public class ImportAdapterCSV extends ImportAdapter
Import adapter for CSV files This adapter can import data from a CSV file. The CSV file itself is described by an appropriate ImportConfigurationCSV object. Internally this class makes use of CSVDataInput to read the CSV file on a line by line basis. A counting input stream (@link CountingInputStream} is used in order for Ungültige Eingabe: "to be able to return the percentage of data that has already been processed. @author Karol Babioch @author Fabian Prasser"
