[rules-users] Literal representation for value objects

Hi, In my application we use few value objects. For example, Dates, Quantities and Durations. These objects are immutable and have some behavior. For example, comparing two quantities may involve quantity-conversion computations (“2 foot” < “3 meter”). In drools documentation I found an interesting example (section 6.5.2.1.1.3.2. Literal Restrictions, example 6.20): Cheese( bestBefore < “27-Oct-2007”) How Does the parser knows to create a Date object from that String? Does Date has a ‘specialized’ behavior in drools? Is it possible to ‘plugin’ similar behavior for my value classes? How? I’d like to achieve the following functionality: Person(height < “2-meter”) Thanks, David -- View this message in context: http://www.nabble.com/Literal-representation-for-value-objects-tp22397729...
