How to check Scrollable interface is empty?

Question

Returning from a hql query, how to check if a ScrollableResults object is empty?

scrollable.first?

Answer 1

ScrollableResults object has a method first()

first() returns boolean value.

TRUE if exists the first element, FALSE otherwise

ScrollableResults myScrollable ...

if (myScrollable != null && myScrollable.first()) {
    // add your business logic
}
