使用 JNA 访问包含多个类的 DLL 方法

我是使用 JNA 从 Java 访问 DLL 的新手，所以如果这对每个人来说都是显而易见的，请原谅我！我需要从 DLL 中的类（用 VB 编写）访问方法，并且不能通过仅加载库来做到这一点，因为我看到如何访问其中的类，即 DLL 称为 CDrawControl.dll，但其中的类我需要访问的DLL是DrawCtl。所以我需要获取 DrawCtl 类的实例。总而言之，如何使用 JNA 访问 DLL 中的这个方法？

即 CDrawControl.DrawCtl.SaveFile()

这可能是我所缺少的非常简单的东西。

public class ReadDLL {
    public interface ChemDrawCtl12 extends Library {
    CDrawControl INSTANCE = (CDrawControl) Native.loadLibrary(
            (Platform.isWindows() ? "CDrawControl" : "CDrawCtl12LinuxPort"),
            CDrawControl.class);

    void DrawCtl.SaveAs(); // this is wrong but shows what I am trying to do!!
}

I am new to accessing DLLs from Java using JNA,so forgive me if this is obvious to everyone! I need to access methods from a class within a DLL(which was written in VB) and cannot do this by just loading the library as I see how to access a class within it I.e. the DLL is called CDrawControl.dll, but the class within the DLL I need to access is DrawCtl. So I need to get an instance of the DrawCtl class.
So all in all, how to I reach this method in the DLL using JNA?

I.e. CDrawControl.DrawCtl.SaveFile()

It is probably something very simple I am missing.

public class ReadDLL {
    public interface ChemDrawCtl12 extends Library {
    CDrawControl INSTANCE = (CDrawControl) Native.loadLibrary(
            (Platform.isWindows() ? "CDrawControl" : "CDrawCtl12LinuxPort"),
            CDrawControl.class);

    void DrawCtl.SaveAs(); // this is wrong but shows what I am trying to do!!
}
