Implementing Custom Behavior for Your Classes
The user interface you designed in Interface Builder already allows you to insert and delete Studio objects. However, it doesn't do any additional processing when these operations take place. For example, what if you want to assign default values to newly created objects? And how can you prevent users from inserting objects that contain invalid data? You can add methods to your enterprise objects to handle such issues. Related Concepts: Adding Behavior to Enterprise ObjectsDistributing Business Logic in Java Client Applications
