All Implemented Interfaces:

NameResolver<InetAddress>, Closeable, AutoCloseable

public class RoundRobinInetAddressResolver
extends InetNameResolver

A NameResolver that resolves InetAddress and force Round Robin by choosing a single address randomly in SimpleNameResolver.resolve(String) and SimpleNameResolver.resolve(String, Promise) if multiple are returned by the NameResolver. Use InetNameResolver.asAddressResolver() to create a InetSocketAddress resolver
