Class LinkFactory
It is perfectly reasonable for a user to create a Link to another Node without utilising the normal connection methods. This class is therefore made public to allow such an occurrence.
Example, using TCP/IP
TCPIPNodeAddress address = new TCPIPNodeAddress("192.168.1.100", 5000);
Link link = LinkFactory.getLink(address);
The getLink method will either return an existing Link if one exists, or it shall create a new one if necessary.
Using this method allows quick creation of channels / barrier on a remote Node without going through the normal name servers. For example:
NetChannelLocation loc = new NetChannelLocation(link.getRemoteNodeID(), 100);
NetChannelOutput out = NetChannelEnd.one2net(loc);
This method is generally considered faster than using the CNS, or creating channels just using the address and VCN. It does require the user to know the address and channel number that is to be connected too.
