      edu.udo.cs.miningmart.m4.utils.MultipleOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

public class MultipleOutputStream
extends java.io.OutputStream

A MultipleOutputStream holds several OutputStreams. Each method called by this OutputStream is forwarded to the set of OutputStreams. So you can write something to System.out and to a file.
