For example,
I have a HasMap
Map<String, Integer> map = new HashMap<String,Integer>();
map.put("amount",12);
My DRL is as follows :
when
$h : HashMap(this["amount"]!=null)
then
//something
or
when
$h : HashMap(this["amount"]> 10)
then
//something
i just want the object inserted inside the map to be used. I know this can
be done usind DRL but can this be achieved in GUVNOR ???

Hi Abhinay,
I was also expected the same and still struggling for the right answer . see
my older post

I would like to ask you that according to your first post you have created a
Hash Map.
Map<String, Integer> map = new HashMap<String,Integer>();
map.put("amount",12);
My DRL is as follows :
when
$h : HashMap(this["amount"]!=null)
then
//something
So did you created that in Guvnor or in hand coded drl file ? How Guvnor
will identified HashMap(this["amount"]!=null) statement without creating a
object of HashMap ?

Hello,
Using Guvnors "guided" features you cannot create constructs like this:
HashMap(this["amount"]!=null)
The only solution is to use a free-format DRL fragment (in either the
Guided Rule Editor, Guided Template Editor or Guided Decision Table).
With Guided Templates and Guided Decision Tables you could make the map key
a "template key" so values can be defined elsewhere:
HashMap(this["@{key}"]!=null)
An alternative to a free-format DRL fragment would be to define a DSL. DSLs
can be used in any of the foregoing editors.
With kind regards,
Mike

Hi Mike,
Thanks for the fast reply, I was aware of the free form DRL(I am using right
now in the same way).
Still, the template key is a new thing. Seems, it might come handy incase of
templates and decision table. Can you please provide some more inputs on its
usage with decision table or any pointers on its usage.
Regards,
Abhinay

Sure.
If you use a use a "BRL Fragment" in a decision table you can define a
column using the "Guided Rule Editor".
Template Keys added to field constraints (or free-format DRL) in the "BRL
Fragment" become columns in the decision table.
When adding a new column to the decision table click on the "Show Advanced
options" and you'll see "New BRL Condition column" and "New BRL
Action
column" (or something like that, I forget).
In essence "BRL Fragments" in decision tables allow decision tables to do
everything a Template can do.

Can i use a free form DRL in Web Guided Editor (Decision Table) ?
If yes, then how ?

Yes, add a "BRL Fragment" column, then add a "Free Format DRL".
Any values you want in the decision table should be entered as
"@{variable}" (ignoring the quotation marks if you don't need them).

Hi Aditi,
As already said by Stephens in your previous post Collections are Core Java
classes, you just have to import them in guvnor to use them. You can import
java.util.HashMap in your package edit section and make rules using them.
Then, you can insert HashMap(with values), as you insert class objects, in
your Ksession and use them.
Regards,
Abhinay
