Re: [rules-users] Drools 3.0.6 support for enum's on jdk 1.5 ?
It's been a few days since this question was asked, and I am also
interested in the answer. I'm currently using an eval to get around
the problem, but is there any way to check enum equivalence directly
in drools?
Thanks,
Kris

Hello list,
I have a rule that generally speaking looks like this :
rule "ABC"
when
$f : FilteringStateConnector($campaignId : campaignId)
$campaign : Campaign(code == $campaignId
,$limitTypeEnum : limitTypeEnum, $limitByEventType :
limitByEventType)
// Check Budget limit pass conditions:
(
eval(BooleanLogging.trace(log, "DEBUG: " + ($limitTypeEnum ==
ENUM1.BudgetLimitFlag))) and
eval(BooleanLogging.trace(log, "DEBUG: Always here, right now"))
and
eval(BooleanLogging.trace(log, "DEBUG: " + ($limitByEventType ==
ENUM2._2_EXPOSED))) and
Campaign(code == $campaignId, limitTypeEnum ==
ENUM1.BudgetLimitFlag, limitByEventType == ENUM2._2_EXPOSED) and
eval(BooleanLogging.trace(log, "DEBUG: Right here, right now"))
) or (
...
)
then
...
end
The line """ eval(BooleanLogging.trace(log, "DEBUG: "
+
($limitTypeEnum == ENUM1.BudgetLimitFlag))) """ evaluates to
"true" in the
logs.
The line """ eval(BooleanLogging.trace(log, "DEBUG: "
+
($limitByEventType == ENUM2._2_EXPOSED))) """ as well. These are java
(eval)
checks for truth. If I try to use Drools to gain the rete optimization by
writing :
""" Campaign(code == $campaignId, limitTypeEnum ==
ENUM1.BudgetLimitFlag, limitByEventType == ENUM2._2_EXPOSED) """, It
never
reachers past that line. why is that? Can't Drools 3 check for truthness of
Enum conditionals ?
I would love to supply more information if required.
Help is highly appreciated,
Maxim.
