Class WebsocketAddr

java.lang.Object
com.tccc.kos.commons.util.net.WebsocketAddr
public class WebsocketAddr extends Object
Data class encapsulating the pieces that make up a KOS websocket network address. These KOS addresses are used within the routed websocket mesh network, and have the following structure: 
  zone:routerId:clientId
Each of the three pieces are:
  • zone -- identifies a cluster of nodes, where all routers in the same zone know about each other, can route between them, and can typically recover if there's a failure.
  • routerId -- is a unique (within its zone) identifier for a router. Exactly one router runs on every node.
  • clientId -- is any non-router piece of software that makes a websocket connection to a KOS router. This is typically a browser, but can be anything that can open a websocket. The clientId for the router itself is always zero.

Data Fields

 
  private String zone;      // zone of the address
  private String routerId;  // router within the zone
  private String clientId;  // client attached to the router (or 0 for the router itself)

Examples

Constructors

 
  // Both of these constructor calls create the same network address:
  new WebsocketAddr("Zone1", "Router7", "Client12");
  new WebsocketAddr("Zone1:Router7:Client12");
