Hi, If you are using 4.0.0.M2, I think this will do the job: function abs( int a, int b ) { return Math.abs( b - a ); } rule "get closer object" when $a : Agent( $num1 : num ) $b : Poste( $num2 : num ) not Poste( $num3 : num -> ( abs( $num1, $num3 ) < Math.abs( $num1, $num2 ) ) ) then // do something end If you are using 3.0.x, then it would be like: function abs( Integer a, Integer b ) { return Math.abs( b.intValue() - a.intValue() ); } rule "get closer object" when $a : Agent( $num1 : num ) $b : Poste( $num2 : num ) not Poste( $num3 : num -> ( abs( $num1, $num3 ) < Math.abs( $num1, $num2 ) ) ) then // do something end Hope it helps. Let us know if it works the way you need.

Dear all, It is possible to fire different set of rules, for the same working memory, by specifying some agenda filters? I have tried to do this, but only the rules from the first filter fire, the others not. Maybe I do something wrong? For example: workingMemory.fireAllRules(filter1); //do something workingMemory.fireAllRules(filter2); .......... where, the agenda filters are implemented like this: AgendaFilter filter1 = new AgendaFilter() { public boolean accept(Activation activation) { if (activation.getRule().getName().startsWith("aaa")) { System.out.println(activation.getRule().getName()); return true; } return false; } }; Best regards, Oana --------------------------------- Ahhh...imagining that irresistible "new car" smell?

You just need to create a class that implements this interface and that determines which events should be logged (see the javadoc of the filter and the working memory logger). See ActivationLogEventFilter and WorkingMemoryLogEventFilter for an example. You can add your filter to the logger using the addFilter(ILogEventFilter) method.

Hi everybody, I try to define an ILogEventFilter on the working memory logger, but I didn't find anything about how to do this, on the available documentation. Please help me with some information about the Logger and its functionality!

The WorkingMemoryFileLogger creates a list of relevant events (you can use filters to define which events are relevant for you) and just stores that as XML in the specified file. This log file is not intended to be used directly (as it is indeed very complex). The easiest way to see the content of the file in a user-friendly manner is to use the eclipse IDE and use the audit view to open the file. This view will then parse the content of the file and show it in a tree-like structure. If you would like to personally define how events are written out to a log file, you can always extend the abstract WorkingMemoryLogger and define how events should be written out in the logEventCreated(LogEvent) method. Any contributions to making auditing more configurable are greatly appreciated ! ;) Kris ----- Original Message ----- From: nicolae oana To: Rules Users List Sent: Monday, May 07, 2007 6:56 PM Subject: Re: [rules-users] Help needed in using working memory logger ! Dear Kris, I try to create a filter for my logger, in order to obtain some simple output (e.g. list modified objects), but the output is still very complex :( . I think that I did something wrong. Here is the code: final WorkingMemoryFileLogger logger = new WorkingMemoryFileLogger( workingMemory ); logger.setFileName( "log/testRules" ); ILogEventFilter filter = new ILogEventFilter(){ public boolean acceptEvent(LogEvent event){ if(event.getType()== LogEvent.OBJECT_MODIFIED) { logger.logEventCreated(event); return true; } return false; } }; logger.addFilter(filter); logger.writeToDisk(); With kind regards, Oana Kris Verlaenen <kris.verlaenen(a)cs.kuleuven.be&gt; wrote: You just need to create a class that implements this interface and that determines which events should be logged (see the javadoc of the filter and the working memory logger).
