When the type of the results is known the preferred usage would be:
Query<Entity>query=Query.newGqlQueryBuilder(Query.ResultType.ENTITY,"select * from kind").build();QueryResults<Entity>results=datastore.run(query);while(results.hasNext()){Entityentity=results.next();...}
When the type of the results is unknown you can use this approach:
Queryquery=Query.newGqlQueryBuilder("select __key__ from kind").build();QueryResultsresults=datastore.run(query);if(Key.class.isAssignableFrom(results.getResultClass())){QueryResults<Key>keys=(QueryResults<Key>)results;while(keys.hasNext()){Keykey=keys.next();...}}
