clearCache

void clearCache(List<T> modelList)

Clears the cache for a List instances of this model.

The EntityCache and FinderCache are both cleared by this method.

Parameters:

modelList - the List instances of this model to clear the cache for

clearCache

void clearCache(T model)

Clears the cache for one instance of this model.

The EntityCache and FinderCache are both cleared by this method.

Parameters:

model - the instance of this model to clear the cache for

closeSession

void closeSession(Session session)

countWithDynamicQuery

long countWithDynamicQuery(DynamicQuery dynamicQuery)

Returns the number of rows that match the dynamic query.

Parameters:

dynamicQuery - the dynamic query

Returns:

the number of rows that match the dynamic query

countWithDynamicQuery

long countWithDynamicQuery(DynamicQuery dynamicQuery,
                           Projection projection)

Returns the number of rows that match the dynamic query.

Parameters:

dynamicQuery - the dynamic query

projection - the projection to apply to the query

Returns:

the number of rows that match the dynamic query

fetchByPrimaryKey

T fetchByPrimaryKey(Serializable primaryKey)

Returns the model instance with the primary key or returns null if it could not be found.

Parameters:

primaryKey - the primary key of the model instance

Returns:

the model instance, or null if an instance of this model with the primary key could not be found

fetchByPrimaryKeys

Map<Serializable,T> fetchByPrimaryKeys(Set<Serializable> primaryKeys)

findByPrimaryKey

T findByPrimaryKey(Serializable primaryKey)
            throws NoSuchModelException

Returns the model instance with the primary key or throws a NoSuchModelException if it could not be found.

Parameters:

primaryKey - the primary key of the model instance

Returns:

the model instance

Throws:

NoSuchModelException

findWithDynamicQuery

<V> List<V> findWithDynamicQuery(DynamicQuery dynamicQuery)

Performs a dynamic query on the database and returns the matching rows.

Parameters:

dynamicQuery - the dynamic query

Returns:

the matching rows

findWithDynamicQuery

<V> List<V> findWithDynamicQuery(DynamicQuery dynamicQuery,
                                 int start,
                                 int end)

Performs a dynamic query on the database and returns a range of the matching 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.

Parameters:

dynamicQuery - the dynamic query

start - the lower bound of the range of matching rows

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

Returns:

the range of matching rows

QueryUtil.list( com.liferay.portal.kernel.dao.orm.Query, com.liferay.portal.kernel.dao.orm.Dialect, int, int)

findWithDynamicQuery

<V> List<V> findWithDynamicQuery(DynamicQuery dynamicQuery,
                                 int start,
                                 int end,
                                 OrderByComparator<V> orderByComparator)

Performs a dynamic query on the database and returns an ordered range of the matching 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.

Parameters:

dynamicQuery - the dynamic query

start - the lower bound of the range of matching rows

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

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

Returns:

the ordered range of matching rows
