本文整理了Java中org.apache.hadoop.fs.XAttrCodec类的一些代码示例，展示了XAttrCodec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。XAttrCodec类的具体详情如下：
包路径：org.apache.hadoop.fs.XAttrCodec
类名称：XAttrCodec

XAttrCodec介绍

[英]The value of XAttr is byte[], this class is to covert byte[] to some kind of string representation or convert back. String representation is convenient for display and input. For example display in screen as shell response and json response, input as http or shell parameter.
[中]XAttr的值是byte[]，这个类将把byte[]转换成某种字符串表示或转换回。字符串表示法便于显示和输入。例如，在屏幕上显示为shell响应和json响应，输入为http或shell参数。
