JNative 如何传递复杂参数

[西木凌萧]

有个关于参数传递的问题
我该怎么往n = new JNative("rfid.dll","RFID_RetrieveAttachedRadiosList");
的 n中传递对需要的对象？？

 
//***key code:
/**  dll 里函数参数类型为

RFID_STATUS RFID_Startup(
RFID_VERSION*  pLibraryVersion,  
	INT32U   		 flags 
) 
RFID_VERSION 的类型为
typedef struct {  
INT32U  major;  
INT32U  minor;  
INT32U  maintenance;  
INT32U  release; 
 } RFID_VERSION; 


*/
//关键代码如下
n = new JNative("rfid.dll","RFID_Startup");
   //2.设置函数返回值类型
   n.setRetVal(Type.INT);
   //3.设置参数类型
   int i=0;
   RFID_VERSION rv = new RFID_VERSION();//参数类 下面已经给出
   n.setParameter(0, rv.getPointer());
   //执行函数
   n.invoke();
   //打印参数类的返回值
  System.out.println(rv.getValueFromPointer());
   
   //4.执行函数
   n.invoke();
   //5.获取函数返回值
  // System.out.print("正确返回");
 System.out.println(R.getValueFromPointer());
/* 打印如下：
    RFID_VERSION [major=2, minor=4, maintenance=2, release=240]
*/
   return n.getRetVal(); // 返回0：正常。
/*
  返回正常结果
*/

//RFID_VERSION  的代码如下

public class RFID_VERSION extends AbstractBasicData<RFID_VERSION> {

	
	public int major;
	public int minor;
	public int maintenance;
	public int release;
	public RFID_VERSION() throws NativeException {
        super(null);
        createPointer();
        mValue = this;
	}
	@Override
	public Pointer createPointer() throws NativeException {
		 pointer = new Pointer(MemoryBlockFactory.createMemoryBlock(getSizeOf()));
         return pointer;

	}
	@Override
	public int getSizeOf() {
		// TODO 自动生成的方法存根
		return 4*8;
	}
	@Override
	public RFID_VERSION getValueFromPointer() throws NativeException {

		major = getNextInt();
		minor = getNextInt();
		maintenance  =getNextInt();
		release  =getNextInt();
		return this;
	}
	@Override
	public String toString() {
		return "RFID_VERSION [major=" + major + ", minor=" + minor
				+ ", maintenance=" + maintenance + ", release=" + release + "]";
	}

}

//以上代码正确执行，现dll 有一个方法
RFID_STATUS RFID_RetrieveAttachedRadiosList(
	RFID_RADIO_ENUM*   	pBuffer,   
	INT32U      			flags ）
/*
参数为
typedef struct {  
    INT32U       		 length;  
    INT32U       		 totalLength;  
    INT32U       		 countRadios;  
    RFID_RADIO_INFO**  ppRadioInfo;  
} RFID_RADIO_ENUM; 


struct {  
    INT32U      	length;  
    RFID_VERSION  driverVersion;  //上面已经定义过
    INT32U      	cookie;  
    INT32U      	idLength;  
    INT8U*      	pUniqueId;  
} RFID_RADIO_INFO;
