Re: [rules-users] Drools performance

You can't set Drools to read N events per second. Performance depends on several factors, so asking for how many events doesn't make sense. Benchmark. Who should admit a delay? -W -- View this message in context: http://drools.46999.n3.nabble.com/Drools-performance-tp4027355p4027367.html

Re: [rules-users] How to improve performance with large number of rules and facts ?

Add this after your last insertion: clock.advanceTime(1, TimeUnit.MILLISECONDS); I'm not sure why you have to do this, though. Perhaps it is a bug in Drools. -- View this message in context: http://drools.46999.n3.nabble.com/Event-Processing-in-Drools-tp4025029p4025161.html Sent from

Re: [rules-users] Memory-Problemwith instance of ReteooStatefulSession

You have (at least) two different fact classes: Alert and Information (not just one, as you write). The rule you have shown has only two patterns - I was asking for one with three patterns (as I was thinking they had all to be of the same class). If you retract an Alert as soon as it is

This code may work, and then it may not: it depends on (Java) code not shown. If it works, it will loop. -- View this message in context: http://drools.46999.n3.nabble.com/Abstracting-Rules-using-extends-tp4023217p4023226.html Sent from the Drools: User forum mailing list archive at

Re: [rules-users] Abstracting Rules using extends

Using a drl-defined class for defining the constants is all right, but these values have to be used while creating a Vehicle object. People maintaining the rules may not be the ones responsible for the code creating the facts, and that's where these values will have to be used for setting the

So I'm not going to repeat the Expert User Guide here - read for yourself. Some pointers: * rule attribute agenda-group * API call class AgendaGroup method setFocus() * rule attribute auto-focus Being in one file or other doesn't matter with these, although there's an undocumented feature: Using

Re: [rules-users] Structuring rules in Drools

To figure out a hierarchical structure among rules isn't a very clear definition... Rules (like many other logical entities in some programming environment) are written in compilation units - DRL file, which imposes one hierarchical structure. Then, they are subordinate to packages (much like

Re: [rules-users] Decision table call external method

If there is just one object of class XMLTool and all addNode() calls should refer to this single object, you should do what Vincent suggested by making this single object accessible via a DRL global variable, or by using the singleton design pattern (as in Java). Adding this object as a fact and

Re: [rules-users] why java.util.Map doesn't work on RHS update

Read the definition of lock-on-active: it inhibits the firing of your second rule. It is almost certainly a bad idea to use Map objects like this. Beans are much better suited, as you could write rules such as when MyType( year == 2012, state == null ) then modify(...) -W -- View this

Re: [rules-users] Loop Drools on Multi Element

Using forall isn't so complicated. You can use the simplified form, where the condition to be satisfied is written in the pattern selecting the domain. rule setPriority when $order: OrderType( priority != high ) forall ( OrderLineType( quantity 2 ) from $order.lineItem ) then

Re: [rules-users] Loop Drools on Multi Element

Re: [rules-users] Alternative to instanceof when matching against multiple concrete types under the same hiearchy?

Inverting the order of patterns (and following Lisa's idea) makes the problem go away: rule asdf when OtherType( $member : member ) Interface( this == $member ) then // do whatever with $member end This can be constrained to a subset of subclasses if there is also ConcreteType3
