Methods in io.trino.parquet.reader with parameters of type Field

Modifier and Type	Method	Description
static void	ListColumnReader.calculateCollectionOffsets(Field field, it.unimi.dsi.fastutil.ints.IntList offsets, it.unimi.dsi.fastutil.booleans.BooleanList collectionIsNull, int[] definitionLevels, int[] repetitionLevels)	Each collection (Array or Map) has four variants of presence: 1) Collection is not defined, because one of it's optional parent fields is null 2) Collection is null 3) Collection is defined but empty 4) Collection is defined and not empty.
