Interface RequestEvent
- All Known Implementing Classes:
RequestEventImpl
public interface RequestEvent
An event informing about details of a request processing. The event is created by a Jersey runtime and
handled by
RequestEventListener (javadoc of listener describes how to register the listener for
particular request).
The event contains the RequestEvent.Type which distinguishes between types of event. There are various
properties in the event (accessible by getters) and some of them might be relevant only to specific event types.
Note that internal state of the event must be modified. Even the event is immutable it exposes objects
which might be mutable and the code of event listener must not change state of these objects.- Author:

Method Details
-
getType
RequestEvent.Type getType()Returns thetypeof this event.- Returns:
- Request event type.
-
getContainerRequest
ContainerRequest getContainerRequest()Get the container request. The container request is available for all event types. Returned request must not be modified by therequest event listener.- Returns:
- The non-null container request.
-
getContainerResponse
ContainerResponse getContainerResponse()Get the container response. The response is available only for certainevent types. The returned response might vary also on the event type. The getter returns always the latest response being processed. So, for example for eventRequestEvent.Type.EXCEPTION_MAPPING_FINISHEDevent type the method returns mapped response and not the original response created from execution of the resource method.- Returns:
- Latest response being processed or
nullif no response has been produced yet.
-
getException
Throwable getException()Get the latest exception, if any, thrown by the request and response processing. When this method returns not null value, the methodgetExceptionCause()returns the origin of the exception.- Returns:
- Exception thrown or
nullif no exception has been thrown.
-
getUriInfo
ExtendedUriInfo getUriInfo()Get theextended uri infoassociated with this request. This method returns null forRequestEvent.Type.STARTevent. The returnedExtendedUriInfocan be used to retrieve information relevant to many event types (especially event types describing the matching process).- Returns:
- Extended uri info or
nullif it is not available yet.
-
getExceptionMapper
ExceptionMapper<?> getExceptionMapper()Get theExceptionMapperthat was found and used during the exception mapping phase.- Returns:
- Exception mapper or
nullif no exception mapper was found or even needed.
-
getContainerRequestFilters
Iterable<ContainerRequestFilter> getContainerRequestFilters()Getcontainer request filtersused during the request filtering phase.- Returns:
- Container request filters or
nullif no filters were used yet.
-
getContainerResponseFilters
Iterable<ContainerResponseFilter> getContainerResponseFilters()Getcontainer response filtersused during the response filtering phase.- Returns:
- Container response filter or
nullif no filters were used yet.
-
isSuccess
boolean isSuccess()Returntrueif the request and response has been successfully processed. Response is successfully processed when the response code is smaller than 400 and response was successfully written. If the exception occurred but was mapped into a response with successful response code and written, this method returnstrue.- Returns:
- True if the response was successfully processed.
-
isResponseSuccessfullyMapped
boolean isResponseSuccessfullyMapped()Returnstrueif the response was successfully mapped from an exception byexception mappers. When exception mapping phase failed or when no exception was thrown at all the, the method returns false. This method is convenient when handling theRequestEvent.Type.EXCEPTION_MAPPING_FINISHEDevent type.- Returns:
- True if the exception occurred and it was successfully mapped into a response.
-
getExceptionCause
RequestEvent.ExceptionCause getExceptionCause()Get theexception cause. This method is relevant only in cases whengetException()returns non-null value (for example when handlingRequestEvent.Type.ON_EXCEPTION) event type.- Returns:
- Exception cause of the latest exception or
nullif no exception has occurred.
-
isResponseWritten
boolean isResponseWritten()Returnstrueif the response has been successfully written.trueis returned even for cases when the written response contains error response code.- Returns:
trueif the response was successfully written;falsewhen the response has not been written yet or when writing of response failed.
