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. Attached you can find the full code
