Examples of org.drools.WorkingMemory.iterateObjects()

org.drools.WorkingMemory.iterateObjects()
Returns an Iterator for the Objects in the Working Memory. This Iterator is not thread safe. This means that any working memory actions during iteration may invalidate the iterator. @return the Iterator
