public class KLogJSONFormatter
extends Formatter

Format logging output as JSON formatted string with UUID, time stamp, logging level, code location and the logging information. The KLog.debug(), KLog.info() and KLog.error() adds the code location, delimited by KLog.DELIMITER which is then formatted here.

 Example:
 KLog.info("Program start");
 
 Output:
 {
   "KLog": [
     {
       "UUID": "dd5ff181-34bb-4f34-982d-65c8b4a0f264",
       "Logtime": "2024-06-21T18:32:54.958",
       "Level": "Information",
       "Location": "main[1]:Test:main:21",
       "Text": "Program start"
     }
   ]
 }
