Analyze the data. This counts the records and prepares the data to be processed.
public Analyze ( FileInfo inputFile, bool headers, CSVFormat format ) : void
inputFile System.IO.FileInfo The input file to process.
headers bool True, if headers are present.
format Encog.Util.CSV.CSVFormat The format of the CSV file.
Результат void
