Geoffrey De Smet created DROOLS-2440: ---------------------------------------- Summary: API gap: KieBase.getGlobalType(String identifier) which returns the class of the global field Key: DROOLS-2440 URL: https://issues.jboss.org/browse/DROOLS-2440 Project: Drools Issue Type: Enhancement Components: core engine Affects Versions: 7.6.0.Final Reporter: Geoffrey De Smet Assignee: Mario Fusco This is needed to avoid try-catching kieSession.setGlobal(...) in for example optaplanner. This code {code} kieSession.setGlobal("scoreHolder", workingScoreHolder); {code} throws {code} Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: Illegal class for global. Expected [org.optaplanner.core.api.score.buildin.hardsoft.HardSoftScoreHolder], found [org.optaplanner.core.api.score.buildin.hardsoftlong.HardSoftLongScoreHolder]. at org.drools.core.impl.StatefulKnowledgeSessionImpl.setGlobal(StatefulKnowledgeSessionImpl.java:1189) at org.optaplanner.core.impl.score.director.drools.DroolsScoreDirector.resetKieSession(DroolsScoreDirector.java:79) at org.optaplanner.core.impl.score.director.drools.DroolsScoreDirector.setWorkingSolution(DroolsScoreDirector.java:69) {code} because the user didn't align his global field ScoreHolder type with his domain classes score type. Instead they should get {code} IllegalStateException: your global field ScoreHolder type (...) does not align with your domain classes score type (...). {code} To do this, we need to have KieBase.getGlobalType("scoreHolder") return HardSoftScoreHolder.class, so I can check it's not equal HardSoftLongScoreHolder.class, during bootstrap, instead of try-catching every setGlobal() call. Furthermore, I believe this should be added in the public api - it is clearly an api gap. But I can work with adding this in the internal api too. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
