Method Detail

findByC_C

List<RatingsEntry> findByC_C(long classNameId,
                             long classPK)
                             throws SystemException

Returns all the ratings entries where classNameId = ? and classPK = ?.

Parameters:

classNameId - the class name ID

classPK - the class p k

Returns:

the matching ratings entries

Throws:

SystemException - if a system exception occurred

findByC_C

List<RatingsEntry> findByC_C(long classNameId,
                             long classPK,
                             int start,
                             int end)
                             throws SystemException

Returns a range of all the ratings entries where classNameId = ? and classPK = ?.

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 RatingsEntryModelImpl. 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:

classNameId - the class name ID

classPK - the class p k

start - the lower bound of the range of ratings entries

end - the upper bound of the range of ratings entries (not inclusive)

Returns:

the range of matching ratings entries

Throws:

SystemException - if a system exception occurred

findAll

List<RatingsEntry> findAll(int start,
                           int end)
                           throws SystemException

Returns a range of all the ratings entries.

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 RatingsEntryModelImpl. 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 ratings entries

end - the upper bound of the range of ratings entries (not inclusive)

Returns:

the range of ratings entries

Throws:

SystemException - if a system exception occurred
