We need to improve docs on that, as it is only mentioned briefly:

https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-expert/html/ch07.html#d0e3206

      The @key will do it for you:

declare Person
    name : String
    ssn : BigDecimal @key
    age : int
end
  
     Wanna write a quick patch for the docs emphasizing the use of it?

     Thanks,

declare Person

  name : String

  ssn: BigDecimal

  age : int

end

 

 

Is there a way to define what field/s identify a Person?

 

In the example above I would like to define ssn as the unique indentifier for person, so person1 == person2 if person1.ssn == person2.ssn.

 

In this case equals would use only the field ssn to determine if 2 person objects are equal.

The hashcode should also be based only on the ssn field.

 

I want to use Person with assertBehaviour equality…

 

Thanks
