You can enable a reverse transformation
if it is supported and installed. Reverse transformations enable you to recover
changes to the model or recover changes to source code. This process is useful
when the model and code are developed concurrently.
This
option is only available when you create or edit a UML-to-Java transformation
configuration.
When you enable the reverse transformation
in a UML-to-Java transformation configuration,
specific tasks are available for you to specify how the transformation generates
output when you run the Java-to-UML, or reverse, transformation.
