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?
I beleive it'll work with primitive enums (int), but not enum classes.
If you tried it and it doesn't work, probably safe to assume it doesn't
support it :)

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.
