主要分两种情况：存储的内容是指针；存储的内容是实际对象。
看下面两段代码，
typedef pair<VirObjTYPE, std::list<CheckID>*> VirObj_CheckID_pair;class LangChecker{public:LangChecker();~LangChecker();void Register(VirObjTYPE type, CheckID id);private:std::map<VirObjTYPE, std::list<CheckID>*> _registered_checker;std::map<VirObjTYPE, std::list<CheckID>*>::iterator _registered_iter;};
void LangChecker::Register(VirObjTYPE type, CheckID id){_registered_iter = _registered_checker.find(type);if(_registered_iter == _registered_checker.end()) //not found{std::list<CheckID>* newlist = new list<CheckID>;(*newlist).push_back(id);_registered_checker.insert(VirObj_CheckID_pair(type, newlist));}else{(*(*_registered_iter).second).push_back(id);}}LangChecker::~LangChecker(){for(_registered_iter = _registered_checker.begin();_registered_iter != _registered_checker.end(); _regeristered_iter++){delete (*_registered_iter).second;}}
std::map<VirObjTYPE, std::list<CheckID>> _registered_checker;std::map<VirObjTYPE, std::list<CheckID>>::iterator _registered_iter;
void LangChecker::Register(VirObjTYPE type, CheckID id){_registered_iter = _registered_checker.find(type);if(_registered_iter == _registered_checker.end()) //not found{std::list<CheckID>* newlist = new list<CheckID>;(*newlist).push_back(id);_registered_checker.insert(VirObj_CheckID_pair(type, *newlist));delete newlist;}else{(*_registered_iter).second.push_back(id);}}
