Re: [rules-users] Identifiers on LHS
Sorry for not explaining it before, Mauricio. My intent is to abstract the
attribute's setting of a class. I'll try to explain the context:
On a defined class i've got certain fields which I tagged with
annotations. I want to automate the setting of these fields from certain
objects matched by a rule, the matching between the class fields and the
objects would be the identifiers. The field annotation holds the expected
identifier to match. Thus, a general method would be capable to set the
fields of any class just passing to it the class fields and the identifiers
metadata.
What i've been developing is related with situation detection. The 'class' I
refer above is a situation type and the attributes are roles that an entity
can play in a situation. Each situation type has a rule that defines when it
is active and must instantiate a new situation and set the participant
entities.
I''ll talk more about what i'm working on as soon as i get time to write.
Thanks for the help,

You can get metadata using the kcontext variable but I'm not sure
if you
can get the information about the identifiers.
Can you describe what are you looking to achieve? because the rule is fixed
and the identifiers as well. Why do you want to do reflection like stuff in
the RHS? I'm just curious..
Cheers
