Re: [rules-users] Accumulate / collect
Hi Wolfgang, hi Estaban,
Many thanks for your insights!
I'll stick to a custom accumulate function since it is more consice than
the init/action/result approach.
And since I am using Drools 5.1.1, I'll create functions named
collectList and collectSet to be "future proof" :-)
Best regards,
Bruno.

You already have 2 accumulate functions to do what you need:
* collectList
* collectSet
So, your rule will look like this:
$countries : HashSet(empty == false) from accumulate (City($name
matches "X.*", $country : country), collectSet($country))
Best Regards,
