Class TurbineStreamServlet

java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

com.netflix.turbine.streaming.servlet.TurbineStreamServlet

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class TurbineStreamServlet
extends javax.servlet.http.HttpServlet

Stream responses to browser according to Server-Side Event spec.

The servlet first attempts to find the ClusterMonitor for the specified cluster param. Once this is found it creates the TurbineStreamingConnection and then gives it it's own StreamingDataHandler to handle events from the streaming connection. All data written to the StreamingHandler is then sent out over the http connection using the Server-Side Event spec.
