Java transformation fields

Java transformation fields

A Java transformation has incoming fields and output fields. Use incoming and output fields as variables in the Java code snippets that you define on the
Java
tab.
Incoming fields appear on the
Incoming Fields
tab. By default, the Java transformation inherits all incoming fields from the upstream transformation. If you do not need to use all of the incoming fields, you can define field rules to include or exclude certain fields. For more information about field rules, see Field rules.
Add output fields on the
Output Fields
tab. Add output fields for the output data that you want to pass to the downstream transformation. To add a field, click
Add Field
, and then enter the field name, data type, precision, scale, and optional description. The description can contain up to 4000 characters. You can also create output fields on the
Outputs
tab of the Java editor by clicking
Create New Field
.
The Java transformation initializes output field values based on the following field data types:
  • Primitive data types. The transformation initializes the value of the field variable to 0.
  • Complex data types. The transformation initializes the field variable to null.
