Re: [rules-users] Matching strings in two arrays

You could define a new operator (similar to "contains" or "memberOf")

See my home page for a full recipe: http://members.inode.at/w.laun/
The code given there is for both sides being java.util.Collection.
Handling
of
arrays could be added. But you should also consider providing the sets for
the rules as static auxiliary facts.

Thanks for the sample code. I also explored other operators in the jboss
code base and now have a fairly good understanding of it.
In my use case I have a fixed set of values in the right side of of the
operator. Only the left side changes as input fact --
when
MyContext(inputSetOfStings subsetOf ("StringVal1", "StringVal2",
"StringVal3", "StringVal4"))
How do I construct this rhs of the operator such that it is taken as a
collection when the rule is compiled?
Thanks
Kumar
