Detailed Description

Generalisation of SimpleData, contains a vector of type_value_data values.

Used for indicators with multiple data, e.g., MACD, BOLL...
Once the object is created the size of the vector is fixed
It cannot be extended during the life time of the object (use of const nb_data as data member).

Member Function Documentation

void MultiData::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)

Implements DataStock.

Definition at line 562 of file DataStock.cpp.

References nb_data, SetData(), and Utils::StringToTime_t().

Here is the call graph for this function:

type_value_data MultiData::GetMaximum ( ) const

virtual

Get the maximum value.

Implements DataStock.

Definition at line 504 of file DataStock.cpp.

References values.

type_value_data MultiData::GetMinimum ( ) const

virtual

Get the minimum value.

Implements DataStock.

Definition at line 516 of file DataStock.cpp.

References values.

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

virtual

Return the value(s) in a vector.

Implements DataStock.

Definition at line 529 of file DataStock.cpp.

Referenced by HasChanged().

Here is the caller graph for this function:

bool MultiData::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 ?
