A cosmetic change but:
1. gives better encapsulation and Event based classes do not look that

The only thing that might be against is that instead of if else if else
if we have method invocations which might (or not?) be less efficient.
+1, it's more object oriented, if you see such instanceof cascades it
always looks as something is horribly wrong with the code. BTW, I doubt
that a method invocation is slower than an instanceof test.
