   I tried to define the methods, but i am not sure is it fit,  if this correct, i will create a new issuse, and if this is your concern issuse, could you please defind it, because you are more professional!
   
   MultiLevelSkipListWriter
   
    ```
   /**
      * Writes the length of a level to the given output.
      *
      * @param levelLength the length of a level
      * @param output the IndexOutput the length shall be written to
      */
     protected void writeLevelLength(long levelLength,IndexOutput output) throws IOException{
       output.writeVLong(levelLength);
     }
   
     /**
      * Writes the child pointer of a block to the given output.
      *
      * @param childPointer block of higher level point to the lower level
      * @param skipBuffer the skip buffer to write to
      */
     protected void writeChildPointer(long childPointer, DataOutput skipBuffer) throws IOException{
       skipBuffer.writeVLong(childPointer);
     }
   ```
   
   
   MultiLevelSkipListReader
   
   ```
   /**
      * read the length of the current level.
      *
      * @param skipStream the IndexInput the length shall be read from
      * @return level length
      */
     protected long readLevelLength(IndexInput skipStream) throws IOException {
       return skipStream.readVLong();
     }
   
     /**
      * read the child pointer.
      *
      * @param skipStream the IndexInput the child pointer shall be read from
      * @return child pointer
      */
     protected long readChildPointer(IndexInput skipStream) throws IOException {
       return skipStream.readVLong();
     }
   ```
