The LoggingEventVO class is used to transfer information about a LoggingEvent to remote clients, in particular remote management tools. This class is not intended to be used directly by application code.

Here's an example of how you could use the LoggingEventVO class to print out information about a LoggingEvent:

import ch.qos.logback.classic.Logger;
import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.classic.spi.LoggingEventVO;

public class Example {
    public static void main(String[] args) {
        LoggerContext context = new LoggerContext();
        Logger logger = context.getLogger("example");
        logger.info("This is an example message.");
        ILoggingEvent event = context.getLastEvent();
        LoggingEventVO eventVO = new LoggingEventVO(event);

        System.out.println("Logger name: " + eventVO.getLoggerName());
        System.out.println("Level: " + eventVO.getLevel());
        System.out.println("Time stamp: " + eventVO.getTimeStamp());
        System.out.println("Thread name: " + eventVO.getThreadName());
        System.out.println("Message: " + eventVO.getFormattedMessage());
    }
}

In this example, we first create a LoggerContext and retrieve a logger named "example". We then log an example message using the info method.

After that, we retrieve the last logged event from the context using the context.getLastEvent() method and create an instance of LoggingEventVO passing the event as an argument.

We then print out the logger name, level, timestamp, thread name and message of the event by calling the corresponding getter method on the LoggingEventVO instance.

As I mentioned before, the LoggingEventVO is intended for use by remote management tools, not for direct use by application code. The example is for demonstration purpose only.

You need to add logback classic library in the classpath to use this example
