. 具体思路 代码的实现流程图（最终目标是获取ETL文件执行后所运行的代码行） 为了获得Executed lines（执行的代码）需要对ETL文件的运行进行记录，ETL 运行之前会被编译为一个AST ( abstract syntax tree), 这个AST的每个节点就是ETL的module elements, 这样就可以通过查看AST的激活状态来判断运行的代码行,对于如何建立ETL和AST节点（module elements）之间的关系方法如下图所示 ETL(IEtlModule) 和 AST (Module Element)之间的关系图 ETL继承了EOL所以也继承了EolModule模块中的ExecutionListener interface接口，可以根据需要实例化这个接口的功能，在这个接口中有三个方法， 该课题主要用到的方法是 finishedExecuting(ModuleElment ast, Objct result, IEolContext context) 这个方法在每一次AST节点被调用的时候都会运行，该方法的第一个属性是ModuleElement ast，它代表着执行的last节点，所以通过标记这个节点我们就可以知道哪些ETL语句得到了运行。 而在ModuleElement中还存在一个方法叫做： getRegine()
