Class BlockingIOCometSupport

java.lang.Object
  org.atmosphere.cpr.AsynchronousProcessor
      org.atmosphere.container.BlockingIOCometSupport

All Implemented Interfaces:

CometSupport<AtmosphereResourceImpl>

Direct Known Subclasses:

GoogleAppEngineCometSupport

public class BlockingIOCometSupport
extends AsynchronousProcessor
implements CometSupport<AtmosphereResourceImpl>

This class gets used when the AtmosphereServlet fails to autodetect the Servlet Container we are running on. This CometSupport implementation uses a blocking approach, meaning the request thread will be blocked until another Thread invoke the Broadcaster.broadcast(java.lang.Object)
