Method Detail

find

public StreamEvent find(StateEvent matchingEvent,
                        IndexedEventHolder indexedEventHolder,
                        StreamEventCloner storeEventCloner)

Description copied from interface: CollectionExecutor

Find the Events matching to the condition, used on the primary call
