RE: [rules-users] Drools basic questions.

1. See previous email about identifiers. The dollar sign has no significance other than some people find it makes identifying variables in a rule easier. 2. This is a pattern that will match any Person object in WorkingMemory. The variable "likes" will be bound to the value of field "favouriteCheese" - i.e. personInstance.getFavouriteCheese(). If you have not already done so I suggest you read the documentation. -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Mithun Sent: 17 May 2007 07:14 To: rules-users(a)lists.jboss.org Subject: [rules-users] Drools basic questions. hi all, I am new to Drools, so i have some basic questions. I am sorry if my questions sound silly. Please help. 1. What does it mean when you prefix a variable with a dollar sign in a .drl file? If possible give a simple example please. 2. Please explain the following line of code: - Person( likes : favouriteCheese ) This is my understanding of the above code. - 'favouriteCheese' is a global variable which we are assingining to 'likes' and an object of type 'Person' is created by seding 'likes' as a paramerter to the constructor. Please correct me if i am wrong.
