Class ClusterGroupUtil

  com.liferay.portal.service.persistence.ClusterGroupUtil

@ProviderType
public class ClusterGroupUtil
extends Object

The persistence utility for the cluster group service. This utility wraps ClusterGroupPersistenceImpl 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

cacheResult

public static void cacheResult(List<ClusterGroup> clusterGroups)

Caches the cluster groups in the entity cache if it is enabled.

Parameters:

Removes the cluster group with the primary key from the database. Also notifies the appropriate model listeners.

Parameters:

clusterGroupId - the primary key of the cluster group

Returns:

the cluster group that was removed

Throws:

NoSuchClusterGroupException - if a cluster group with the primary key could not be found

SystemException - if a system exception occurred

updateImpl

                                     throws NoSuchClusterGroupException,
                                            SystemException

Returns the cluster group with the primary key or throws a NoSuchClusterGroupException if it could not be found.

Parameters:

clusterGroupId - the primary key of the cluster group

Returns:

the cluster group

Throws:

NoSuchClusterGroupException - if a cluster group with the primary key could not be found

SystemException - if a system exception occurred

fetchByPrimaryKey

public static ClusterGroup fetchByPrimaryKey(long clusterGroupId)
                                      throws SystemException

Returns the cluster group with the primary key or returns null if it could not be found.

Parameters:

clusterGroupId - the primary key of the cluster group

Returns:

the cluster group, or null if a cluster group with the primary key could not be found

Throws:

SystemException - if a system exception occurred

findAll

public static List<ClusterGroup> findAll()
                                  throws SystemException

Returns all the cluster groups.

Returns:

the cluster groups

Throws:

SystemException - if a system exception occurred

findAll

public static List<ClusterGroup> findAll(int start,
                                         int end)
                                  throws SystemException

Returns a range of all the cluster groups.

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 ClusterGroupModelImpl. 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 cluster groups

end - the upper bound of the range of cluster groups (not inclusive)

Returns:

the range of cluster groups

Throws:

SystemException - if a system exception occurred

findAll

public static List<ClusterGroup> findAll(int start,
                                         int end,
                                         OrderByComparator orderByComparator)
                                  throws SystemException

Returns an ordered range of all the cluster groups.

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 cluster groups

end - the upper bound of the range of cluster groups (not inclusive)

the ordered range of cluster groups
