Class LoggerStream

  java.io.OutputStream
      java.io.FilterOutputStream
          java.io.PrintStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.Appendable

public class LoggerStream
extends java.io.PrintStream

Wrap a Logger as a PrintStream. Useful mainly for porting code that previously logged to a System PrintStream or to a proxy. Calling LoggerStream.println() will call Logger.info() for Level.INFO. A call to flush() or to a println() method will flush previously written text, and complete a call to Logger. You may be surprised by extra newlines, if you call print("\n") and flush() instead of println();
