How can I select planning-entities in the accumulate source-pattern based on a list of planning-variables?
9:59 a.m.
Hi,
I am kind of stuck in writing a rule :
I have PeopleMatch facts in working memory.
Each PeopleMatch has a number of persons: PeopleMatch().getPeople = List<Person>
I have planning-entities (Tasks) which have a planning-variable Person.
Now I would like to create a rule to loop over the PeopleMatch objects, gather all Tasks
for the people of this match and do some calculation with all tasks.
This is what I have for the moment:
rule "matchPeopleTasks"
when
$match : PeopleMatch()
$people : List() from $match .people
$match: Number( intValue < 0 )
from accumulate( $task : Task(handler == $people),
init( Matcher matcher = $match.getMatcher()),
action( matcher.addTask( $task ); ),
reverse( matcher.removeTask( $task ); ),
result( matcher.getMatch() ) );
then
...
end
The problem area is of course the "accumulate( $task : ProjectTask(handler ==
$people),"
How do I select all tasks in the accumulate function, based on a list of people?
Thanks,
Michiel

Assuming you want to deal with one PeopleMatch at a time:
when
$match : PeopleMatch( $people: people )
$match: Number( intValue < 0 )
from accumulate( $task : Task(handler memberOf $people), ...
I have some misgivings due to "intValue<0" and Matcher not being
assignment-compatible with java.lang.Number, but that's for you to
resolve.

Try to move 'from' in 'from accumulate'. Pay attention to "and"
in
'from accumulate'.
$match : PeopleMatch()
$match: Number( intValue < 0 )
from accumulate(
$people : List() from
$match.people and
$task : Task(handler == $people) ,
init( Matcher matcher =
$match.getMatcher()),
action( matcher.addTask( $task );
),
reverse( matcher.removeTask( $task
); ),
result( matcher.getMatch() ) );
