Re: [rules-users] Question about getObjects() on workspace with defeasible belief system
Easiest thing is to look at the code:
https://github.com/droolsjbpm/drools/blob/master/drools-core/src/main/jav...
https://github.com/droolsjbpm/drools/blob/master/drools-core/src/main/jav...
And tests:
https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/test...
As Davide said, this is highly experimental. It’s likely we won’t use a ‘neg’ entry point
in the future to handle negated facts, but instead provided a meta property.

A quick question on your example code before I try it:

Is myNegatedObject just the set that getObjects() returned or is there
another enumeration method I should use? Ie do I Iook for a neg entry
point object for each object I get back from ksession.getObjects() or do
I need to acquire a collection from another place (as well) if I want to
enumerate everything in the workspace for my dumpWorkspace() pretty printer?
Thanks
