Class ConsumingInputStream

java.lang.Object

java.io.InputStream

no.digipost.io.ConsumingInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

public class ConsumingInputStream
extends InputStream

An InputStream getting its contents from consuming an OutputStream. The InputStream will be immediately available for reading after construction, regardless of how much data that will be produced by the OutputStream.

Constructor Detail

ConsumingInputStream

public ConsumingInputStream(ExecutorService executorService,
                            Consumer<? super OutputStream> write)

ConsumingInputStream

public ConsumingInputStream(ExecutorService executorService,
                            Function<OutputStream,S> outputStreamDecorator,
                            Consumer<? super S> write)

Parameters:

executorService - The executorService to use to start producing data which will be readable by this inputstream.

outputStreamDecorator - An Fn to wrap the outputstream to push data to. This Fn must always wrap the given OutputStream in the OutputStream returned from this Fn, i.e. the resulting OutputStream must be constructed by wrapping the given OutputStream as a constructor argument. (E.g. new ZipOutputStream(givenOutputStream).

write - The data producing logic. This Do will be given the OutputStream resulting from the outputStreamDecorator.
