org.esa.beam.util.Debug.assertTrue()方法的使用及代码示例
本文整理了Java中org.esa.beam.util.Debug.assertTrue()方法的一些代码示例，展示了Debug.assertTrue()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.assertTrue()方法的具体详情如下：
包路径：org.esa.beam.util.Debug
类名称：Debug
方法名：assertTrue
Debug.assertTrue介绍
[英]If the condition is NOT true, and the debugging functionality is enabled, this method throws an AssertionFailure in order to signal that an internal program post- or pre-condition failed.
Use this method whenever a valid state must be ensured within your sourcecode in order to safely continue the program.
For example, the method can be used to ensure valid arguments passed to private and protected methods.
[中]如果condition为非真，并且已启用调试功能，则此方法将抛出AssertionFailure，以发出内部程序后置条件或前置条件失败的信号。
只要必须确保源代码中的有效状态才能安全地继续程序，就使用此方法。
例如，该方法可用于确保传递给私有和受保护方法的有效参数。
