本文整理了Java中org.apache.hadoop.io.file.tfile.Utils.readString()方法的一些代码示例，展示了Utils.readString()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。Utils.readString()方法的具体详情如下：
包路径：org.apache.hadoop.io.file.tfile.Utils
类名称：Utils
方法名：readString

Utils.readString介绍

[英]Read a String as a VInt n, followed by n Bytes in Text format.
[中]以VInt n格式读取字符串，后跟文本格式的n字节。

public MetaIndexEntry(DataInput in) throws IOException {
 String fullMetaName = Utils.readString(in);
 if (fullMetaName.startsWith(defaultPrefix)) {
  metaName =
    fullMetaName.substring(defaultPrefix.length(), fullMetaName
      .length());
 } else {
  throw new IOException("Corrupted Meta region Index");
 }
 compressionAlgorithm =
   Compression.getCompressionAlgorithmByName(Utils.readString(in));
 region = new BlockRegion(in);
}

 for (int i = 0; i < n; i++) {
  BlockRegion region = new BlockRegion(in);
  listRegions.add(region);
 }
}
