Class LoggerPrintStream

java.lang.Object

java.io.OutputStream

java.io.FilterOutputStream

java.io.PrintStream

org.apache.logging.log4j.io.LoggerPrintStream

All Implemented Interfaces:

Closeable, Flushable, Appendable, AutoCloseable

public class LoggerPrintStream
extends PrintStream

Logs each line written to a pre-defined level. Can also be configured with a Marker. This class provides an interface that follows the PrintStream methods in spirit, but doesn't require output to any external stream. This class should not be used as a stream for an underlying logger unless it's being used as a bridge. Otherwise, infinite loops may occur!
