Criteria with multiple table Eager join

Question

Code

        DetachedCriteria criteria2 = DetachedCriteria.forClass(MasterResult.class);
        criteria2.createAlias("masterCCHolders", "masterCCHolders", CriteriaSpecification.INNER_JOIN);
        criteria2.createAlias("masterFlights", "masterFlights", CriteriaSpecification.INNER_JOIN);
        criteria2.createAlias("masterPassengers", "masterPassengers", CriteriaSpecification.INNER_JOIN);
        criteria2.createAlias("masterVendors", "masterVendors", CriteriaSpecification.INNER_JOIN);

this is generating following query

select
    this_.id as id49_4_,
    this_.adults as adults49_4_,
    this_.bookingdate as bookingd3_49_4_,
    this_.children as children49_4_,
    this_.depart_date as depart5_49_4_,
    this_.email1 as email6_49_4_,
    this_.fareprice as fareprice49_4_,

    this_.last_name as last10_49_4_,

    masterccho2_.id as id6_,
    masterccho2_.id as id47_0_,
    masterccho2_.first_name as first2_47_0_,
    masterccho2_.last_name as last3_47_0_,
    masterccho2_.master_booking_id as master4_47_0_,
    masterflig3_.master_booking_id as master5_49_7_,
    masterflig3_.id as id7_,
    masterflig3_.id as id50_1_,
    masterflig3_.direction as direction50_1_,
    masterflig3_.fromcode as fromcode50_1_,
    masterflig3_.master_booking_id as master5_50_1_,
    masterflig3_.tocode as tocode50_1_,
    masterpass4_.master_booking_id as master6_49_8_,
    masterpass4_.id as id8_,
    masterpass4_.id as id46_2_,
    masterpass4_.first_name as first2_46_2_,
    masterpass4_.last_name as last3_46_2_,
    masterpass4_.master_booking_id as master6_46_2_,
    masterpass4_.middle_name as middle4_46_2_,
    masterpass4_.type as type46_2_,
    mastervend5_.master_booking_id as master4_49_9_,
    mastervend5_.id as id9_,
    mastervend5_.id as id48_3_,
    mastervend5_.locator as locator48_3_,
    mastervend5_.master_booking_id as master4_48_3_,
    mastervend5_.name as name48_3_ 
from
    masterresult this_ 
left outer join
    masterccholder masterccho2_ 
        on this_.id=masterccho2_.master_booking_id 
left outer join
    masterflight masterflig3_ 
        on this_.id=masterflig3_.master_booking_id 
left outer join
    masterpassenger masterpass4_ 
        on this_.id=masterpass4_.master_booking_id 
left outer join
    mastervendor mastervend5_ 
        on this_.id=mastervend5_.master_booking_id 

Query returns 20 rows, which fine, but this also creates 2o Objects of masterResult.

Model structures is like

MasterResult Contains

• Set of masterCCHolders,
• Set of masterFlights,
• Set of masterPassengers,
• Set of masterVendors

How to solve, this issue ?

1 MasterResult Contains

• 2 Set of masterCCHolders ,
• 2 Set of masterFlights ,
• 5 Set of masterPassengers ,
• 1 Set of masterVendors,

So total 2*2*5=20 records.

How can I have one masterResult object which contains set of masterCCholder of size 2, set of masterflights of size 2, set of masterpassengers size of 5 and so on.

Thanks
