Interface JQuery

public interface JQuery

Query interface. Queries are reusable objects that can be stored in static variables. Once built, they can be re-used in parallel in different threads.

It is suggested not to use start and maxCount parameters in PersistenceManager#runQuery(Query, Object, int, int). Instead try to use bidirectionality of query iterator. For example: run the query, display first screen and keep the result. When the user clicks next/previous, simply iterate forward/backward. Release the result when the user stops viewing data.

Use one of PersistenceManager#get(JQuery methods to run the query.
