public class TimeStampPrintWriter

extends java.io.PrintWriter

This is a PrintWriter that adds a timestamp whenever println() is called It can be subclassed to provide timestamps with different formatting. This is done by overriding the method formatTimeStamp(). By default formatTimeStamp() calls getCannonicalFormat().

Constructor Summary

TimeStampPrintWriter(java.io.Writer out, boolean autoFlush)
uses out as the underlying output stream with/without autoflushing

TimeStampPrintWriter(java.io.Writer out)
uses out as the underlying stream without autoflushing

TimeStampPrintWriter(java.io.OutputStream out)
uses out as the underlying stream without autoflushing

TimeStampPrintWriter(java.io.OutputStream out, boolean autoFlush)
uses out as the underlying output stream with/without autoflushing

Method Summary

java.lang.String	formatTimeStamp() Override this method for custom timestamps
java.lang.String	getCannonicalFormat() returns a timestamp in the cannonical format
java.lang.String	getCompactFormat() returns the timestamp in a compact format, i.e.
static void	main(java.lang.String[] args)
void	print(java.lang.String s) overrides the superclass print(), by adding a timestamp
