Interface DistributionQueueDispatchingStrategy

All Known Implementing Classes:

AsyncDeliveryDispatchingStrategy, ErrorQueueDispatchingStrategy, MultipleQueueDispatchingStrategy, PriorityQueueDispatchingStrategy, SingleQueueDispatchingStrategy

public interface DistributionQueueDispatchingStrategy

a DistributionQueueDispatchingStrategy implements an algorithm for dispatching DistributionPackages among the available queues.

Usually a DistributionPackage will be dispatched to a single DistributionQueue but it would also be possible to dispatch the same package to multiple queues, resulting in obtaining multiple states (one for each queue) for a certain package.
