I have a n object which has a method which returns java.util.Map . Is it easy to implement a rule which calls the gettter method on this object for the map and get the value for a specified key and check condition on that value ? Example class MyObject { private Map properties; public Map getProperties(){ return properties; } public void setProperties(Map aMap){ this.properties=aMap; } Now the rule I need is MyObject aObject= new MyObject(); return ( aObject.getPorperties().get("price").toString.equals("aproperty")) } Is this possible to write in a drl file and is this a good approach also is using eval in a drl file is not a good solution ie it has any problems ?
