All Implemented Interfaces:

Closeable, Flushable, Appendable, Loggable

public class PrintWriterImpl
extends PrintWriter
implements Loggable

This class is a PrintWriter wrapper. It exports the PrintWriter methods but fowards the message to a Logger. This implementation bufferizes the data when a print method is used. The buffer and the data are always written when a println method is used. No end of line are inserted by the println methods. A line is equals to a monolog message.
