All Implemented Interfaces:
Handler, HandlerContainer, org.eclipse.jetty.util.component.Container, org.eclipse.jetty.util.component.Destroyable, org.eclipse.jetty.util.component.Dumpable, org.eclipse.jetty.util.component.Dumpable.DumpableContainer, org.eclipse.jetty.util.component.LifeCycle
public class AsyncDelayHandler extends HandlerWrapper
A handler wrapper that provides the framework to asynchronously delay the handling of a request. While it uses standard servlet API for asynchronous servlets, it adjusts the dispatch type of the request so that it does not appear to be asynchronous during the delayed dispatch.

    Description
    protected void
    delayHandling(Request request, javax.servlet.AsyncContext context)
    Called to indicate that a requests handling is being delayed/ The implementation should arrange for context.dispatch() to be called when the request should be handled.
    protected void
    endHandling(Request request)
    Called to indicated the handling of the request is ending.
    void
    handle(String target, Request baseRequest, javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response)
    Handle a request.
    protected boolean
    startHandling(Request request, boolean restart)
    Called to indicate that a request has been presented for handling

    • handle

      public void handle(String target, Request baseRequest, javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) throws IOException, javax.servlet.ServletException
      Description copied from interface: Handler
      Handle a request.
      Specified by:
      handle in interface Handler
      Overrides:
      handle in class HandlerWrapper
      Parameters:
      target - The target of the request - either a URI or a name.
      baseRequest - The original unwrapped request object.
      request - The request either as the Request object or a wrapper of that request. The HttpConnection.getCurrentConnection().getHttpChannel().getRequest() method can be used access the Request object if required.
      response - The response as the Response object or a wrapper of that request. The HttpConnection.getCurrentConnection().getHttpChannel().getResponse() method can be used access the Response object if required.
      Throws:
      IOException - if unable to handle the request or response processing
      javax.servlet.ServletException - if unable to handle the request or response due to underlying servlet issue

    • startHandling

      protected boolean startHandling(Request request, boolean restart)
      Called to indicate that a request has been presented for handling
      Parameters:
      request - The request to handle
      restart - True if this request is being restarted after a delay
      Returns:
      True if the request should be handled now

    • delayHandling

      protected void delayHandling(Request request, javax.servlet.AsyncContext context)
      Called to indicate that a requests handling is being delayed/ The implementation should arrange for context.dispatch() to be called when the request should be handled. It may also set timeouts on the context.
      Parameters:
      request - The request to be delayed
      context - The AsyncContext of the delayed request

    • endHandling

      protected void endHandling(Request request)
      Called to indicated the handling of the request is ending. This is only the end of the current dispatch of the request and if the request is asynchronous, it may be handled again.
      Parameters:
      request - The request
