Passing Collection of objects and multiple arguments
2004-01-12 08:05
Hi, We prefer to use mandarax as the rule engine in our Hospital Information System. To begin with, we have some fundamnetal doubts regarding the implemetation. We expect your advice for the follwing doubts. 1)Can we pass a group of objects in a collection to the query? Say a collection of Customer objects . We have situations similar to, hundreds of customer instances which go through the rule checks and only valid customers need to be returned ( by querying the knowledgebase ) . So here a collection of customers are passed and a collection of valid customers (may be a Collection of valid discounts ) returned. 2)How can we pass multiple arguments in to the inference engine at query time? Say I want to pass both customer object, and his turn_over_object. Is there any limitation to the number of arguments? Can we pass an object array? And if so, what should be their order? 3)To access the member variables of the passing object we need to create Separate JFunctions for each member. This is a tedious process. Is there any other simple alternative? We want to access the values just by specifying the Class name and its member variables name. Thanks , Sabarinathan.
