任务编写一个XML一个请求类Request一个反应类.doc

1、一、任务：编写一个 XML, 个请求类(Request), 一个反应类(Response)。使Request能提取XML的信息，Response能用返回并显示提取的信息。并编写一个测试来验证程 序可以实现需要实现的函数。最后，附上说明文档。二、说明：1. Request 类概述：一个储存被解析过的 XML的类(parsed xml request)，可以利用 Request向Service类 发出请求，使 Service 能提取各种信息需要实现的函数 ：/ 提取各种信息的函数void Service:getGeneralInfo( Request & request,string & serv

2、iceType,PType & type,string & date,string & name,double & amount)/get type,e.g Astring reqType;if( request.isTypeSet( ) )reqType = request.getType( );if( reqType = A )type = A;if( reqType = B )type = B;if( reqType = C )type = C;if( serviceType = pClient ) / obtain information in pClient node of xml

3、requestProject pClient;if( request.isProjectSet( ) )pClient = request.getProject( );if( pClient.isAmountSet( ) )amount = pClient.getAmount( );if( pClient.isDateSet( ) )date = pClient.getDate( );if( pClient.isNameSet( ) )name = pClient.getName( );elsename = N.A,;2. Response 类概述：是一个Response Object,为Se

4、rive类显示相应信息需要实现的函数：/function to invoke servicevoid Service:solve( Request & request, Response & response )stringstype;problemType pType;stringdate;stringname;doubleamountgetGeneralInfo( request, stype, pType, date,name, amount );/first check if service type involved is pClientif( stype = pClient )sw

5、itch( pType )case A: createMyResponse( response ); break;case B: createYourResponse( response ); break;case C:createHisResponse( response ); break;default:err Ptype invalid ; error( err.str( ) ); break;/ creates response to My problem typevoid Service:createMyResponse(Response & response) MyClass my

6、Class; vector myFinal; myClass.setName(My); myClass.setType(My); myClass.setDate (20091001); myFinal.push_back(myClass);MyVector myVector; myVector.setMyVec(myFinal);MyResponse mResponse; mResponse.setMyFinal(myVector); response.setMyResponse(mResponse);/ creates response to Your problem typevoid Se

7、rvice:createYourResponse(Response &response) YourClass yourClass; vector yourFinal; yourClass.setName(Yours); yourClass.setType(Yours); yourClass.setDate (20090411); yourFinal.push_back(yourClass);YourVector yourVector; yourVector.setYourVec(yourFinal);yourResponse yResponse;yResponse.setYourFinal(y

8、ourVector); response.setYourResponse(yResponse);void Service:createHisResponse(Response &response)HisClass hisClass; vector hisFinal; hisClass.setName(His); hisClass.setType(His); hisClass.setDate(20080911); hisFinal.push_back(hisClass);HisVector hisVector; hisVector.setHisVec(hisFinal);HisReponse hResponse; hResponse.setHisFinal(hisVector); response.setHisResponse(hResponse);三、任
