Method Detail

findHandlers

public <T> void findHandlers(@Observes
                    javax.enterprise.inject.spi.ProcessBean<?> pmb,
                    javax.enterprise.inject.spi.BeanManager bm)

Listener to ProcessBean event to locate handlers.

Parameters:

pmb - Event from CDI SPI

bm - Activated Bean Manager

Throws:

TypeNotPresentException - if any of the actual type arguments refers to a non-existent type declaration when trying to obtain the actual type arguments from a ParameterizedType

MalformedParameterizedTypeException - if any of the actual type parameters refer to a parameterized type that cannot be instantiated for any reason when trying to obtain the actual type arguments from a ParameterizedType

verifyInjectionPoints

public void verifyInjectionPoints(@Observes
                         javax.enterprise.inject.spi.AfterDeploymentValidation adv,
                         javax.enterprise.inject.spi.BeanManager bm)

Verifies all injection points for every handler are valid.

Parameters:

adv - Lifecycle event

bm - BeanManager instance

getHandlersForExceptionType

public Collection<HandlerMethod<? extends Throwable>> getHandlersForExceptionType(Type exceptionClass,
                                                                         javax.enterprise.inject.spi.BeanManager bm,
                                                                         Set<Annotation> handlerQualifiers,
                                                                         TraversalMode traversalMode)

Obtains the applicable handlers for the given type or super type of the given type. Also makes use of ExceptionHandlerComparator to order the handlers.

Parameters:

exceptionClass - Type of exception to narrow handler list

bm - active BeanManager

handlerQualifiers - additional handlerQualifiers to limit handlers

traversalMode - traversal limiter

Returns:

An order collection of handlers for the given type.

registerHandlerMethod

public <T extends Throwable> void registerHandlerMethod(HandlerMethod<T> handlerMethod)

Description copied from interface: HandlerMethodContainer

Registers the given handlerMethod to the container.

Specified by:

registerHandlerMethod in interface HandlerMethodContainer

Parameters:

handlerMethod - HandlerMethod implementation to register with the container
