[jboss-jira] [JBoss JIRA] Resolved: (JBRULES-1040) Multi-pattern accumulate support

[Edson Tirelli (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBRULES-1040?page=all ]

Edson Tirelli resolved JBRULES-1040.
------------------------------------

    Fix Version/s: 4.0.2
                       (was: FUTURE)
       Resolution: Done

Support for multi-pattern accumulate was added. Example:

Rule: Add to the Cheesery, all Cheese pieces whose type there are Persons who like it:

rule "MultiPatternAccumulate" salience 80
    when
    	$cheesery    : Cheesery( totalAmount > 30 ) 
    	                       from accumulate( $person : Person( $likes: likes) and $cheese : Cheese( type == $likes ),
                                                init( Cheesery cheesery = new Cheesery(); ),
    	                                        action( cheesery.addCheese( $cheese ); ),
    	                                        reverse( cheesery.removeCheese( $cheese ); ),
                                                result( cheesery ) );
    then
        results.add( $cheesery );
end  

All connectives used in the source must be explicitly defined, like the "and" in the above example.

Support still needs to be added to the XML parser and documentation needs to be written. Will open new tickets for these jobs.

> Something like this should be possible:
>   $multipleQueensHorizontal : Long()
>     from accumulate(
>         $q1 : Queen($id : id, $y : y);
>         Queen(id > $id, y == $y);
>       , count($q1)
>     );
