Package org.hibernate.query.spi

Class StreamDecorator<R>

java.lang.Object

org.hibernate.query.spi.StreamDecorator<R>

All Implemented Interfaces:

AutoCloseable, BaseStream<R,Stream<R>>, Stream<R>

public class StreamDecorator<R>
extends Object
implements Stream<R>

The StreamDecorator wraps a Java Stream and registers a closeHandler which is passed further to any resulting Stream. The goal of the StreamDecorator is to close the underlying Stream upon calling a terminal operation.

Since:

5.4
