有没有办法通过编程来确定JMeter是否在“功能测试模式”下运行？

import org.apache.jmeter.JMeter;
import org.apache.jmeter.util.JMeterUtils;

public class JMeterModeCheck {
    public static void main(String[] args) {
        JMeterUtils.loadJMeterProperties("jmeter.properties");
        JMeterUtils.initLocale();

        boolean isFunctionalMode = JMeter.isFunctionalMode();

        if (isFunctionalMode) {
            System.out.println("JMeter is running in functional mode");
        } else {
            System.out.println("JMeter is not running in functional mode");
        }
    }
}
