Hello, Please can the community help me. I am attaching a WorkingMemoryListener to a session. In my DRL file, I have a number of declared types for which I want to "watch" when the process is running. How can I implement a "toString()" method in the DRL file for a declared type?

I have detailed the structure of my code below to make it clear what I am trying to do: DRL FILE -------- declare Foo low : double high : double score : int end Java Code ---------- ksession.addEventListener(new WorkingMemoryEventListener() { @Override public void objectInserted(ObjectInsertedEvent event) { System.out.println(*"Inserted: " + event.toString()*); /*// Here I would like to print out the data in the type Foo in a specific format.*/ } @Override public void objectUpdated(ObjectUpdatedEvent event) { System.out.println("Updated"); } @Override public void objectRetracted(ObjectRetractedEvent event) { System.out.println("Retracted"); } }); Thanks in advance for your help. -- View this message in context: http://drools.46999.n3.nabble.com/WorkingMemoryListener-Declared-Types-tp...

Hi, I haven't put Foo in my Java code as it is a transient type which I need to the rule processing and not really part of my ontology model. Anything which isn't part of ontology model but which I need to do the rule processing, I put those types in my DRL file. I'll explain what I am trying to achieve: I am writing some JUnit test classes and I would like to test for specific values for some attributes in the declared types in my DRL file. So in the example I gave, I would like to assert that during rule processing the value of Foo.score == 4. So basically I would like to query the working memory for this type and get the value of the score attribute. Is there a good way of doing this? -- View this message in context: http://drools.46999.n3.nabble.com/WorkingMemoryListener-Declared-Types-tp...

Nice, but is the result better than the default toString() that's doing much the same thing? -W On 07/08/2013, Stephen Masters <stephen.masters(a)me.com&gt; wrote: > Add commons beanutils to your project: > > <dependency> > <groupId>commons-beanutils</groupId> > <artifactId>commons-beanutils</artifactId> > <version>1.8.3</version> > </dependency> > > Then all you need is a class with a static method something like this: > > public static String objectDetails(Object o) { > StringBuilder sb = new StringBuilder(o.getClass().getSimpleName()); > > try { > @SuppressWarnings("unchecked") > Map<String, Object> objectProperties = BeanUtils.describe(o); > for (String k : objectProperties.keySet()) { > sb.append(", " + k + "=\"" + objectProperties.get(k) + > "\""); > } > } catch (IllegalAccessException e) { > return "IllegalAccessException attempting to parse object."; > } catch (InvocationTargetException e) { > return "InvocationTargetException attempting to parse object."; > } catch (NoSuchMethodException e) { > return "NoSuchMethodException attempting to parse object."; > } > > return sb.toString(); > } > > > > On 7 Aug 2013, at 10:19, droolster <quant.coder(a)gmail.com&gt; wrote: > >> Hi, >> >> I haven't put Foo in my Java code as it is a transient type which I need >> to >> the rule processing and not really part of my ontology model.
