Re: [rules-dev] Better way to use And and Or
Hi,
In Drools 3.0, having the RCVRCOUNTRY and SNDRCOUNTRY as attributes
of the same bean, there is no better way of doing than:
when
m: ( (TransactionBean(RCVRCOUNTRY == "IRAQ", SNDRCOUNTRY == "US",
AMOUNT >
"3000")) ||
(TransactionBean(RCVRCOUNTRY == "IRAQ", SNDRCOUNTRY == "UK", AMOUNT
>
"3000")) ||
(TransactionBean(RCVRCOUNTRY == "IRAQ", SNDRCOUNTRY == "CAN", AMOUNT
>
"3000")) ||
(TransactionBean(RCVRCOUNTRY == "IRAN", SNDRCOUNTRY == "US", AMOUNT
>
"3000")) ||
(TransactionBean(RCVRCOUNTRY == "IRAN", SNDRCOUNTRY == "UK", AMOUNT
>
"3000")) ||
(TransactionBean(RCVRCOUNTRY == "IRAN", SNDRCOUNTRY == "CAN", AMOUNT
>
"3000")) )
then
end
In next version you can do:
when
m: TransactionBean( RCVRCOUNTRY == "IRAQ" |== "IRAN", SNDRCOUNTRY ==
"US" |== "CAN" |== "UK" )
then
end

Is there any other easier / better way to express this as a valid DRL? using
