What counts as "activity" for Http2Session#setTimeout?

[murgatroid99]

The documentation says

Used to set a callback function that is called when there is no activity on the Http2Session after msecs milliseconds.

What exactly counts as "activity" there?

More specifically: does all incoming data count? Do writes initiated by the local application count? Does every kind of http2 frame count, or just some of them?

To my best understading, I think all data transfered (both ways) count.

Everything but WINDOW_UPDATE frames should count.
