com.liferay.expando.kernel.service.persistence.ExpandoRowUtil

public class ExpandoRowUtil
extends Object

The persistence utility for the expando row service. This utility wraps com.liferay.portlet.expando.service.persistence.impl.ExpandoRowPersistenceImpl 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

start - the lower bound of the range of expando rows

end - the upper bound of the range of expando rows (not inclusive)

Returns:

the range of matching expando rows

NoSuchRowException - if a expando row with the primary key could not be found

fetchByPrimaryKey

public static ExpandoRow fetchByPrimaryKey(long rowId)

Returns the expando row with the primary key or returns null if it could not be found.

Parameters:

rowId - the primary key of the expando row

the expando row, or null if a expando row with the primary key could not be found

findAll

public static List<ExpandoRow> findAll()

Returns all the expando rows.

Returns:

the expando rows

findAll

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

Returns a range of all the expando rows.

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, then the query will include the default ORDER BY logic from ExpandoRowModelImpl.

Parameters:

start - the lower bound of the range of expando rows

end - the upper bound of the range of expando rows (not inclusive)

Returns:

the range of expando rows

findAll

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

Returns an ordered range of all the expando rows.

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.

Parameters:

start - the lower bound of the range of expando rows

end - the upper bound of the range of expando rows (not inclusive)

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

Returns:

the ordered range of expando rows

                                       boolean useFinderCache)
