Class EventSourceTransport

java.lang.Object
  io.netty.channel.ChannelHandlerAdapter
      org.jboss.aerogear.io.netty.handler.codec.sockjs.transport.EventSourceTransport

All Implemented Interfaces:

io.netty.channel.ChannelHandler

public class EventSourceTransport
extends io.netty.channel.ChannelHandlerAdapter

EventSource transport is an streaming transport in that is maintains a persistent connection from the server to the client over which the server can send messages. This is often refered to a Server Side Event (SSE) and the client side. The response for opening such a unidirection channel is done with a simple plain response with a 'Content-Type' of 'text/event-stream'. Subsequent http chunks will contain data that the server whishes to send to the client.
