Member Function Documentation

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

pure 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)

Implemented in DataCSV, MultiData, and SimpleData.

time_t DataStock::GetDate ( ) const

inline

Get the date data member.

Returns: date of the data

Definition at line 126 of file DataStock.h.

References date.

Here is the caller graph for this function:

std::string DataStock::GetDateString ( const bool bhours = true ) const

Return the date in a string format: "YEAR-MOnth-DAy HH:MM:SS" (2014-11-10 13::25::00)

by default only "YEAR-MOnth-DAy"

Parameters

bhours optional boolean, true will include "HH:MM:SS"

Returns: formatted string

Here is the caller graph for this function:

struct tm DataStock::GetDateTm ( ) const

Get a tm structure of the date.

It allows specifaclly to access week number

Todo:

to make in Utils but only when tests will be written

Returns: struct tm

Here is the caller graph for this function:

virtual type_value_data DataStock::GetMaximum ( ) const

pure virtual

Get the maximum value.

Implemented in DataCSV, MultiData, and SimpleData.

virtual type_value_data DataStock::GetMinimum ( ) const

pure virtual

Get the minimum value.

Implemented in DataCSV, MultiData, and SimpleData.

virtual std::vector<type_value_data> DataStock::GetValues ( ) const

pure virtual

Return the value(s) in a vector.

Implemented in DataCSV, MultiData, and SimpleData.

Referenced by MultiData::HasChanged(), ListObjectStock< T >::SetObjectStock(), PStockLine::SetObjectStock(), and CollectionObjectStock::SetObjectStock().

Here is the caller graph for this function:

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

pure 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 ?
