[jboss-jira] [JBoss JIRA] Commented: (JBRULES-2924) Planner: make it scala friendly and avoid casting in Solution.setScore() implementation: Solution interface gets a type S extend Score so Solution.getScore() returns S and Solution.setScore() now has a parameter S

Geoffrey De Smet commented on JBRULES-2924:
-------------------------------------------

[MAJOR] Solution now has a generic type of Score: Solution<S extends Score> (JBRULES-2924)
Your Solution implementation itself should not be generic, but it should define it's Score type through implements.
Before in *.java if you use a SimpleScore:
    public class ... implements Solution {
        ...
        public void setScore(Score score) {
            this.score = (SimpleScore) score;
        }
        ...
    }
After in *.java if you use a SimpleScore:
    public class ... implements Solution<SimpleScore> {
        ...
        public void setScore(SimpleScore score) {
            this.score = score;
        }
        ...
    }
Before in *.java if you use a HardAndSoftScore:
    public class ... implements Solution {
        ...
        public void setScore(Score score) {
            this.score = (HardAndSoftScore) score;
        }
        ...
    }
After in *.java if you use a HardAndSoftScore:
    public class ... implements Solution<HardAndSoftScore> {
        ...
        public void setScore(HardAndSoftScore score) {
            this.score = score;
        }
        ...
    }
