DataSourceCsv

Overview

DataSourceCsv is a specialized DataSource for importing data from CSV files. This class is used to manipulate existing DataSourceCsv objects. To create a new DataSource use TFORMer Designer or Project.addDataSource.

The main properties to characterize a DataSourceCsv are:

• The filename
• The separator character
  This is usually a comma , and separates the single column names (= the names of the DataFields) and column values (= values of DataFields) from each other
• The qualifier character
  The qualifier character encloses column-values (e.g. "This is a string").
• Has column names
  Specifies if the CSV file contains the DataField names in the first line. If no names are provided TFORMer assumes the names Field_0, Field_1, etc.

Modifying an Existing CSV-DataSource

  // Retrieve the global Project
  // DataSources are defined in a Project or a global Project
  Project project = repository.getGlobalProject ();

  // Retrieve the DataSource by name
  // Since we know the type of the DataSource, we can cast it to DataSourceCsv
  DataSourceCsv dataSource = (DataSourceCsv)project.getDataSource("CSV");

  // Modify some DataSource properties  
  dataSource.setQualifier("'");
  dataSource.setSeparator(",");
