[temp temp]

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 ?
  Thanks 
  Miro
