本文整理了Java中com.yahoo.text.Utf8.toString()方法的一些代码示例，展示了Utf8.toString()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。Utf8.toString()方法的具体详情如下：
包路径：com.yahoo.text.Utf8
类名称：Utf8
方法名：toString

Utf8.toString介绍

[英]Fetch a string from a ByteBuffer instance. ByteBuffer instances are stateful, so it is assumed to caller manipulates the instance's limit if the entire buffer is not a string.
[中]从ByteBuffer实例获取字符串。ByteBuffer实例是有状态的，因此如果整个缓冲区不是字符串，则假定调用者操纵实例的限制。
