getNode

public Node getNode()
             throws ServiceException

Description copied from interface: Service.Slice

Access the node where this slice resides.

Specified by:

getNode in interface Service.Slice

Throws:

ServiceException - If some problems occur in retrieving the local node.

setNode

public void setNode(Node n)

serve

public VerticalCommand serve(HorizontalCommand cmd)

Try to serve an incoming horizontal command, routing it to a remote slice implementation.

Specified by:

serve in interface Service.Slice

Parameters:

cmd - The command to serve, possibly through the network.

Returns:

A vertical command, that will be processed by the incoming filter chain of the receiving node. If null is returned, no filter/sink processing will happen. This feature can be used to decouple incoming horizontal interaction patterns from vertical incoming commands (e.g. no incoming vertical command is generated until a required set of horizontal commands has been received).
