程序在运行时的状态是开发人员理解程序的有用信息。全知调试和基于日志的工具使开发人员能够调查程序在执行过程中任意时间点的状态。虽然这些工具可以有效地分析单个时间点的状态，但它们可能不足以理解包含各种控制流路径的方法的一般行为。在本文中，我们提出了REMViewer(重复执行方法查看器)，即一个可视化Java方法的多个执行路径的工具。该工具将每个执行路径显示在单独的视图中，以便开发人员可以首先选择感兴趣的实际执行路径，然后比较路径中局部变量的状态。
The state of a program at runtime is useful information for developers to understand a program. Omniscient debugging and logging-based tools enable developers to investigate the state of a program at an arbitrary point of time in an execution. While these tools are effective to analyze the state at a single point of time, they might be insufficient to understand the generic behavior of a method which includes various control-flow paths. In this paper, we propose REMViewer (Repeatedly-Executed-Method Viewer), or a tool that visualizes multiple execution paths of a Java method. The tool shows each execution path in a separated view so that developers can firstly select actual execution paths of interest and then compare the state of local variables in the paths.
