This use case shows that it is possible to access the input flow using a dedicated variable and following a specific syntax such as: input_row.name. The source data is processed at runtime by the tJavaRow component.

A common Job using tJavaRow is generally composed of:

  • a tFileInputDelimited component to read data from a text file,
  • a tJavaRow to apply transformation to the data processed,
  • a tLogRow component to print data in the console.

Procedure

  1. In the Palette, slide a tFileInputDelimited , a tJavaRow and a tLogRow component onto the workspace.
  2. Connect tFileInputDelimited to tJavaRow and tJavaRow to tLogRow using a Row > Main link.
  3. Set the Basic settings of the tFileInputDelimited component.
  4. Double-click on tFileInputDelimited to display its Basic settings. The tFileInputDelimited reads the same text file and use the same schema as in the tJava example .
  5. When prompted, click OK to accept the propagation or click afterward on the Sync columns button in the Basic settings view of tJavaRow.
  6. Double-click on tJavaRow to display its Basic settings view and add the following code in the Code area: 
    output_row.id = input_row.id;
output_row.name = (input_row.name).toUpperCase();
    Note: This code converts the column names to upper case.
  7. Execute the Job by pressing F6.
