示例1: Reader

 * @param in The stream to read from.
 * @param logVersion The version of the data coming from the stream.
 */
public Reader(DataInputStream in, StreamLimiter limiter, int logVersion) {
  this.logVersion = logVersion;

  }
  // It is possible that the logVersion is actually a future layoutversion
  // during the rolling upgrade (e.g., the NN gets upgraded first). We
  // assume future layout will also support length of editlog op.
