[rules-users] Fetching Facts from WM...

[jdepaul]

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? 

Thanks in advance - 
James
