ice Callback

一 接口描述，本例子定义了两个接口

    接口 CallbackSender 中的方法 void initiateCallback(CallbackReceiver* proxy);用于向服务器传递Proxy

    接口 CallbackReceiver 中的方法 void callback(); 用于服务器的回调

三 实现接口

CallbackSenderI.h

这个接口被 Server 实现,客户端调用这个接口，服务端执行，将Proxy CallbackReceiverPrx 传递到服务器

// **********************************************************************//// Copyright (c) 2003-2016 ZeroC, Inc. All rights reserved.//// **********************************************************************#ifndef CALLBACK_I_H#define CALLBACK_I_H#include <Callback.h>class CallbackSenderI : public Demo::CallbackSender{public:    virtual void initiateCallback(const Demo::CallbackReceiverPrx&, const Ice::Current&);    virtual void shutdown(const Ice::Current&);};#endif

CallbackSenderI.cpp

从这可以看出，代理是可以在通信的双方互相传递的

// **********************************************************************//// Copyright (c) 2003-2016 ZeroC, Inc. All rights reserved.//// **********************************************************************#include <Ice/Ice.h>#include <CallbackSenderI.h>using namespace std;using namespace Ice;using namespace Demo;voidCallbackSenderI::initiateCallback(const CallbackReceiverPrx& proxy, const Current&){    cout << "initiating callback" << endl;    try    {        proxy->callback();    }    catch(const Exception& ex)    {        cout << ex << endl;    }}voidCallbackSenderI::shutdown(const Current& c){    cout << "shutting down..." << endl;    try    {        c.adapter->getCommunicator()->shutdown();    }    catch(const Exception& ex)    {        cout << ex << endl;    }}

四 客户端与服务器

客户端说明：

1)  代理对象是由通信器创建的 ,使用了配置文件中的 CallbackSender.Proxy=callbackSender:default -h localhost -p 10000

2)  适配器对象由通信器创建, 使用了配置文件 中的 Callback.Client.Endpoints=default -h localhost

3) 回调的实现，其实就是 服务端的适配器+servant的模式 在客户端的实现。使用也只需要这几步

    a) 生成适配器  (通信器+配置文件)

         Ice::ObjectAdapterPtr adapter = communicator()->createObjectAdapter("Callback.Client");

   b) 创建servant

        CallbackReceiverPtr cr = new CallbackReceiverI;

  c) 将servant 加入适配器 并激活\

      adapter->add(cr, communicator()->stringToIdentity("callbackReceiver"));
      adapter->activate();

4) 传递代理给服务器

   a) 创建要传递的代理，注意这次创建代理与前面创建不同，这次由适配器创建，而不是由通信器创建

       CallbackReceiverPrx receiver = adapter->createProxy(communicator()->stringToIdentity("callbackReceiver"))

   b) 传递给服务器

        sender->initiateCallback(receiver);

 创建适配器：通信器+配置文件

 创建servant

 将servant加入适配器并激活
