I have a rule that filters an ArrayList based on dynamic filtering
conditions, for example this list can be a set of documents and the filter
can be a user property which is required later for document filling (e.g.
private name).
This is fairly strait forward, where I can perform something of the sort:
Rule "test filter"
When
$cm: ConditionMatrix(),
$document: ArrayList() from collect ( Document
(user.isPrivateName == $cm.isPrivateName) )
Then
//do something
End
Now comes my question: I have a different rule that holds a different set of
filter requirements that works on Document object.
For example
Rule "test filter 2"
When
$cm: ConditionMatrix(),
$document: ArrayList() from collect ( Document
(Payment.isLegal == $cm.isLegal) )
Then
//do something
End
Is there any way to combine them both?
Thanks

Not sure of what you exactly ...
If you want to combine tests, you can write this :
Rule "test filter"
When
$cm: ConditionMatrix()
$document: ArrayList() from collect ( Document
(user.isPrivateName == $cm.isPrivateName, Payment.isLegal == $cm.isLegal) )
Then
//do something
End
If you want to make the filter more dynamic and write only one "collect"
rule, I don't see any out-of-the-box method.
You can add a method in ConditionMatrix that accepts a Document and
write this rule :
Rule "test filter"
When
$cm: ConditionMatrix()
$document: ArrayList() from collect ( Document
(eval($cm.accept(this))) )
Then
//do something
End
Of course you have to implement the "accept" method in Java (and you can
then do several sub-classes for you filters)

Just for the heck of it, here's two more ways for "comibining" those two
rules. (Gee, what a vague specification!)
# straightforwardly doing both in one
rule comb1
when
$cm: ConditionMatrix()
$docs1: ArrayList() from collect( Document( ... ) )
$docs2: ArrayList() from collect( Document( ... ) )
then ... end
# abstraction
rule comb2
when
$cm: ConditionMatrix()
$filter: Filter()
$docs: ArrayList() from collect( $d: Document() eval( $filter.pass( $cm,
$d ) ) )
then ... end

Thanks for the reply, I think I was a bit vague with my question (my
apologies on this) I will try to elaborate further
I have several set of rules that filter, each filters a different set of
conditions (e.g. User, Date, Country.).
I would like to construct rules that based on conditions in the
ConditionMatrix (in my example) I would like to set a specific rule set.
A wishful thinking approach would be something like:
Following are 2 filter rules
Rule "filter user"
When
$cm: ConditionMatrix(),
$document: ArrayList() from collect ( Document
(user.isPrivateName == $cm.user.isPrivateName) )
Then
End
Rule "filter date"
When
$cm: ConditionMatrix(),
$document: ArrayList() from collect ( Document
(date.isLegal == $cm.date.isLegal) )
Then
//do something
End
The actual rule that utilized them would like :
Rule "I am happy" extends "filter date"
When
$cm: ConditionMatrix(),
Then
//Do something
End
And a second rule can look like: (note that even if I can extend two rules
then there is a conflict on $ document)
Rule "I am sad" extends "filter date", "filter user"
When
$cm: ConditionMatrix(),
Then
//Do something
End
Hope this clearer now.
Thanks

It's pointless to discuss (non-existent) technical solutions without knowing
what the problem is.
So far:
- a set of Document objects should be selected for processing.
- selection can be based on any of the Document properties
- the actual property value is contained in an object ConditionMatrix
Why should processing of documents selected according to "privateName"
combined with those selected according to "legal"?
Otherwise, what is to be gained by "combining"?
