Here is an example of how the ContextBase class from the logback library can be used:

import ch.qos.logback.classic.Logger;
import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.core.util.StatusPrinter;

public class MyClass {
    public static void main(String[] args) {
        LoggerContext loggerContext = new LoggerContext();
        loggerContext.setName("myLoggerContext");
        Logger logger = loggerContext.getLogger(MyClass.class);
        logger.debug("This is a debug message");
        logger.info("This is an info message");
        StatusPrinter.print(loggerContext);
    }
}

In this example, MyClass uses an instance of ContextBase to create a LoggerContext and set its name to "myLoggerContext". The LoggerContext is then used to obtain a Logger object for the MyClass class. The debug and info methods are used to log messages at different levels. Finally, StatusPrinter is used to print the status messages generated by the LoggerContext.

You can also use getName to get the name of the context.

String name = loggerContext.getName();

Here is an example of how you might use the ContextBase class from the logback library in Java:

import ch.qos.logback.core.ContextBase;

public class MyClass {
    public static void main(String[] args) {
        ContextBase context = new ContextBase();
        context.putProperty("applicationName", "MyApp");
        // ... additional configuration here ...
        // use the context in a logger
    }
}

In this example, we create a new instance of ContextBase, which is a basic implementation of the Context interface. We then use the putProperty method to set a property named "applicationName" with the value "MyApp". This context can then be used by a logger to configure itself.
