Class RedirectUponFailurePolicy

java.lang.Object
  ch.elca.el4j.services.remoting.protocol.loadbalancing.policy.AbstractPolicy
      ch.elca.el4j.services.remoting.protocol.loadbalancing.policy.RedirectUponFailurePolicy

public class RedirectUponFailurePolicy
extends AbstractPolicy

This class defines the following load-balancing property: The protocols are returned in a round-robin way, but the currently used protocol only changes if a failure has been notified about it. However, no protocol is removed from the list of protocols, and failed protocols will eventually be returned again by nextProtocol.
