public class ImageUtil
extends Object

The persistence utility for the image service. This utility wraps ImagePersistenceImpl and provides direct access to the database for CRUD operations. This utility should only be used by the service layer, as it must operate within a transaction. Never access this utility in a JSP, controller, model, or other front-end class.

Never modify this class directly. Modify service.xml and rerun ServiceBuilder to regenerate this class.

Caching information and settings can be found in portal.properties

ImagePersistence, ImagePersistenceImpl

ServiceBuilder generated this class. Modifications in this class will be overwritten the next time is generated.
