@ProviderType
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.

Caching information and settings can be found in portal.properties

findByLtSize

public static List<Image> findByLtSize(int size)
                                throws SystemException

Returns all the images where size < ?.

Parameters:

size - the size

Returns:

the matching images

Throws:

SystemException - if a system exception occurred

findByLtSize

public static List<Image> findByLtSize(int size,
                                       int start,
                                       int end)
                                throws SystemException

Returns a range of all the images where size < ?.

Useful when paginating results. Returns a maximum of end - start instances. start and end are not primary keys, they are indexes in the result set. Thus, 0 refers to the first result in the set. Setting both start and end to QueryUtil.ALL_POS will return the full result set. If orderByComparator is specified, then the query will include the given ORDER BY logic. If orderByComparator is absent and pagination is required (start and end are not QueryUtil.ALL_POS), then the query will include the default ORDER BY logic from ImageModelImpl. If both orderByComparator and pagination are absent, for performance reasons, the query will not have an ORDER BY clause and the returned result set will be sorted on by the primary key in an ascending order.

Parameters:

size - the size

start - the lower bound of the range of images

end - the upper bound of the range of images (not inclusive)

Returns:

the range of matching images

Throws:

SystemException - if a system exception occurred
