Here is the call graph for this function:

void DataCSV::ExtractCSVLine ( std::vector< std::string > & vec )

virtual

Extract date and data from a split string.

Deprecated:: keep only for test performance comparison. Use operators<< >> now.

Parameters

vec	vector of string containing the date and the value(s)

virtual

Return the values in a vector, always 4 values: open, high, low, close.

Implements DataStock.

Definition at line 771 of file DataStock.cpp.

References close, high, low, and open.

bool DataCSV::HasChanged ( const DataStock & data_to_check ) const

virtual

Check if data are different.

To compare all fields use operator==
Exact implementation is different for each derived class:

DataCSV compare only close and date
SimpleData and MultiData compare all values

Todo:: check why DataCSV compares dates also, not the others why not use == now
case of double dispatching for DataCSV when compared with SimpleData, makes more general ?

Returns: true if values are considered different

Implements DataStock.
