Package org.hibernate.query.spi

Class DoubleStreamDecorator

java.lang.Object

org.hibernate.query.spi.DoubleStreamDecorator

All Implemented Interfaces:

AutoCloseable, BaseStream<Double,DoubleStream>, DoubleStream

public class DoubleStreamDecorator
extends Object
implements DoubleStream

The DoubleStreamDecorator wraps a Java DoubleStream and registers a closeHandler which is passed further to any resulting Stream.

The goal of the DoubleStreamDecorator is to close the underlying DoubleStream upon calling a terminal operation.
