ColumnIndex (Apache Parquet Column 1.17.0 API)

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.

- Method Detail
  - getBoundaryOrder
```
BoundaryOrder getBoundaryOrder()
```
    Returns:
    
    the boundary order of the min/max values; used for converting to the related thrift object
  - getNullCounts
```
List<Long> getNullCounts()
```
    Returns:
    
    the unmodifiable list of null counts; used for converting to the related thrift object
  - getNullPages
```
List<Boolean> getNullPages()
```
    Returns:
    
    the unmodifiable list of null pages; used for converting to the related thrift object
  - getMinValues
```
List<ByteBuffer> getMinValues()
```
    Returns:
    
    the list of the min values as ByteBuffers; used for converting to the related thrift object
  - getMaxValues
```
List<ByteBuffer> getMaxValues()
```
    Returns:
    
    the list of the max values as ByteBuffers; used for converting to the related thrift object
  - getRepetitionLevelHistogram
```
default List<Long> getRepetitionLevelHistogram()
```
    Returns:
    
    the unmodifiable list of the repetition level histograms for each page concatenated together; used for converting to the related thrift object
  - getDefinitionLevelHistogram
```
default List<Long> getDefinitionLevelHistogram()
```
    Returns:
    
    the unmodifiable list of the definition level histograms for each page concatenated together; used for converting to the related thrift object
