l
Each Record: These properties are evaluated and set at the beginning of each
source record. Once they have been set, these properties can be modified via an
Action step (see "Action step" on page258), but they are always reset at the
beginning of each source record.
l
Type: The data type of the property. For more information see "Data types" on page279.
l
Default Value: The initial value of the property. This is a JavaScript expression. See
"DataMapper Scripts API" on page372.
Note
Since Entire data properties are evaluated before anything else, such as
Preprocessors, Delimiters and Boundaries in the Settings pane (see "Data
source settings" on page222), these properties cannot read information from the
data sample or from any records.
Preprocessor
The Preprocessor subsection defines what preprocessor tasks are performed on the data file
before it is handed over to the data mapping workflow. Preprocessor tasks can modify the data
file in many ways, and each task runs in turn, using the result of the previous one as an input.
l
Name: The name to identify the Preprocessor task. Click this field to rename the
Preprocessor task.
l
Type: The type of Preprocessor task. Currently there is only one type available: script.
The buttons to the right can be used to add, remove and reorder the tasks and to apply them to
the current data file.
The Export button exports the current data file in its current state. Preprocessing may cost a lot
of time when the data file is very large. You could use the exported file instead of the original
file to avoid preprocessing while developing the workflow configuration.
Preprocessor definition
l
Expression: Enter the JavaScript code to be performed on the data file. See
"DataMapper Scripts API" on page372.
