Member Function Documentation

void SimpleData::ExtractCSVLine ( std::vector< std::string > & linecsv )

virtual

Extract the data from a splitted string.

Format expected : "Date","float"

Parameters

linecsv line already split in a vector

Here is the caller graph for this function:

std::vector< type_value_data > SimpleData::GetValues ( ) const

virtual

Return the value(s) in a vector.

Implements DataStock.

Definition at line 306 of file DataStock.cpp.

References value.

bool SimpleData::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 ?
