com.amazonaws.logging.Log.isDebugEnabled()方法的使用及代码示例
本文整理了Java中com.amazonaws.logging.Log.isDebugEnabled()方法的一些代码示例，展示了Log.isDebugEnabled()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。Log.isDebugEnabled()方法的具体详情如下：
包路径：com.amazonaws.logging.Log
类名称：Log
方法名：isDebugEnabled
Log.isDebugEnabled介绍
[英]Is debug logging currently enabled?
Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than debug.
[中]调试日志记录当前是否启用？
调用此方法以防止在日志级别高于调试级别时执行昂贵的操作（例如，String串联）。
