Adds IEvent interface for Record event support #56

Thanks for your PR. Did a quick code review on my phone, looks good. Assigning to Lex for further testing.
In terms of performance, I expect record component getters to be faster than normal class getter methods, but event posting and subscribing to be around the same as normal classes. Even if performance ends up being the same, having the record syntax for some events would be nice.

Why is Object.class added?

When I was running the tests I kept getting a weird error where it was trying to cast Object to IEvent when getting the Listener list. It's because the get parent call returns the class it extends, not the interface it implements so the record test class' parent was Object

Odd... The record's parent class should be java.lang.Record as that's what all record classes extend.

Yes, this is what I thought at the time especially because when looking at it in ClassNode that's what it says. However, the Class<?> superclass = eventClass.getSuperclass(); call was giving Object (otherwise I assume I would've seen the same casting exception but for Record)

My assumption was that the record events might gain some performance from the default implementation on methods such as Either way, I'll re-run them on a smaller sample size as you suggested and get back with the results. |
Adds, and migrates all references, to the IEvent interface to allow creating record based events in the future.
I'm not sure if this was the correct way to do this, but I ran the tests against everything I changed, and added one for the Record events because I wasn't sure it'd work with phases, and they passed. I was going to run the performance tests, and see if there was any notable difference for records, but it was giving a 12 hour ETA so I decided against doing that.
