Class LogOutputStream

java.lang.Object
  java.io.OutputStream
      rice.environment.logging.LogOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

public class LogOutputStream

extends java.io.OutputStream

This class constructs an output stream that will send its output to a logger, line by line. This could for example be wrapped in a PrintStream to capture stdout or stderr to the log. As so: System.setOut(new PrintStream(new LogOutputStream(environment, Logger.INFO, "out"), true)); System.setErr(new PrintStream(new LogOutputStream(environment, Logger.INFO, "err"), true));
