类名称:Dictionary
方法名:getValueBytesFromId

Dictionary.getValueBytesFromId介绍

[英]A lower level API, get byte values from ID, return the number of bytes written. Bypassing the cache layer, this could be significantly slower than getIdFromValue(T value).
[中]较低级别的API,从ID获取字节值,返回写入的字节数。绕过缓存层,这可能比getIdFromValue(T值)慢得多。

@Override
public boolean moveNext() throws IOException {
  if (curDictIndex < dictionaryList.size() && curKey <= curDict.getMaxId()) {
    byte[] buffer = new byte[curDict.getSizeOfValue()];
    int size = curDict.getValueBytesFromId(curKey, buffer, 0);
    curValue = Bytes.copy(buffer, 0, size);
    if (++curKey > curDict.getMaxId()) {
      if (++curDictIndex < dictionaryList.size()) {
        curDict = dictionaryList.get(curDictIndex);
        curKey = curDict.getMinId();
      }
    }
    return true;
  }
  curValue = null;
  return false;
}
