Interface AsyncSupport<E extends AtmosphereResource>

All Known Implementing Classes:

AsynchronousProcessor, BlockingIOCometSupport, GlassFishv2CometSupport, GlassFishWebSocketSupport, Grizzly2CometSupport, Grizzly2WebSocketSupport, GrizzlyCometSupport, JBossWebCometSupport, Jetty7CometSupport, JettyAsyncSupportWithWebSocket, JettyCometSupport, JettyServlet30AsyncSupportWithWebSocket, NettyCometSupport, Servlet30CometSupport, Tomcat7AsyncSupportWithWebSocket, Tomcat7BIOSupportWithWebSocket, Tomcat7CometSupport, Tomcat7Servlet30SupportWithWebSocket, TomcatCometSupport

public interface AsyncSupport<E extends AtmosphereResource>

Atmosphere's supported WebServer must implement this interface in order to be auto detected by the AtmosphereFramework. If the AtmosphereFramework fail to detect the AsyncSupport, it will use a blocking thread approach to emulate Comet using the BlockingIOCometSupport.

Framework designer or Atmosphere application developer 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">
