1. case class AndIndexPredicate[Entry <: RowGroupIndexEntry](indexPredicates: IndexEntryPredicate[Entry]*) extends IndexEntryPredicate[Entry] with Product with Serializable

2. class FlatGenotypeReferenceFolder extends ReferenceFolder[FlatGenotype]

3. class IDRangeIndex extends RowGroupIndex[IDRangeIndexEntry]

   And identifier-range index is an index on both genomic ranges and sample identifiers simultaneously -- a pair of (sample-identifier, genomic-range) is associated with a single row group of a Parquet file in a single IDRangeIndexEntry, and a set of IDRangeIndexEntry values are collected (in memory) into an IDRangeIndex.

4. case class IDRangeIndexEntry(path: String, rowGroupIndex: Int, id: String, range: ReferenceRegion) extends RowGroupIndexEntry with Product with Serializable

5. class IDRangeIndexGenerator[T <: IndexedRecord] extends Logging

6. case class IDRangeIndexPredicate(queryRange: Option[ReferenceRegion], queryIDs: Option[Set[String]] = scala.None) extends IndexEntryPredicate[IDRangeIndexEntry] with Product with Serializable

7. class IDRangeIndexWriter extends RowGroupIndexWriter[IDRangeIndexEntry]

8. trait IndexEntryPredicate[Entry <: RowGroupIndexEntry] extends Serializable

   A predicate on the entries in an index-file.

9. case class OrIndexPredicate[Entry <: RowGroupIndexEntry](indexPredicates: IndexEntryPredicate[Entry]*) extends IndexEntryPredicate[Entry] with Product with Serializable

10. case class ParquetFileMetadata(locator: FileLocator, footer: Footer, metadata: FileMetaData, requested: ParquetSchemaType, actualSchema: ParquetSchemaType) extends Product with Serializable

11. class RangeIndex extends RowGroupIndex[RangeIndexEntry]

    A range index is an index on row groups in a Parquet file, where each row group is indexed based on the range or ranges of the values within the group.

12. case class RangeIndexEntry(path: String, rowGroupIndex: Int, ranges: Seq[ReferenceRegion]) extends RowGroupIndexEntry with Product with Serializable

13. class RangeIndexGenerator[T <: IndexedRecord] extends Logging

14. case class RangeIndexPredicate(queryRange: ReferenceRegion) extends IndexEntryPredicate[RangeIndexEntry] with Product with Serializable

    Query the entries of a RangeIndex by overlap with a query range.

15. class RangeIndexWriter extends RowGroupIndexWriter[RangeIndexEntry]

16. trait ReferenceFolder[T] extends Serializable

    ReferenceFolder is a trait for folding a value (of type T) into a Sequence of ReferenceRegion values.

17. trait RowGroupIndex[Entry <: RowGroupIndexEntry] extends AnyRef

    Any index-file implementation should extend this trait.

18. class RowGroupIndexEntry extends AnyRef

    Any class which represents an entry (line?) in an index file should extend this class.

19. trait RowGroupIndexWriter[Entry <: RowGroupIndexEntry] extends AnyRef
