Check if a List <String> field contains any of the comma separated values

[AV]

Hey folks,

I have a scenario (as described below) where I need to check if a list contains any one of the values but I am trying to figure out a way to pass it as comma separated values.

Scenario:

We have a field called code which was of type String, and say the rule requirement is - If code is Code1 or Code2 or Code3, then perform some actions.

We were able check for all the three codes - Code1, Code2 and Code3 in a same row in a decision table or in a guided rule too by putting comma separated values.

Now, as per the new requirement we can have multiple codes in the request and hence we had to change the data type of code to List<String>;

Issue:

To check for each code, I have to put a new row in a guided decision table or an OR condition in a guided rule like 

code contains Code1 

or code contains Code2 

or code contains Code3

which earlier I was able to put as,

code is contained in the (comma separated) list Code1, Code2, Code3.

Is there a way to check if the code (which is a List<String> now) contains any of the comma separated values?

Thanks,

AV

In DRL terms you should be able to do something like:

YourFact( $codes : codes )

String( this in ("code1", "code2" ) ) from $codes

This can be created with both the Guided Rule Editor and Guided Decision Table Editor (using Free From Lines)

Hi, 

 you can use matches with regular expression to find with for key word combination to iterate list of string.

Yes but I wanted to avoid using any DRL/Code in the table for this field. Would be more readable to business users if I just had comma separated values in a cell and it looked if any of the comma separated values exist in the collection its checked against.

Can you put an example on how the data would look like in the decision table.

Would appreciate if you can share some more info on this like a tutorial etc. in case you have/find a link for the same.

Thanks,
