All Implemented Interfaces:

Comparable<Endpoint>
```
public final class Endpoint
extends Object
implements Comparable<Endpoint>
```
A remote endpoint that refers to a single host or a group of multiple hosts.
A host endpoint has host(), optional ipAddr() and optional port(). It can be represented as "<host>" or "<host>:<port>" in the authority part of a URI. It can have an IP address if the host name has been resolved and thus there's no need to query a DNS server.
A group endpoint has groupName() and it can be represented as "group:<groupName>" in the authority part of a URI. It can be resolved into a host endpoint with resolve(ClientRequestContext).

  - parse
```
public static Endpoint parse(String authority)
```
    Parse the authority part of a URI. The authority part may have one of the following formats:
    
    "group:<groupName>" for a group endpoint
    
    "<host>:<port>" for a host endpoint
    
    "<host>" for a host endpoint with no port number specified
    
    An IPv4 or IPv6 address can be specified in lieu of a host name, e.g. "127.0.0.1:8080" and "[::1]:8080".

```
public static Endpoint ofGroup(String name)
```
    Creates a new group Endpoint.
