public void reset()
           throws IOException
```
    Description copied from interface: ResettableRowBuffer.ResettableIterator
    
    Re-initialize the iterator, start from begin row.
    
    Specified by:
    
    reset in interface ResettableRowBuffer.ResettableIterator
    
    Throws:
    
    IOException
  - close

public void close()
```
    Specified by:
    
    close in interface AutoCloseable

    close in interface Closeable
  - advanceNext
```
public boolean advanceNext()
```
    Description copied from interface: RowIterator
    
    Advance this iterator by a single row. Returns `false` if this iterator has no more rows and `true` otherwise. If this returns `true`, then the new row can be retrieved by calling RowIterator.getRow().
    
    Specified by:
    
    advanceNext in interface RowIterator<BinaryRowData>
  - getRow
```
public BinaryRowData getRow()
```
    Description copied from interface: RowIterator
    
    Retrieve the row from this iterator. This method is idempotent. It is illegal to call this method after [[advanceNext()]] has returned `false`.
