Re: [rules-users] Map using from constraint

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 *Paul Ryan* *Software Architect Product Engineering** **InfoTrust Group, Inc.* Logo FINAL 1-30-08_scaled 500 Discovery Parkway, Suite 200 Superior, CO 80027 *Office* (303) 627-6528 *Fax* (303) 666-6711 *Email* pryan(a)infotrustgroup.com <mailto:pryan@infotrustgroup.com> *WEB* www.infotrustgroup.com <http://www.infotrustgroup.com/> / / /This e-mail and all information included herein do not constitute a legal agreement accorded by INFOTRUST GROUP and its affiliates and subsidiaries.
