Class LoggingOutputStream

      java.io.ByteArrayOutputStream
          info.aduna.autofocus.util.LoggingOutputStream

All Implemented Interfaces:

Closeable, Flushable

public class LoggingOutputStream
extends ByteArrayOutputStream

An OutputStream that writes contents to a Logger upon each call to flush().

This code was derived from code found at http://blogs.sun.com/nickstephen/entry/java_redirecting_system_out_and, changing the use of java.util.logging with SLF4J.

Warning: when using this class to redirect System.out and System.err to a Logger, take extreme care that the Logger specified to the constructor does not print to System.out or System.err (as e.g. the SimpleLogger does), or you will run into an infinite loop.
