Class CSVReader

  • All Implemented Interfaces:
    DataReader

    public class CSVReader
extends AbstractDataReader

    This class CSVReader implements default behavior of the DataReader interface. This class reads in the data source information from the configuration, loads the csv file data.

    This class is invoked by initDataReaderConfig method in BusinessObjectLoader individual methods:

    1. init();
    2. read();
    3. close();

    Before you call read(), you can call other methods to get and set additional properties if these properties are not defined in the configuration file or you want to override the value in the configuration file. To get and set configuration properties, you can call:

    • getConfigProperties().getPropertyMap();
    • setConfigProperties().getPropertyMap();
