Template class

[simone pilozzi]

Hi all,

I am trying to add some functionality (like download from bloomberg) to the TimeSeries class of QL.

I created an abstract (and template class) class with a pure virtual method BlpDownload to create the timeseries <T> from blp.

The compiler always raises the error c2248:impossible d'accder private membre dclar(e) dans la class.

Here is part of the code (qDate is a typedef for QuantLib::Date)

 

the abstract class

template

<class T>

class timeseries{

timeseries(){}

inline

timeseries(const timeseries& original){

dates = original.getDates();

data = original.getData();

ts = original.getSeries();

}

inline vector<T>getData()const{return data;}

inline vector<qDate> getDates()const{return dates;}

virtual void blpDownload(string& assetname,vector<string> attributes,shared_ptr<Session> sessionptr)= 0;

protected

:

vector<qDate> dates;

vector<T> data;

TimeSeries<T>* ts;

};

 

the inherited class

class

financialtimeseries:public timeseries<vector<Real>>{

public:

financialtimeseries(){}

virtual void blpDownload(string& assetname,vector<string> attributes,

shared_ptr<Session> sessionptr);

};

void

financialtimeseries::blpDownload(string& assetname,

vector<string> attributes,shared_ptr<Session> sessionptr){.....blp download}

Any idea? Thanks in advance....

Found (thanks to Fabio), the abstract class misses the public keyword. I apologize for the stupid question
