Class ClusterGroupUtil

java.lang.Object
  extended by 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

                                            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:

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

the ordered range of cluster groups
Throws:
