Interface ColumnIndex

All Superinterfaces:

FilterPredicate.Visitor<PrimitiveIterator.OfInt>

public interface ColumnIndex
extends FilterPredicate.Visitor<PrimitiveIterator.OfInt>

Column index containing min/max and null count values for the pages in a column chunk. It also implements methods of FilterPredicate.Visitor to return the indexes of the matching pages. They are used by ColumnIndexFilter.
