Class UpgradeConnection

java.lang.Object

org.eclipse.jetty.io.AbstractConnection

org.eclipse.jetty.websocket.client.io.UpgradeConnection

All Implemented Interfaces:

Closeable, AutoCloseable, Connection, Connection.UpgradeFrom

public class UpgradeConnection
extends AbstractConnection
implements Connection.UpgradeFrom

This is the initial connection handling that exists immediately after physical connection is established to destination server.

Eventually, upon successful Upgrade request/response, this connection swaps itself out for the WebSocektClientConnection handler.
