本文整理了Java中org.esa.beam.util.Debug类的一些代码示例，展示了Debug类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Debug类的具体详情如下：
包路径：org.esa.beam.util.Debug
类名称：Debug

Debug介绍

[英]The Debug as it name says is a utility class for debugging. It contains exculisvely static methods and cannot be instantiated.

This class provides methods for program assertions as well as tracing capabilities. The tracing output can be redirected to any java.io.XMLCoder. The debbuging capabilities of this class can be disabled at runtime by calling Debug.setEnabled(false).

The methods defined in this class are guaranteed not to throw any exceptions caused by illegal argument passed to them.
[中]顾名思义，Debug是一个用于调试的实用程序类。它包含非常静态的方法，无法实例化。
此类提供程序断言的方法以及跟踪功能。跟踪输出可以重定向到任何java.io.XMLCoder。可以在运行时通过调用Debug.setEnabled(false)禁用该类的去bug功能。
此类中定义的方法保证不会抛出由传递给它们的非法参数引起的任何异常。
