[jboss-jira] [JBoss JIRA] Commented: (JBRULES-1040) Multi-pattern accumulate support
[ http://jira.jboss.com/jira/browse/JBRULES-1040?page=comments#action_12378044 ]
Edson Tirelli commented on JBRULES-1040:
----------------------------------------
Geoffrey, look at my example:
"All connectives used in the source must be explicitly defined, like the
"and" in the above example. "
So, you need to use "and", "not", "exists", etc in your
source patterns in the accumulate:
rule "constraintsBroken"
when
$multipleQueensHorizontal : Long()
from accumulate(
$q1 : Queen($id : id, $y : y) and
Queen(id > $id, y == $y)
, count($q1)
);
$multipleQueensAscendingDiagonal : Long()
from accumulate(
$q2 : Queen($id : id, $ascendingD : ascendingD) and
Queen(id > $id, ascendingD == $ascendingD)
, count($q2)
);
$multipleQueensDescendingDiagonal : Long()
from accumulate(
$q3 : Queen($id : id, $descendingD : descendingD) and
Queen(id > $id, descendingD == $descendingD)
, count($q3)
);
then
scoreCalculator.setScore( - $multipleQueensHorizontal -
$multipleQueensAscendingDiagonal - $multipleQueensDescendingDiagonal));
end
Let me know....
BTW, functions DOES work.

[Edson said there might be already such an issue, but I couldn't find it looking
through jira.]
Something like this should be possible:
$multipleQueensHorizontal : Long()
from accumulate(
$q1 : Queen($id : id, $y : y);
Queen(id > $id, y == $y);
, count($q1)
);
