Class RoundRobinInetAddressResolver

java.lang.Object

io.netty.resolver.SimpleNameResolver<java.net.InetAddress>

io.netty.resolver.InetNameResolver

io.netty.resolver.RoundRobinInetAddressResolver

All Implemented Interfaces:

NameResolver<java.net.InetAddress>, java.io.Closeable, java.lang.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
