executeQuery

public QueryResults executeQuery(java.util.List l)
                          throws QueryExecutionException

Exectute the query and return the results. A reference to the results is also held to allow them to be iterated over. If you plan on re-using this data source then you should call: clearResults() to free up the references to the results.

Parameters:

l - The List of objects to execute the query on.

Returns:

The results.

Throws:

QueryExecutionException - If the query cannot be executed, or if the query is set to return objects rather than "columns".
