com.go.trove.log
Class LogScribe  

java.lang.Object
  com.go.trove.log.LogScribe

All Implemented Interfaces:

java.util.EventListener, LogListener

---

public class LogScribe

extends java.lang.Object

implements LogListener

LogScribe is a LogListener that writes log messages to a PrintWriter. Each message is printed to a line that is prepended with other LogEvent information. The default prepend format is as follows:

 [event type code],[date & time],[thread name],[log source name]>[one space]
 

The event type codes are " D", " I", "*W" and "*E" for debug, info, warn and error, respectively. The default date format looks like this: "1999/06/08 18:08:34.067 PDT". If there is no log source, or it has no name, it is omitted from the prepend. Here is a sample line that is written out:

  I,1999/06/08 18:08:34.67 PDT,main> Started Transaction Manager
 

Version:

20 , 01/07/02
