Suppose my client code initially asserts two Facts into WorkingMemory instance: one Source object and one TargetOne object. As the rules get applied, some of the rules may assert additional Target facts into WM. How can I retrieve all of the Target facts (however many were created) from the WorkingMemory after fireAllRules() method was called (regardless of how many Target objects were created as a result)?! I will not know the concrete type of the target object types that were asserted into WM instance, as they can be as many as 7 class sub-types (TargetOne, TargetTwo, TargetThree), though they will all share a common super-class (com.mypackage.Target). Can someone show an example on how to fetch the resulting Target objects after fireAllRules() is called and filter out the Target objects?
