Examples of reactor.net.Reconnect

reactor.net.Reconnect
Implementations of this interface will be instantiated by a {@link reactor.function.Supplier} to provide informationto the {@link reactor.net.tcp.TcpClient} whether or not to attempt to reconnect a broken connection.
The {@link #reconnect(java.net.InetSocketAddress,int)} method will be invoked, passing the currently-connectedaddress and the number of times a reconnection has been attempted on this connection. If the client is to reconnect to a different host, then provide that different address in the return value. If you don't want to try and reconnect at all, simply return {@code null}. @author Jon Brisbin
