Sorry, where should we look in the manual for this?

   Do you mean like:

There is a client
   - which is adult
   - whose wife is adult

    Mapped to:

Client( age > 17, spouse.age > 17 )

    Take a look at the manual and check for the "-" special character.

Hi All,

I am new to Drools - my company is evaluating it for use in a project. We
are doing a proof of concept, and we are developing a DSL. One of our DSL
expressions is

"client is an adult"

which is defined as

Client(age > 17)

The problem we have is that there are many different types of people in our
system that we would like to test for adulthood. For example, we have the
client's spouse (Client.spouse), and the clients children (Client.children),
who we also want to test for adulthood. Do we need to make a different DSL
expression for each case, or is there a way to "genericize" the DSL
expression so it could be used for any person?

TIA,

-Hans
