[rules-users] Drools basic questions.

I am new to drools, so i have some basic doubts. 1. what does the dollar sign represent in the following rule? what is the difference when u prefix and dont prefix a variable with the dollar sign? - $stilton : Cheese( type == "stilton" ) Cheesery( cheeses contains $stilton ) 2. what is the difference between the following rule statements ? - cheapStilton : Cheese( type == "stilton", price < 10 ) and - cheapStilton : Cheese( type == "stilton", price < newPrice) how does the rule base get access to the variable newPrice, in the above rule statement? Please help. Thank you. -- View this message in context: http://www.nabble.com/Drools-basic-questions.-tf3770003.html#a10658753 Sent from the drools - user mailing list archive at Nabble.com.
