Interface CometSupport<E extends AtmosphereResource>

All Known Implementing Classes:

AsynchronousProcessor, BlockingIOCometSupport, GlassFishv2CometSupport, GoogleAppEngineCometSupport, GrizzlyCometSupport, JBossWebCometSupport, Jetty7CometSupport, JettyCometSupport, Servlet30Support, TomcatCometSupport, WebLogicCometSupport

public interface CometSupport<E extends AtmosphereResource>

Atmosphere's supported WebServer must implement this interface in order to be auto detected by the AtmosphereServlet. If the AtmosphereServlet fail to detect the CometSupport, it will use a blocking thread approach to emulate Comet using the BlockingIOCometSupport. Framework designer or Atmosphere application developper can also add their own implementation of that class by referencing their class within the atmosphere.xml file:

 <<atmosphere-handler ... comet-support="your.class.name">
