Method Detail

calculate

public double calculate(Series sourceSeries,
                        int firstIndex,
                        int lastIndex)

Performs function operation on SourceSeries series.
First and Last parameters are ValueIndex of first and last point used in calculation.
You can override Calculate function to perform customized calculation on one SourceSeries.

Overrides:

calculate in class Function

Parameters:

sourceSeries - Series

firstIndex - int

lastIndex - int

Returns:

double

calculateMany

public double calculateMany(java.util.ArrayList sourceSeriesList,
                            int valueIndex)

Performs function operation on list of series (SourceSeriesList).
The ValueIndex parameter defines ValueIndex of point in each Series in list. You can override CalculateMany function to perform customized calculation on list of SourceSeries.

Overrides:

calculateMany in class Function

Parameters:

sourceSeriesList - ArrayList

valueIndex - int

Returns:

double

getDescription

public java.lang.String getDescription()

Gets descriptive text.

Overrides:

getDescription in class Function

Returns:

String
