All Implemented Interfaces:

com.google.common.util.concurrent.Service, SystemParametersProducer, Link, LinkActionProvider, ParameterDataLink, TcDataLink, TmPacketDataLink

public class YgwNodeLink
extends AbstractTcTmParamLink

Corresponds to a Node in the Yamcs Gateway or to a sub-link (in the gateway each node can have zero or more sub-links)

Each sub-link has an id and the node itself functions as a link with id 0
