GPG2권 1.6동적인형 정보 김준섭 (트라시르)
동적 형 정보 클래스 Dynamic Type Information
동적 형 정보 클래스 ? 실행시점에서 형에 대한 관리를 효율적으로 수행하기 위한 클래스
간단한 형태로 구현한 동적 형 정보 클래스 Class dtiClass { Private: char* szName; dtiClass* pdtiParent; Public: dtiClass(); dtiClass( char* szSetName, dtiClass* pSetParent ); virtual ditClass(); const char* GetName(); boolSetName( char* szSetName ); dtiClass* GetParent(); boolSetParent( dtiClass* pSetParent ); };
DTI 클래스 사용 Dynamic Type Information
DTI를 도입하려면 클래스들이 dtiClass를 static 맴버로포함을시키고 초기화 해야 한다. #define EXPOSE_TYPE br />	public: br />		static dtiClass Type; class CRootClass { public: EXPOSE_TYPE; CRootClass() {}; 	virtual ~CRootClass() {}; }; dtiClassCRootClass::Type( "CRootClass", NULL );
객체의 클래스 이름을 조회 pSomeptr->Type.GetName(); 객체의 부모 클래스 이름을 조회 pSomeptr->Type.GetParent()->GetName();
문제점 void main(void) { A* a = new B; cout << a->Type.GetName() << endl; cout<< *a->Type.GetName() << endl; } 출력 화면 A A
해결책 public:  static dtiClassType; public:	 	virtual dtiClass* RuntimeInfo() { return & Type; } 사용 void main(void) { A* a = new B; cout << a->Type.GetName() << endl; cout << a->RuntimeInfo()->GetName() << endl; } 출력 화면 A B
상속 관계 사용
다양한 종류의 객체들을 다형성을 사용하는 경우가 많다. 객체를 다른 것으로 형 변형하기 전에  그 객체가 호환 가능한 형인지를 확인해야 한다. booldtiClass::IsA( dtiClass* pType ) { dtiClass* pStartType = this; 	while( pStartType ) 	{ 		if ( pStartType == pType ) 		{ 			return true; 		} 		else 		{ pStartType = pStartType->GetParent(); 		} 	} 	return false; }
IsA함수를 이용하여 안전한 형변형을 위한 함수를 만들 수 있다. void* CRootClass::SafeCast( dtiClass* pCastToType ) { if ( Type.IsA( pCastToType ) ) { 		return this; } 	else { return NULL; } } 형 변형이 안전하지 않다면 NULL을 돌려준다.
영속적 형 정보 구현 Persistent Type information
객체에 대한 정보를 영속적으로 보관하거나 다시 들여오는 방법을 살펴보자 데이터를 저장하는 클래스를 만들고  파일에 읽거나 쓰기를 위한 Stream 맴버 함수와  		friend << 연산자를 정의해준다 friend CdtiBin& operator<<( CdtiBin& bin, int& data ) { bin.Stream( &data, sizeof(int) ); 	return bin; } 클래스가 저장 클래스와 연동할 수 있는 함수를 만들어준다. void CChildClass::Serialize( CdtiBin& ObjStore ) { Root::Serialize( ObjStore ); ObjStore << fMemberFloat << iAnotherInt; }
