The logback.classic.model.ReceiverModelHandler class is used to handle the receiver elements in the logback configuration file. It is responsible for creating ReceiverModel instances based on the configuration and the Receiver instances. Here is an example of how you might use the ReceiverModelHandler class in a Java application:

import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.classic.joran.JoranConfigurator;
import ch.qos.logback.classic.model.ReceiverModel;
import ch.qos.logback.classic.model.ReceiverModelHandler;
import ch.qos.logback.core.joran.spi.JoranException;
import ch.qos.logback.core.util.StatusPrinter;

public class MyApplication {
  public static void main(String[] args) {
    LoggerContext loggerContext = new LoggerContext();
    JoranConfigurator configurator = new JoranConfigurator();
    configurator.setContext(loggerContext);
    ReceiverModelHandler receiverModelHandler = new ReceiverModelHandler(loggerContext);
    configurator.addRuleStore(receiverModelHandler);
    try {
        configurator.doConfigure(pathToLogbackXML);
    } catch (JoranException e) {
        e.printStackTrace();
    }
    StatusPrinter.printInCaseOfErrorsOrWarnings(loggerContext);
  }
}

In this example, a LoggerContext and JoranConfigurator are created, and ReceiverModelHandler is added to the configurator's rule store via configurator.addRuleStore(receiverModelHandler). So, when it encounters a element in the configuration file, the ReceiverModelHandler will be responsible for creating a ReceiverModel instance, it will parse the configuration and call the configure() method of that receiver on the context.

It's worth noting that this is just a sample, you need to have a logback.xml or logback-test.xml file in your classpath or configure it manually. And in your logback configuration file you need to have a element properly configured to use this example. Also ReceiverModel class allows you to configure different receivers, based on your requirement you can use them with different options.
