Examples of javax.ws.rs.container.AsyncResponse.cancel()

javax.ws.rs.container.AsyncResponse.cancel()

Cancel the suspended request processing.

When a request processing is cancelled using this method, the JAX-RS implementation MUST indicate to the client that the request processing has been cancelled by sending back a {@link javax.ws.rs.core.Response.Status#SERVICE_UNAVAILABLE HTTP 503 (Service unavailable)}error response.

Invoking a {@code cancel(...)} method multiple times to cancel request processing has the sameeffect as canceling the request processing only once. Invoking a {@code cancel(...)} method onan asynchronous response instance that has already been resumed has no effect and the method call is ignored while returning {@code true}.

@return {@code true} if the request processing has been cancelled, returns {@code false} in casethe request processing is not {@link #isSuspended() suspended} and could not be cancelledand is not {@link #isCancelled() cancelled} already. @see #cancel(int) @see #cancel(java.util.Date)

      int retryAfter = Integer.parseInt(sRetryAfter);
      boolean b = response.cancel(retryAfter);
      // Invoking a cancel(...) method multiple times to cancel request
      // processing has the same effect as canceling the request processing
      // only once.
      b &= response.cancel(retryAfter * 2);
      addResponse(response, stage);
      return b ? TRUE : FALSE;
   }
