Is it possible to remove existing PagingFilter and add new one in same query

Question

For some requirement I need to write code something like below and not sure how it is possible -

Query query = new Query();         
query.setCriteria(completeCriteria);

query.setResultFilter(new PagingFilter(minitems,pageSize));

String [] totalComURIs = query.executeQuery();  

/* Here I want to Remove the exiting PagingFilter and execute the same query with 
   new PagingFilter as below- again */    
query.setResultFilter(new PagingFilter(minitems,(pageSize +5)));

/* This  increment of 5 is not fix and getting calculated with the help of some 
   code after executing query with first PagingFilter */
String [] AllitemURIs = query.executeQuery();

Answer 1

I would expect that setting the result filter again would reset it, so if you would call:

query.setResultFilter(myUpdatedPagingFilter);
String [] AllitemURIs = query.executeQuery();

that should work (but I am guessing here, I didn't test it).

If it doesn't then you can always revert to creating a new Query object:

query = new Query();         
query.setCriteria(completeCriteria);  
query.setResultFilter(myUpdatedPagingFilter);
String [] AllitemURIs = query.executeQuery();

That surely should work.

It's good to have a nice method to handle different filters.

Example:

// Calling method
String[] totalComURIs = ExecuteQuery(criteria, new PagingFilter(currentPosition, pageSize));
String[] AllitemURIs = ExecuteQuery(criteria, new PagingFilter(currentPosition, pageSize+5));

// Method returns String Array
public String[] ExecuteQuery(Criteria criteria, ResultFilter resultFilter)
{
    Query query = new Query();
    query.setCriteria(criteria);
    query.setResultFilter(resultFilter);
    return query.executeQuery();
}
