alljoyn PC端程序的模块化写法

加精

相信学习了alljoyn 官方的PC端例子代码之后，有童鞋会觉得官方代码没有按照模块化的方法来写，所有类、函数全部给整在了一个文件中。功能一旦复杂起来，就不好定位查找了。所以就尝试性地把alljoyn程序模块化，按照c++程序的封装思想，自定义三个类MyBusAttachment,MyBuslisterner,MyBusObject。具体的做法可以是这样：
MyBusAttachment.h

class ServiceBusAttachment:public BusAttachment

{

	

public:

	ServiceBusAttachment(const char* appname,bool f);



	void advertiseService(const TransportMask mask,MyBusListener& busListener);

	

	void createInterface();

	

private:

	

	void requestName();

	void advertiseName(TransportMask mask);

	void createSession(const TransportMask mask,MyBusListener& busListener);



};

MyBuslisterner.h

class MyBusListener : public BusListener, public SessionPortListener, public SessionListener

{

public:



	virtual bool AcceptSessionJoiner(SessionPort sessionPort, const char* joiner, const SessionOpts& opts);

	virtual void SessionJoined(SessionPort sessionPort, SessionId id, const char* joiner);

	virtual void NameOwnerChanged(const char* busName, const char* previousOwner, const char* newOwner);

};

MyBusObject.h

class MyBusObject : public BusObject

{

public:

	MyBusObject(BusAttachment& bus, const char* path);



	QStatus SendCmdSignal(const char* cmd);

	void ChatSignalHandler(const InterfaceDescription::Member* member, const char* srcPath, ajn::Message& msg);

	void Cat(const InterfaceDescription::Member* member,ajn::Message& msg);



private:

	const InterfaceDescription::Member* chatSignalMember;

	const InterfaceDescription::Member* commandSendedSignalMember;

};

以上三个文件只是个示例，然后在相应cc文件中定义各个方法即可。在主程序中，就可以这样写：

QStatus status = ER_OK;



	servicebus = new ServiceBusAttachment("myapp",true);

	servicebus->createInterface();

   	servicebus->RegisterBusListener(busListener);

    servicebus->Start();

    MyBusObject myobj(*servicebus, objPath);

    s_obj = &myobj;



    servicebus->RegisterBusObject(*s_obj);

    servicebus->Connect();



	const TransportMask SERVICE_TRANSPORT_TYPE = TRANSPORT_ANY;

	servicebus->advertiseService(SERVICE_TRANSPORT_TYPE,busListener);

这样的模块化安排是不是好多了呢？可以尝试把basic,chat等程序都写成这种形式哦。
