[jboss-jira] [JBoss JIRA] (JBRULES-3328) Add an API to allow access to the constraint occurrences of a solution

[ https://issues.jboss.org/browse/JBRULES-3328?page=com.atlassian.jira.plug... ] Geoffrey De Smet commented on JBRULES-3328: ------------------------------------------- Copied from the change: Hi David, Thanks for sharing this change. Even though I don't want to change the BestSolutionEvent API like this (as it leaks the solver's "working" WorkingMemory), it does give me a very good insight on what you want to do. Furthermore, I 've recently specced out that the user provides a bestSolution and the workingMemory is a clone of that. So that means the bestSolution is never in the WorkingMemory. See the changes here: https://github.com/droolsjbpm/drools-planner/commit/5690541a567e5db36c6f2... Next improvement in this will be to split up the SolutionDirector into SolutionDirectorFactory (holds RuleBase) and SolutionDirector (holds WorkingMemory) so the user can use the same SolutionDirectorFactory to create it's own, isolated SolutionDirector. That would mean you'd have to take the bestSolution and set it on your SolutionDirector (instead of sharing a WorkingMemory with the Solver). Can you live with that? It might be a small performance hit (but premature optimization is the root of all evil because not doing it would hinder multi-threaded solving in the future). -- This message is automatically generated by JIRA.
