Package io.trino.parquet.reader

Class SimpleSliceInputStream

java.lang.Object
io.trino.parquet.reader.SimpleSliceInputStream
public final class SimpleSliceInputStream extends Object
Basic input stream based on a given Slice object. This is a simpler version of BasicSliceInput with a few additional methods.

Note that methods starting with 'read' modify the underlying offset, while 'get' methods return value without modifying the state
