如何知道typeSignature属性中的类型是否引用了扩展某个类的任何类？

import java.lang.reflect.*;

public class TypeSignatureAnalyzer {
    public static boolean isClassReferenced(String typeSignature, Class<?> superClass) throws ClassNotFoundException {
        // 获取类型的Class对象
        Class<?> type = Class.forName(typeSignature);

        // 分析字段类型
        Field[] fields = type.getDeclaredFields();
        for (Field field : fields) {
            if (field.getType().isAssignableFrom(superClass)) {
                return true;
            }
        }

        // 分析方法返回类型和参数类型
        Method[] methods = type.getDeclaredMethods();
        for (Method method : methods) {
            if (method.getReturnType().isAssignableFrom(superClass)) {
                return true;
            }
            for (Class<?> parameterType : method.getParameterTypes()) {
                if (parameterType.isAssignableFrom(superClass)) {
                    return true;
                }
            }
        }

        return false;
    }

    public static void main(String[] args) throws ClassNotFoundException {
        String typeSignature = "com.example.MyClass";
        Class<?> superClass = com.example.SuperClass.class;

        boolean isReferenced = isClassReferenced(typeSignature, superClass);
        if (isReferenced) {
            System.out.println("The type " + typeSignature + " references a class extending " + superClass.getName());
        } else {
            System.out.println("The type " + typeSignature + " does not reference a class extending " + superClass.getName());
        }
    }
}
