public class RecipientListProcessor
extends MulticastProcessor

Implements a dynamic Recipient List pattern where the list of actual endpoints to send a message exchange to are dependent on some dynamic expression.

This implementation is a specialized MulticastProcessor which is based on recipient lists. This implementation have to handle the fact the processors is not known at design time but evaluated at runtime from the dynamic recipient list. Therefore this implementation have to at runtime lookup endpoints and create producers which should act as the processors for the multicast processors which runs under the hood. Also this implementation supports the asynchronous routing engine which makes the code more trickier.
