I'm new to Drools, and really need to know if the engine can support lazy loading of fact objects using declared types. Maybe I'm coming at this wrong, but I want to avoid retrieval for attributes that are not referenced during rule execution, and only retrieve attributes as the first time they are used in the current evaluation as some objects could come from database or other systems. In coding terms: if x==false && y==true then, I should never need to retrieve 'y'. In addition, I cannot use pojo's at design time, as my data structures are defined by the business and loaded at runtime, so I tried looking at declared types, but I'm not certain these will support lazy loading.
