在Blackberry Java中捕捉Throwable:好主意吗? [英] Catching Throwable in Blackberry Java: Good Idea?

问题描述

我经常在Blackberry文档中看到Throwable的catch子句，例如

I often see catch clauses for Throwable in Blackberry documentation, such as the Network API docs. My sense is that this is not generally a good practice in Java.

在Blackberry编程中是否有这个原因?

Is there a reason for this in Blackberry programming?

是否与堆栈跟踪生成适用于Throwables?

Does it have to do with stack trace generation for Throwables?

推荐答案

当您在BlackBerry应用程序中捕获Throwable时，它不仅保留堆栈跟踪，还将堆栈跟踪保存在设备事件日志中.

When you catch Throwable in a BlackBerry app, not only does it preserve the stack trace, it saves that stack trace in the device event log. There is no way for an app to get a stack trace itself, so unfortunately you can't automatically collect stack traces.

要查看堆栈跟踪，请拉起事件日志查看器.对于带有物理键盘的黑莓手机，请按住"Alt"，然后按L G L G调出事件日志.

To view the stack trace, you pull up the event log viewer. For blackberries with physical keyboards, hold 'Alt' and then press L G L G to bring up the event log.
