findAll

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

Returns a range of all the m d r rule 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.

Parameters:

start - the lower bound of the range of m d r rule groups

end - the upper bound of the range of m d r rule groups (not inclusive)

Returns:

the range of m d r rule groups

Throws:

SystemException - if a system exception occurred
