示例1: getTotalItemsCnt
import org.mongodb.morphia.query.Query; //导入方法依赖的package包/类
private Long getTotalItemsCnt(Query<V> q, ServiceQuery<?> serviceQuery, List<V> results) {
if (!serviceQuery.isCountTotalItems()) {
return null;
}
if (results.size() > q.getLimit()) {
throw new RestDslException("Implementation error: results size must be not greater than limit, was " +
results.size() + " but limit was: " + q.getLimit());
}
if (serviceQuery.getCountOnly()) {
return q.countAll();
}
// if getLimit == 0 then we need to count anyway
if (results.size() == 0 && q.getOffset() == 0 && q.getLimit() > 0) {
return 0L;
}
// if size is equal 0 it could be that offset is too big, or we just have 0 elements in total - must count
if (results.size() != 0 && results.size() < q.getLimit()) {
return (long) (q.getOffset() + results.size());
} else {
