Thank you very much~
1- You don't "retract", you can set it to null, same way as set to an
object.
Is it in java or in drool?
...? It's a Java object, made visible to DRL code.
If I understand correct, global variable is not
really inserted into the working memory,right?
Yes.
Global just ensure drool can
see the variable?
Yes.
2-Several ways, simple is to use KnowledgeSession's
getFactHandles, and
retract them. Or dispose the entire Session, and create another one, which
might be faster.
You mean the working memory belongs to the Session not knowledgeBase?
Yes.
Because I have to keep the knowledgebase running all the time, I have
to
ensure each fire() don't leave any useless facts in the working memeory.
Now you know how to.
