io.netty.resolver.dns

Class NameServerComparator

java.lang.Object

io.netty.resolver.dns.NameServerComparator

All Implemented Interfaces:

Serializable, Comparator<InetSocketAddress>

public final class NameServerComparator
extends Object
implements Comparator<InetSocketAddress>, Serializable

Special Comparator implementation to sort the nameservers to use when follow redirects. This implementation follows all the semantics listed in the Comparator apidocs with the limitation that InetSocketAddress.equals(Object) will not result in the same return value as compare(InetSocketAddress, InetSocketAddress). This is completely fine as this should only be used to sort Lists.
