Hi all,

Is there a way using the ‘from’ constraint to get the values of a map(the implementations of java.lang.Map eg HashMap, TreeMap, etc) into a constraint parameter, and if so can someone please give an example. Below is the way I’ve been trying, without success, to get a value based on a key.

import my.package.MyFact

import java.util.Map.Entry

rule “Find with map”

                when

                                $fact : MyFact($paramMap : paramMap)

                                $myValue : Entry(key == “mykey1”) from $paramMap

                Then

// Sudo code…

                                <use $myValue.getValue()>

end
