dhtBroadcastCallback

public void dhtBroadcastCallback(DKSObject value)

Description copied from interface: DKSDHTCallback

Receive a broadcast message

Specified by:

dhtBroadcastCallback in interface DKSDHTCallback

dhtRouteCallback

public DKSMessage dhtRouteCallback(long identifier,
                                   DKSMessage msg)

Description copied from interface: DKSDHTCallback

The callback is called at the responsible node when a route() message reaches its destination and the message is not handled at a lower abstraction layer. It receives a DKSMessage, and returns a possibly new DKSMessage INVARIANT: the implementor of this method SHOULD immediately return, as otherwise the underlying DKSNode cannot process new messagesl, and consequently the method cannot recursively call other methods in the DKSInterface as the DKSNode will not be able to receive response messages. Consider using routeAsync() in DKSInterface.

Specified by:

dhtRouteCallback in interface DKSDHTCallback

Parameters:

identifier - long, the identifier searched for in route, maybe not interesting for the app in many cases.

Returns:

DKSObject the payload to be routed back or null if the message is unhandled

dhtRouteCallbackAsync

public void dhtRouteCallbackAsync(long identifier,
                                  DKSMessage msg)

Description copied from interface: DKSDHTCallback

The callback is called at the responsible node when a route() message reaches its destination and the message is not handled at a lower abstraction layer. It receives a DKSMessage

Specified by:

dhtRouteCallbackAsync in interface DKSDHTCallback

Parameters:

identifier - long, the identifier searched for in route, maybe not interesting for the app in many cases.

msg - DKSObject, the actual payload sent by the source
