Package io.trino.parquet.reader.decoders

Class TransformingValueDecoders

java.lang.Object

io.trino.parquet.reader.decoders.TransformingValueDecoders

public class TransformingValueDecoders
extends Object

ValueDecoder implementations which build on top of implementations from ValueDecoders. These decoders apply transformations to the output of an underlying primitive parquet type decoder to convert it into values which can be used by ColumnAdapter to create Trino blocks.
