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

ByteString.byteAt介绍

[英]Gets the byte at the given index. This method should be used only for random access to individual bytes. To access bytes sequentially, use the ByteIterator returned by #iterator(), and call #substring(int,int) first if necessary.
[中]获取给定索引处的字节。此方法应仅用于对单个字节的随机访问。要按顺序访问字节，请使用#iterator（）返回的ByteIterator，必要时首先调用#substring（int，int）。
