Examples of javax.jdo.Query.cancel()

javax.jdo.Query.cancel()
Method to cancel an executing query in the specified thread. If the underlying datastore doesn't support cancellation of queries this will throw JDOUnsupportedOptionException. If the cancellation fails (e.g in the underlying datastore) then this will throw a JDOException. @since 2.3


            // Wait a couple of millis such that the other thread can start query execution
            Thread.sleep(MAIN_SLEEP_MILLIS);


            // cancel query 
            query.cancel(t);
            if (!isQueryCancelSupported()) {
                fail(ASSERTION_FAILED,
                     "Query.cancel should throw a JDOQueryInterruptedException, " + 
                     "if query canceling is not supported ");
            }
