本文整理了Java中org.apache.uima.cas.CAS.reset()方法的一些代码示例，展示了CAS.reset()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。CAS.reset()方法的具体详情如下：
包路径：org.apache.uima.cas.CAS
类名称：CAS
方法名：reset

CAS.reset介绍

[英]Reset the CAS, emptying it of all content. Feature structures and iterators will no longer be valid. Note: this method may only be called from an application. Calling it from an annotator will trigger a runtime exception.
[中]重置CAS，清空其中的所有内容。功能结构和迭代器将不再有效。注意：此方法只能从应用程序调用。从注释器调用它将触发运行时异常。
