[rules-users] query or global

[thomas kukofka]

Hello again,

what are disadvantages and advantages of the following possibillities to to
get access to working memory facts from outside:


   - -uses a query:

in drl:

query "queryname"
    ...
end

in java code

queryResults results = workingMemory.getQueryResults( "queryname" );

   - -use globals that store facts:

global java.util.HashMap service
rule "XY"
    when
        f: FactX ()
    then
        ResultFact resultFact = new ResultFact();
        service.put(f.getName(), resultFact);
        insert(resultFact);
end


kind regards
tom
