Geoffrey De Smet created JBRULES-3461: ----------------------------------------- Summary: Planning entity's hashCode() (used by tabu accepter) vs solutionHashCode() (used by solution equality) Key: JBRULES-3461 URL: https://issues.jboss.org/browse/JBRULES-3461 Project: Drools Issue Type: Task Security Level: Public (Everyone can see) Components: drools-planner Reporter: Geoffrey De Smet Assignee: Geoffrey De Smet Discussion started in JBRULES-3439. Summary: 1) Planning entity solutionHashCode() and hashCode() are both needed. What's the difference and why not one method? Reason: solutionHashCode() must include the variables, and hashCode() must not include the variables 2) solutionHashCode() will be obsolete once Solution.equals/hashCode() gets implemented automatically by planner by just looking at the entities and variables. 3) What if the users does want to include the variables in it's equals method. Can the tabu accepter work on some sort of entity.getId() value? Note: It can not work with IdentityHashMap because there will be different instances (especially in multi-threading or multi-vm). -- This message is automatically generated by JIRA.
