Hello,

i got the following hibernate mapping;
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">

<hibernate-mapping>

<class name="com.wf.core.wOffer" table="WATEROFFER" lazy="true">
<id name="id" type="long">
<generator class="native"/>
</id>
...
...
<set name="tenderOffers" inverse="true" batch-size="10">
<key column="waterOffer"/>
<one-to-many class="com.wf.core.TenderOffer"/>
</set>
</class>

</hibernate-mapping>

and default lazy is false, since i using hibernate 2.0x

is this the way to implement lazy with the batch-size?
i just want to increase the proformance of the hibernate

</set>

I use following class to set the object;

Code:

public TenderOffer getTheOffer() {
        Set theOffers = getTenderOffers();
        Iterator it = theOffers.iterator();
        while (it.hasNext()) {
            TenderOffer to = (TenderOffer) it.next();
            
            if (to.getOfferer().getId().equals(getBuyer().getId())
                && to.getAccepted().booleanValue()) {
                return to;
            }
        }
        
        return null;
        
    }

Insted of getting the entire object, what would be the best way to increase the preformance, how can i get the pointer to the object?
