AlpnOpenListener (Undertow 2.0.30.Final API)

java.lang.Object
- io.undertow.server.protocol.http.AlpnOpenListener

All Implemented Interfaces:

OpenListener, EventListener, org.xnio.ChannelListener<org.xnio.StreamConnection>
```
public class AlpnOpenListener
extends Object
implements org.xnio.ChannelListener<org.xnio.StreamConnection>, OpenListener
```
Open listener adaptor for ALPN connections
Not a proper open listener as such, but more a mechanism for selecting between them.
