Hibernate version:3

In my current app, I have a loop that builds a where clause in HQL. Here it is.




Now, I am trying to move this code from Hibernate 2.1.7 useing a session.find to Hibernate 3 using a session.createCriteria. As you can see, I have both "and" and "or" (disjunction) in this HQL. How would I build this using the createCreiteria dynamically? I do not know how many Restrictions I may have. From the looks of the doc, I need to know this in order to code it correctly. Am I missing something here?

The solution I came up with was to create a new Criterion within the loop, add it to somekind of datastructure, then reassemble a new Criterion using the Expression.or method. Code snippet below:

ArrayList expressions = new ArrayList();
for loop{
Criterion c = Expression.like("example", example);
expressions.add(c);
} // for

Iterator ci = expressions.iterator();
Criterion searchAllCriteria = null;
while(ci.hasNext()) {
if(searchAllCriteria == null)
searchAllCriteria = Expression.or((Criterion)ci.next(), (Criterion)ci.next());
else
searchAllCriteria = Expression.or(searchAllCriteria, (Criterion)ci.next());
} // while

criteria.add(searchAllCriteria);

Hope this helps,
