Re: [rules-users] Accumulate function, events and stream processing

Tried, but won't work. Ok, step by step. 1- DRL File Event declared, FirstRule won't work and SecondRule is working properly (neither count or sum) declare StateEvent @role( event ) end rule "FirstRule" when Number( $total : doubleValue ) from accumulate( StateEvent(itemName=="Temperatura", $val : newState) over window:length( 5 ), count ( 1 )) then System.out.println("" + $total); end rule "SecondRule " when StateEvent(itemName=="Temperatura", $val : newState) then System.out.println("" + ((DecimalType)$val).toBigDecimal().doubleValue()); end 2. Important lines from Engine starting (notice that i'm using stateful session) KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add(ResourceFactory.newClassPathResource(RULES_CHANGESET, getClass()), ResourceType.CHANGE_SET); KnowledgeBaseConfiguration kbaseConfig = KnowledgeBaseFactory.newKnowledgeBaseConfiguration(); kbaseConfig.setOption( EventProcessingOption.STREAM ); KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(kbaseConfig); StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); 3.
