Re: [rules-users] How to iterate ArrayList object

I have a Message Object which has a Attribute Object which has a ArrayList of AttributeParams Objects. How can I iterate through the ArrayList to get to a perticular AttributeParans Object in the drl file. The java representation of these Objects are as Follows Class Message { private Attributes attributes; } Class Attributes { private ArrayList<AttributeParams> attributeParams; } Class AttributeParsms { private String name; } This is my drl file, when m : Message( myAttributes : attributes) then System.out.println(myAttributes); System.out.println(myAttributes.getAttributeParams()); System.out.println( myMessage ); when I fire my rule, this is the output I am getting. com.sample.Attributes@39c639c6 [com.sample.AttributeParams@39a639a6, com.sample.AttributeParams@39ac39ac] From the result we can see that we have two Attribute objects in the ArrayList. How can I iterate through the ArrayList to get a perticular AttributeParams object This is my drl file, when m : Message( myAttributes : attributes) then System.out.println(myAttributes); System.out.println(myAttributes.getAttributeParams()); System.out.println( myMessage ); when I fire my rule, this is the output I am getting. com.sample.Attributes@39c639c6 [com.sample.AttributeParams@39a639a6, com.sample.AttributeParams@39ac39ac] From the result we can see that we have two Attribute objects in the ArrayList.
