Enum Constant Details

START

public static final RequestEvent.Type START

The request processing has started. This event type is handled only by ApplicationEventListener.onRequest(RequestEvent) and will never be called for RequestEventListener.onEvent(RequestEvent).

MATCHING_START

public static final RequestEvent.Type MATCHING_START

The matching of the resource and resource method has started.

LOCATOR_MATCHED

public static final RequestEvent.Type LOCATOR_MATCHED

The sub resource locator method is found and it will be called. The locator method can be retrieved from RequestEvent.getUriInfo() by method ExtendedUriInfo.getMatchedResourceLocators().

SUBRESOURCE_LOCATED

public static final RequestEvent.Type SUBRESOURCE_LOCATED

The sub resource has been returned from sub resource locator, model was constructed, enhanced by model processor, validated and the matching is going to be performed on the sub resource. The sub resource can be retrieved from RequestEvent.getUriInfo() by method ExtendedUriInfo.getLocatorSubResources().

REQUEST_MATCHED

public static final RequestEvent.Type REQUEST_MATCHED

The matching has been finished and container request filters are going to be executed. The request filters can be retrieved from event by RequestEvent.getContainerRequestFilters() method. This method also determines end of the matching process and therefore the matching results can be retrieved using RequestEvent.getUriInfo().

REQUEST_FILTERED

public static final RequestEvent.Type REQUEST_FILTERED

Execution of container request filters has been finished.

RESOURCE_METHOD_START

public static final RequestEvent.Type RESOURCE_METHOD_START

Resource method is going to be executed. The resource method can be extracted from ExtendedUriInfo returned by RequestEvent.getUriInfo().

RESOURCE_METHOD_FINISHED

public static final RequestEvent.Type RESOURCE_METHOD_FINISHED

Resource method execution has finished. In the case of synchronous processing the response is not available yet. In the case of asynchronous processing the situation depends on the method design and it in some cases on race conditions. In asynchronous cases this event can be triggered even after the response is completely processed. Exactly defined, this event is triggered when the thread executing the resource method returns from the resource method.

RESP_FILTERS_START

public static final RequestEvent.Type RESP_FILTERS_START

Container response filters are going to be executed. In this point the response is already available and can be retrieved by RequestEvent.getContainerResponse(). The response filters can be retrieved by RequestEvent.getContainerResponseFilters().

This phase is executed in the regular response processing but might also been executed for processing on response mapped from exceptions by exception mappers. In this case the ON_EXCEPTION event type precedes this event.

RESP_FILTERS_FINISHED

public static final RequestEvent.Type RESP_FILTERS_FINISHED

Execution of Container response filters has finished.

This phase is executed in the regular response processing but might also been executed for processing on response mapped from exceptions by exception mappers. In this case the ON_EXCEPTION event type precedes this event.

ON_EXCEPTION

public static final RequestEvent.Type ON_EXCEPTION

Exception has been thrown during the request/response processing. This situation can occur in almost all phases of request processing and therefore there is no fixed order of events in which this event type can be triggered.

The origin of exception can be retrieved by RequestEvent.getExceptionCause(). This event type can be received even two types in the case when first exception is thrown during the standard request processing and the second one is thrown during the processing of the response mapped from the exception.

The exception thrown can be retrieved by RequestEvent.getException().

EXCEPTION_MAPPER_FOUND

public static final RequestEvent.Type EXCEPTION_MAPPER_FOUND

An ExceptionMapper is successfully found and it is going to be executed. The ExceptionMapper can be retrieved by RequestEvent.getExceptionMapper().

EXCEPTION_MAPPING_FINISHED

public static final RequestEvent.Type EXCEPTION_MAPPING_FINISHED

Exception mapping is finished. The result of exception mapping can be checked by RequestEvent.isResponseSuccessfullyMapped() which returns true when the exception mapping was successful. In this case the new response is available in the RequestEvent.getContainerResponse().

FINISHED

public static final RequestEvent.Type FINISHED

The request and response processing has finished. The result of request processing can be checked by RequestEvent.isSuccess() method. This method is called even when request processing fails and ends up with not handled exceptions.

Method Details

values

public static RequestEvent.Type[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static RequestEvent.Type valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
