Method Detail

• onComplete

  void onComplete(AsyncEvent event)
           throws java.io.IOException

  Notifies this AsyncListener that an asynchronous operation has been completed.

  The AsyncContext corresponding to the asynchronous operation that has been completed may be obtained by calling getAsyncContext on the given event.

  In addition, if this AsyncListener had been registered via a call to AsyncContext.addListener(AsyncListener, ServletRequest, ServletResponse), the supplied ServletRequest and ServletResponse objects may be retrieved by calling getSuppliedRequest and getSuppliedResponse, respectively, on the given event.

  Parameters:

  event - the AsyncEvent indicating that an asynchronous operation has been completed

  Throws:

  java.io.IOException - if an I/O related error has occurred during the processing of the given AsyncEvent

• onTimeout

  void onTimeout(AsyncEvent event)
          throws java.io.IOException

  Notifies this AsyncListener that an asynchronous operation has timed out.

  The AsyncContext corresponding to the asynchronous operation that has timed out may be obtained by calling getAsyncContext on the given event.

  In addition, if this AsyncListener had been registered via a call to AsyncContext.addListener(AsyncListener, ServletRequest, ServletResponse), the supplied ServletRequest and ServletResponse objects may be retrieved by calling getSuppliedRequest and getSuppliedResponse, respectively, on the given event.

  Parameters:

  event - the AsyncEvent indicating that an asynchronous operation has timed out

  Throws:

  java.io.IOException - if an I/O related error has occurred during the processing of the given AsyncEvent

• onError

  void onError(AsyncEvent event)
        throws java.io.IOException

  Notifies this AsyncListener that an asynchronous operation has failed to complete.

  The AsyncContext corresponding to the asynchronous operation that failed to complete may be obtained by calling getAsyncContext on the given event.

  In addition, if this AsyncListener had been registered via a call to AsyncContext.addListener(AsyncListener, ServletRequest, ServletResponse), the supplied ServletRequest and ServletResponse objects may be retrieved by calling getSuppliedRequest and getSuppliedResponse, respectively, on the given event.

  Parameters:

  event - the AsyncEvent indicating that an asynchronous operation has failed to complete

  Throws:

  java.io.IOException - if an I/O related error has occurred during the processing of the given AsyncEvent

• onStartAsync

  void onStartAsync(AsyncEvent event)
             throws java.io.IOException

  Notifies this AsyncListener that a new asynchronous cycle is being initiated via a call to one of the ServletRequest.startAsync() methods.

  The AsyncContext corresponding to the asynchronous operation that is being reinitialized may be obtained by calling getAsyncContext on the given event.

  In addition, if this AsyncListener had been registered via a call to AsyncContext.addListener(AsyncListener, ServletRequest, ServletResponse), the supplied ServletRequest and ServletResponse objects may be retrieved by calling getSuppliedRequest and getSuppliedResponse, respectively, on the given event.

  This AsyncListener will not receive any events related to the new asynchronous cycle unless it registers itself (via a call to AsyncContext.addListener(javax.servlet.AsyncListener)) with the AsyncContext that is delivered as part of the given AsyncEvent.

  Parameters:

  event - the AsyncEvent indicating that a new asynchronous cycle is being initiated

  Throws:

  java.io.IOException - if an I/O related error has occurred during the processing of the given AsyncEvent
