Re: [rules-users] Is it possible to Iteriate over a list of string values ?
Hi all,
The way I understand your question, you want to evaluate some string value
to a list of Strings, and insert an "alarm" in the form of a new object to
notify that these values are present.
This is possible. Insert a String into working memory, then call the
following rule:
#Testing rule
rule "test"
when
$vals: String(this in ("help","support","assist"))
not Fact(value == $vals )
then
insert ( new Fact ( $vals ) );
System.out.println("This WORKS!");
end
The rule checks for a String in working memory, and evaluates its contents (
this in ( list ) ) . If a Fact with the corresponding value hasn"t been
inserted yet, it will be inserted at runtime.

Hello all,
In one of my use cases, I need to insert a variable collections of facts
into working memory in order to be able to test for those values later :
So I was wondering if there's a way to do something like this
when
$vals : String() from [ "A 12345", "B 45678", "C
8695" ]
then
insert ( new Fact ( $vals ) );
With the intention that the rule will fire 3 times and insert the 3 new
facts with the values " A 12345" and "B 45678" and "C
8695".
Is this possible using rules or do I have to resort to using functions.
The problem I'm trying to overcome is to see if there's a way to get the
"A 12345", "B 45678", "C 8695" from a single cell of a
spreadsheet.
Thanks in advance,
G
