Package io.undertow.server.protocol.http

Class AlpnOpenListener

java.lang.Object

io.undertow.server.protocol.http.AlpnOpenListener

All Implemented Interfaces:

OpenListener, java.util.EventListener, org.xnio.ChannelListener<org.xnio.StreamConnection>

public class AlpnOpenListener
extends java.lang.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.
