[jboss-jira] [JBoss JIRA] Created: (JBRULES-544) getQueryResults behavior: return null

getQueryResults behavior: return null -------------------------------------- Key: JBRULES-544 URL: http://jira.jboss.com/jira/browse/JBRULES-544 Project: JBoss Rules Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Reteoo Affects Versions: 3.0.4 Reporter: Edson Tirelli Assigned To: Edson Tirelli Fix For: 3.0.5, 3.1-m1 AS REPORTED BY GEOFFREY DE SMET: --------------------------------------------------------- Thanks Edson for fixing the getQueryResults() method in JBRULES-539. I found something interesting I'd like to bring under discussion: WorkingMemory.getQueryResults() returns null when: - no such query exists in the drl's. I would have expected an IllegalArgumentException, in the spirit of fail-fast, but it's not that big a deal. - but it also returns null when the query has 0 results. I would have expected a QueryResults instance with .size() == 0. It seems inconsistent with WorkingMemory.getObjects(X.class) which does return an empty list, instead of null. [tested on the branch for 3.0.x for Rete] What do you think? -- With kind regards, Geoffrey De Smet -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
