Re: Using a TreeSet, or other SortedSet

[Jakob Braeuchi]

hi jamo,
afaik ojb supports a single column only in the collection-descriptor. 
for more flexibility you could also use a query-customizer.
i think sorting the rows using sql is more effective than using compareTo.

My object is sorted by more than one column.  It is best, I think, to
utilize compareTo in this instance.  More important, would the below
method be as optimal as the method I purpose - if so, could I have it
sort by multiple columns?

hi jamo,
the collecton descriptor supports sorting. ie:
     <collection-descriptor
        name="allArticlesInGroup"
        element-class-ref="org.apache.ojb.broker.AbstractArticle"
        auto-retrieve="true"
        auto-update="true"
        auto-delete="false"
     >
        <orderby name="articleId" sort="DESC"/>
        <inverse-foreignkey field-ref="productGroupId" />
     </collection-descriptor>

I have a one to many relationship.  I need to retrieve the many in a
SortedSet as optimally as possible(instead of retrieving as a
collection then adding to a TreeSet)  What is the way to do this with
OJB?
