[rules-users] Custom-Operator - No access to FactHandles?
Hello, some of our custom operators need to access already inserted facts at runtime. Therefore we extended org.drools.base.BaseEvaluator. The provide methods, i. e. public boolean evaluate(InternalWorkingMemory workingMemory, InternalReadAccessor extractor, Object object, FieldValue value), state, amongst others, a parameter workingMemory of type org.drools.common.InternalWorkingMemory. When calling workingMemory.getObjects() we receive a UnsupportedOperationException. The question is whether it is possible to access facts in a KnwoledgeSession at runtime or not. Alternatively we could provide the objects in question as globals and call workingMemory.getGlobal(), but that seems to me like somewhat bad architecture. Any suggestions are welcome.

Re: [rules-users] Custom-Operator - No access to FactHandles?
I think there is a fundamental misunderstanding in the use you are trying to do with custom operators. Custom operators are supposed to be used to correlate 2 values, that may be lists, but not do search in the working memory, as that would be extremely inefficient. If you need to process sets of facts, then you probably need an accumulate function, not an operator... Can you clarify what kind of operator are you trying to implement?

Does the DRL compile without error? Also, your code uses the old API. Try
KnowledgeBuilder kBuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
DecisionTableConfiguration dtConf =
KnowledgeBuilderFactory.newDecisionTableConfiguration();
dtConf.setInputType( DecisionTableInputType.XLS );
Resource resource = ResourceFactory.newClassPathResource( xlsPath,
getClass() );
kBuilder.add( resource, ResourceType.DTABLE, dtConf );
if( kBuilder.hasErrors() ){
KnowledgeBuilderErrors errors = kBuilder.getErrors();
for( KnowledgeBuilderError err: errors ){
System.err.println( err.toString() );
}
throw new IllegalStateException( build errors );
}
Or, if you want to see the generated DRL, use the above (slightly modified)
for the DRL, but do check for errors!

Thx man!
Was getting pretty pissed ... :P
Only now I have a different problem when actually using the decision table:
public RuleBase readDecisionTable() throws Exception
{
SpreadsheetCompiler converter = new SpreadsheetCompiler();
String drl = converter.compile(CheckAccepted.xls,
InputType.XLS );
System.out.println(drl);
PackageBuilder builder = new PackageBuilder();
builder.addPackageFromDrl( new StringReader( drl ) );
Package pkg = builder.getPackage();
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
ruleBase.addPackage( pkg );
return ruleBase;
}
I get this error:

[rules-users] Why is Drools called Drools?
This is something I get asked on a semi-regular basis and I don't have a good answer for it, so I thought I'd post it to the mailing list and hope someone can tell the story. Is there anyone out there who can explain how the name Drools was settled on? ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
