Class StreamDecorator<R>

  • All Implemented Interfaces:
    java.lang.AutoCloseable, java.util.stream.BaseStream<R,​java.util.stream.Stream<R>>, java.util.stream.Stream<R>
    public class StreamDecorator<R>
extends java.lang.Object
implements java.util.stream.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.
