com.liferay.portal.kernel.service.persistence.ClassNameUtil

@ProviderType
public class ClassNameUtil
extends Object

The persistence utility for the class name service. This utility wraps ClassNamePersistenceImpl 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

fetchByPrimaryKeys

findAll

public static List<ClassName> findAll()

Returns all the class names.

Returns:

the class names

findAll

public static List<ClassName> findAll(int start,
                                      int end)

Returns a range of all the class names.

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 ClassNameModelImpl. 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:

start - the lower bound of the range of class names

end - the upper bound of the range of class names (not inclusive)

Returns:

the range of class names

findAll

public static List<ClassName> findAll(int start,
                                      int end,
                                      OrderByComparator<ClassName> orderByComparator)

Returns an ordered range of all the class names.

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 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:

start - the lower bound of the range of class names

end - the upper bound of the range of class names (not inclusive)

orderByComparator - the comparator to order the results by (optionally null)

Returns:

the ordered range of class names

findAll

                                      boolean retrieveFromCache)
