Calling functions in other classes

[lastdance]

I've been reading S2 documentation like crazy, and I'm pretty sure the answer is 'no' but I'm going to throw out the question anyway:

Is there any possible way to call functions from a different view than the one you're currently on? For example, the EntryPage class has a function print_comments. But what if I want to print the subjects of the 5 latest comments on the Recent view (maybe in the sidebar)? The RecentPage class doesn't include that function, so I'm assuming there's no way to call it unless the core was rewritten to add it into RecentPage and allow it to take parameters so it knows which comments to pull back. Am I correct in that assumption?

I'll gladly take the question elsewhere if this isn't the right place. Any direction would be so much appreciated.

It's the most complex comm setup I've seen on LJ, so I'm fascinated by how it works.

The reason I think they're using an external service is because the comment count in the sidebar sometimes lags behind the actual comment count. Also, not all of the popular posts appear on the front page. That makes me think they're scraping the content intermittently somehow and then auto-updating the sidebar.

No idea at this point how that works. Once all the S2 and API documentation is done, will it be clear to me? ;)

Hmm, probably not. If they are using a third-party API, and it's not entirely S2, then no amount of documentation on our end will make it clear, I'm afraid!

They're definitely using some kind of off-site tracker in PHP. You can see calls to 0x0 images in the page source (tables and un-validated HTML, ewww).
