Synchronizing Model Changes to Class Files

In the course of building an Enterprise Objects application, you’ll likely make changes to a model that affect enterprise object class files that you’ve generated from EOModeler, as described in “Generating Source Files.” Since you usually add custom logic to those enterprise object class files, you must make sure not to overwrite those changes when generating class files from an updated EOModel. EOModeler is careful to not blindly overwrite generated class files and instead presents a dialog allowing you to merge changes.

Clicking Merge in this dialog opens the FileMerge application and allows you to merge the updated entity definition class with the old entity definition class that contains custom business logic.
