org.jboss.solder.servlet.event
Class ServletEventBridgeFilter

java.lang.Object
  org.jboss.solder.beanManager.BeanManagerAware
      org.jboss.solder.servlet.event.AbstractServletEventBridge
          org.jboss.solder.servlet.event.ServletEventBridgeFilter

All Implemented Interfaces:

javax.servlet.Filter

public class ServletEventBridgeFilter
extends AbstractServletEventBridge
implements javax.servlet.Filter

Propagates the ServletResponse lifecycle events to the CDI event bus, complementing the ServletEventBridgeListener, which handles the other lifecycle events.

This filter is auto-registered in Servlet 3.0 environments. If CDI injection is available into filters, the BeanManager will be accessible to this instance as an injected resource. Otherwise, the BeanManager will be looked up using the BeanManager provider service.

The internal events are fired to ensure that the setup and tear down routines happen around the main events. The event strategy is used to jump from a Servlet component which may not be managed by CDI to an observe we know to be a managed bean.
