    Description copied from class: FieldComparator
    
    Set a new AtomicReaderContext. All subsequent docIDs are relative to the current reader (you must add docBase if you need to map it to a top-level docID).
    
    Specified by:
    
    setNextReader in class FieldComparator<T extends Number>
    
    Parameters:
    
    context - current reader context
    
    Returns:
    
    the comparator to use for this segment; most comparators can just return "this" to reuse the same comparator across segments
    
    Throws:
    
    IOException - if there is a low-level IO error
