Method Detail

findByG_C

List<PortletItem> findByG_C(long groupId,
                            long classNameId)
                            throws SystemException

Returns all the portlet items where groupId = ? and classNameId = ?.

Parameters:

groupId - the group ID

classNameId - the class name ID

Returns:

the matching portlet items

Throws:

SystemException - if a system exception occurred

findByG_C

List<PortletItem> findByG_C(long groupId,
                            long classNameId,
                            int start,
                            int end)
                            throws SystemException

Returns a range of all the portlet items where groupId = ? and classNameId = ?.

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 PortletItemModelImpl. 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:

groupId - the group ID

classNameId - the class name ID

start - the lower bound of the range of portlet items

end - the upper bound of the range of portlet items (not inclusive)

Returns:

the range of matching portlet items

Throws:

SystemException - if a system exception occurred

findAll

List<PortletItem> findAll()
                          throws SystemException

Returns all the portlet items.

Returns:

Throws:

SystemException - if a system exception occurred

findAll

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

Returns a range of all the portlet items.

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 PortletItemModelImpl. 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 portlet items

end - the upper bound of the range of portlet items (not inclusive)

Returns:

the range of portlet items

Throws:

SystemException - if a system exception occurred

findAll
