Method Detail

convert

public double[] convert(RowData data,
                        double[] rawData)
                 throws PredictException

Parameters:

data - instance of RowData we want to get prediction for

rawData - array that will be filled up from RowData instance and returned

Returns:

`rawData` array with data from RowData.

Throws:

PredictException - Note: name of the exception feels like out of scope of the class with name `RowToRawDataConverter` but this conversion is only needed to make it possible to produce predictions so it makes sense
