Dm create message new
本文讨论了新架构中消息的设计，包括消息类的实现和逻辑处理，以及 kdataobject 的操作。介绍了通过代理模式优化对 kdataobject 的查询、增删改操作和 XML 数据组装的方法。最后指出了在设计逻辑时，程序员需要负责逻辑分类与组织。
Dm create message new

- 4. 新架構的一支Message會這樣執行 (MessageId = ModuleName_MessageName)沒有Request/Reply的字 直接找MessageId.h/.cpp
- 5. MessageId.h #ifndef MessageId_H #define MessageId_H #include"...h" class ServiceKernel; class MessageId : public KMessageProcessorBase { public: MessageId(ServiceKernel* m_ServiceKernel, string m_ChannelId, string m_MessageId, KFabLinkMessageType m_MessageType, bool m_IsMonitor, KFabLinkTransaction& m_Transaction); //建構式 virtual void MessageLogic(); //執行Message的邏輯函數 }; #endif
- 6. MessageId.cpp 建構式 MessageId::MessageId (...): KMessageProcessorBase(m_ServiceKernel, m_ChannelId,m_MessageId, m_MessageType, m_IsMonitor, m_Transaction) { } 執行父類別中有 參數的建構式
- 7.
- 8. MessageId.cpp 執行Message的邏輯函數(非Query) void MessageId::MessageLogic() { KDoTransaction transaction;//KDo要加入交易才可以寫入資料庫 try{ //do any thing if (!transaction.Commit()){ throw FablinkException(ERROR_FABLINK_TRANSACTION_COMMIT_FALSE); } } catch (...){ transaction.Rollback(); throw; } } 捕捉到任何錯誤 都執行Rollback 並把錯誤再往外拋 若交易Commit出錯，拋出 ERROR_FABLINK_TRANSACTION_COMMIT_FALSE
- 9.
- 10. Visual Studio 2005的SolutionExplorer DMServer>ConstDefine SuMsgErrorCode.h/.cpp error code的宣告與定義(與新架構共用) DMServer>ConstDefine>FablinkKgs fKDataTime 特別為Fablink加強的KDataTime版本(與新架構共用) fSysUtils 特別為Fablink加強的SysUtils版本(與新架構共用)
- 11. Visual Studio 2005的SolutionExplorer DMServer>Impl>Others FablinkCriticalSection.h 會自動解鎖的CriticalSection FablinkException.h/.cpp 新架構執行出問題拋出exception的指定類型 FilePathConfig.h/.cpp config檔案的一切 KDoTransaction.h/.cpp 為了接近.dll檔的寫法重包一次的交易物件
- 12. Visual Studio 2005的SolutionExplorer DMServer>Impl>objMessage MainObj 代理資料表的類別, 通常名稱是TableName1.h/.cpp MsgObjs Message類別MessageId.h/.cpp (MessageId = ModuleName_MessageName) 沒有Request/Reply的字 KMessageProcessorBase.h/.cpp Message共用的Interface MessageProcessorFactory.h/.cpp Message的工廠模式 (用message id換message object的地方)

- 19. 先想想, 剛剛被畫掉的 • 查詢KDataObject •新增資料到KDataObject • 修改資料到KDataObject • 刪除KDataObject • 組KDataObject的Xml • 物件邏輯 (工序加報工機、機加到工作中心、報的項目要連動…)
- 20.
- 21. 所以應該是這樣？ class KDoOrganization :public KDataPersistentObject { public: //member value string Id; string Name; public: KDoEmployee* GetCoBoss(); void SetCoBoss( KDoEmployee* m_Object); public: //member function void DeleteAllWorkCenterEmpRelation(); void DeleteAllOrgEmpRelation(); EmployeeList1 GetEmployeesInOrganization() const; public: KXmlItem GetXml_OrganizationInfo(const string& m_InfoName) const; }
- 22.
- 23.
- 24. 借鏡Proxy Pattern obj->Id; //呼叫KDoObject的value(Id) obj->Function();//呼叫KDoObject的funciton obj.Function(); //呼叫TableObject1的funciton
- 25.
- 26. 就可以解決, 剛剛被畫掉的 • 查詢KDataObject •新增/修改/刪除KDataObject • 組KDataObject的Xml • 物件邏輯 (工序加報工機、機加到工作中心、報的項目要連動…)
- 27. 查詢KDataObject 查詢唯一值 class Organization1 :public KDoProxy1 { public: Organization1(const string& m_Id, unsigned int m_ActiveFlagType, KDoTransaction* const m_Transaction = 0); Organization1(const string& m_SystemKey, KDoTransaction* const m_Transaction = 0); Organization1(KDoTransaction* const m_Transaction = 0); Organization1(KDoOrganization* m_KDataObject, KDoTransaction* const m_Transaction = 0); //... } 其它常用查詢 class OrganizationList1 { public: OrganizationList1(const string& m_Id, unsigned int m_ActiveFlagType, KDoTransaction* const m_Transaction = 0); OrganizationList1(list<string>& m_IdList, unsigned int m_ActiveFlagType); OrganizationList1(list<string>& m_SystemKeyList, KDoTransaction* const m_Transaction = 0); OrganizationList1(const FilterType& m_FilterType, QueryByPaging1& m_Filter, KDoTransaction* const m_Transaction = 0); OrganizationList1(unsigned int m_ActiveFlagType); OrganizationList1(list<KDoOrganization*>& m_List); //… }
- 28. 新增/修改/刪除KDataObject class Organization1 :public KDoProxy1 { public: void CreateToTable(KXmlItem& m_XmlInfo); void ModifyToTable(KXmlItem& m_XmlInfo); void ModifyToDelete(); //... } class OrganizationList1 { public: void DeleteList(); //… }
- 29. 組KDataObject的Xml class Organization1 :public KDoProxy1 { private: KXmlItem GetXml_Leader3() const; KXmlItem GetXml_Leader6() const; public: KXmlItem GetXml_OrganizationInfo(const string& m_InfoName = "OrganizationInfo") const; KXmlItem GetXml_OrgInfo_Leader3(const string& m_InfoName = "OrgInfo") const; KXmlItem GetXml_OrgInfo_Leader6(const string& m_InfoName = "OrgInfo") const; //... } class OrganizationList1 { public: KXmlItem GetXml_OrganizationList(const string& m_ListName, const string& m_InfoName) const; KXmlItem GetXml_OrgList_v1(const string& m_ListName, const string& m_InfoName) const; //… }
- 30. 物件邏輯 class Organization1 :public KDoProxy1 { public: void DeleteAllWorkCenterEmpRelation(); void DeleteAllOrgEmpRelation(); EmployeeList1 GetEmployeesInOrganization() const; //... } class OrganizationList1 { public: const unsigned int& Size() const; bool In( const Organization1& m_Obj ) const; //… }
