Would anyone happen to know if such an API exists in drools?

Hi, I'm aware of that but was looking for a way to do it using some API. I am inserting some objects to the engine and would like to declare them as events "automatically" before inserting. I could generate the snippet shown in the doc and add it to the knowledge base but was wondering if the same thing could be accomplished using existing API.

OK, just wanted to make sure. Is my understanding correct that if I want to use temporal constraints in some rules I can declare a fact as an event but I can still use it as a plain fact in other rules?

From what I understand after reading the documentation is that the event declaration applies to the whole knowledge base?
