向函数传递stl::vector迭代器项

我有以下定义:

typedef struct tagDemoEntryAssign
{
    COleDateTime datMeeting;
    CString      strAssignment;
    int          iAssignmentType; // AJT v16.0.9
    int          iStudyPoint;     // AJT v16.0.3
    int          iNextStudyPoint; // AJT v16.0.9
} S_DEMO_ENTRY_ASSIGN;

using PublisherAssignments = std::vector<S_DEMO_ENTRY_ASSIGN>;

typedef struct tagDemoEntryEx
{
    CString     strName;
    E_GENDER    eGender;
    E_POSITION  ePosition;
    E_APPOINTED eAppointed;
    BOOL        bDemonstrations; // AJT v16.0.3

    PublisherAssignments  vectorItemAssign;       // Sorted array of S_DEMO_ENTRY_ASSIGN structures.
    PublisherAssignments  vectorItemAssignFuture; // Sorted array of S_DEMO_ENTRY_ASSIGN structures (future on active schedule).
} S_DEMO_ENTRY_EX;

using PublisherMap = std::map<CString, S_DEMO_ENTRY_EX>;
using PublisherMapIter = std::map<CString, S_DEMO_ENTRY_EX>::iterator;

我有这张地图:

PublisherMap m_mapPublishers;

我正在反向迭代发布者的工作分配:

for (auto & m_mapPublisher : m_mapPublishers)
{
    for (auto iterAssign = m_mapPublisher.second.vectorItemAssign.rbegin();
        iterAssign != m_mapPublisher.second.vectorItemAssign.rend(); iterAssign++)
    {
        S_DEMO_ENTRY_ASSIGN sDemoEntryAssign = *iterAssign;
        bool bValidAssignment = GetMostRecentDateForAssignment(m_eAssignmentContext, sDemoEntryAssign);
        // ...
    }
}

以前我只是用 iterAssign-> 访问结构值,但我决定移动内部代码 for 循环到方法中。我唯一能想到的方法就是通过这个结构 iterAssign 方法是先复制它。

还有其他方法可以将vectore迭代器条目传递到函数中吗?
