tFileInputRaw Standard properties

Schema and Edit Schema

A schema is a row description, it defines the number of fields to be processed and passed on to the next component. The schema is either Built-in or stored remotely in the Repository.

Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

• View schema: choose this option to view the schema only.

• Change to built-in property: choose this option to change the schema to Built-in for local changes.

• Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion.

  If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the Repository Content window.

Built-in: No property data stored centrally.

Repository: Select the repository file where the properties are stored. The fields that follow are completed automatically using the data retrieved.

Filename

The name of and path of the input file to be processed, which you can enter manually between double quotes or browse and select by clicking the [...] button.

Mode

Read the file as a string: The content of the file is read as a string.

Read the file as a bytes array: The content of the file is read as a bytes array.

Stream the file: As soon as the first character is entered in the source file, it is read immediately.

Encoding

If you are using the Read the file as a string mode, select the encoding type from the list or select Custom and define it manually.

Die on error

Select this check box to stop the execution of the Job when an error occurs. Clear the check box to skip the row on error and complete the process for error-free rows. If needed, you can collect the rows on error using a Row > Reject link.

To catch the FileNotFoundException, you also need to select this check box.

tStatCatcher Statistics

Select this check box to gather the processing metadata at the Job level as well as at each component level.

Global Variables

FILENAME_PATH: the path of the input file. This is an After variable and it returns a string.

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl+Space to access the variable list and choose the variable to use from it.
