[rules-users] Comparing names

[Ian Spence]

Hello all,

I am new to Drools…



I have a scenario



Each fact object will have the structure:



Title

   Proprietor Group

      Proprietor Name



E.g.

            2100-100

                        J2 ½ share

                                    SMITH, JOHN

                                    JONES, FRED

                        T ½ share

                                    BROWN, CHARLIE

            2100-101

                        J2 ½ share

                                    BROWN, CHARLIE

                                    JONES, FRED

                        T ½ share

                                    SMITH, JOHN

            2100-102

                        T ½ share

                                    BROWN, CHARLIE

                        J2 ½ share

                                    JONES, FRED

                                    SMITH, JOHN



The group names and the proprietor names must be the same across each
Title.  The scenario above is a valid case. A failed case would result for
Title 2100-100 if we add an extra Proprietor name e.g. WHITE, MARY.



I anticipate having one rule to cater for this.  I am hedging towards the
‘collect’ operator but cannot get a clear picture on how to implement it.
