初始化对象不在控制器中但在自己的类中 - 是否是任何模式？

Question

有时我必须在将模型传递给视图之前填充模型。我可以在控制器中的动作中执行此操作：

public class FormController
{
    public ActionResult Index(int recruitmentId, int employerId)
    {
        EmploymentForm employmentForm = new EmploymentForm();
        employmentForm.StartDate = new DateTime();
        employmentForm.RecruitmentId = recruitmentId;
        employmentForm.EmployerId = employerId;
        // much more properties with some logic (for example connect to database to fill them)

        return View(employmentForm);
    }
}

但是动作很长，所以我创建了自己的类，然后在那里填写模型：

public class EmploymentFormInitializator
{
    private int _recruitmentId;
    private int _employerId;
    public EmploymentFormInitializator(int recruitmentId, int employerId)
    {
        _recruitmentId = recruitmentId;
        _employerId = employerId;
    }

    public EmploymentForm Init()
    {
        EmploymentForm employmentForm = new EmploymentForm();
        employmentForm.StartDate = new DateTime();
        employmentForm.RecruitmentId = _recruitmentId;
        employmentForm.EmployerId = _employerId;
        // much more properties with some logic (for example connect to database to fill them)

        return employmentForm;
    }
}

然后我的控制器很短：

public class FormController
{
    public ActionResult Index(int recruitmentId, int employerId)
    {
        EmploymentFormInitializator employmentFormInitializator = new EmploymentFormInitializator(recruitmentId, employerId);
        EmploymentForm employmentForm = employmentFormInitializator.Init();

        return View(employmentForm);
    }
}

在这种情况下我使用什么模式？ EmploymentFormInitializator类可能是工厂，构建器还是可能不是任何模式？
