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

XAttrCodec.encodeValue介绍

[英]Encode byte[] value to string representation with encoding. Values encoded as text strings are enclosed in double quotes ("), while strings encoded as hexadecimal and base64 are prefixed with 0x and 0s, respectively.
[中]用编码将字节[]值编码为字符串表示形式。编码为文本字符串的值用双引号（\）括起来，而编码为十六进制和base64的字符串则分别以0x和0s作为前缀。
