How to implement the lazy loading similar to Vaadin Forum Topics List Page

How is the lazy loading of topics implemented on the Vaadin forum?
(
https://vaadin.com/forum#!/category/11566
)

I would like to implement something similar to that.

Thanks!

The source code for Tori is open source, so you can check for yourself:
ThreadListingWidget.java

Thanks very much for your help.
