reference data class member visitor pattern

I have a container class that has a plain old datatype called DataStore. This data store will be passed to visitor.They share a single copy since any updated performed by the container are to be seen by visitor.

class xyz
{
    //Plain Old Datatype
    typedef struct DataStore
    {
        //add any new required data by any test here
        bool    _detectorConnectionStatus;
        DataStore():_detectorConnectionStatus(false){}
    }DataStore;

    DataStore _dataStore;

    typedef struct visitorData
    {
        DataStore& dataStore;
        visitorData(DataStore data):dataStore(data){}
    }visitorData;

    //data to be sent to visitor
    visitorData _visitorData;
};

xyz::xyz():_visitorData(_dataStore)
{
}

class IVisitor
{
private:
struct DataStore* dataStore;
public:
//get the data,no check for validity of data performed
 void visit(struct DataStore& dataStore){};
//process the data
virtual void process() = 0;
};

The code compiles but is there a better/cleaner way to do it?
