List<GenericValue> to EntityListIterator

[g.fitini]

Hi to everyone, i’ve done the following query with the IN clause.

    List<GenericValue> XXXList = delegator.findList("XXX", null, null, null, null, false);
       
        List<GenericValue> listIt =
                 EntityUtil.filterByCondition(XXXList,
                EntityCondition.makeCondition("field",
                EntityOperator.IN, listInClause));

QUERY : select * from XXX where field IN (..,..,..,...)


now, i want to transform ‘listIt’ , to EntityListIterator. How can do that?

I need to transform it to a EntityListIterator because i’ve done a custom service, that wrap ‘performFind’ service.
So, i’ve the same OUT parameters .

Any suggestions??
Thanks

Using delegator.find() instead of delegator.findList() would help.

Just to be sure: You want to Iterate over the list or you are having a problem with the clauses?

For the former: You can either get the iterator from the List Object:

Iterator it= listIt.iterator();
while(it.hasNext()) {
   GenericValue obj = it.next();
   // Your code here

}


or you can iterate like this:

for(GenericValue obj : listIt){
   // Your code here...

}
