-----------------------------------------

I think that should be feasible, yes.

> When implementing custom WindowAssigners, it is possible to need different implementations
of the {{Window}} class (other than {{TimeWindow}}). In such cases, it is not possible to
use the existing triggers (e.g. {{EventTimeTrigger}}) because it extends from {{Trigger<Object,
TimeWindow>}} which is (unnecessarily?) specific.
> It should be possible to make that class more generic by using {{EventTimeTrigger<T,
W extends Window> extends Trigger<T, W>}} instead.
