Class AbstractAttributeHandler

java.lang.Object

com.sun.enterprise.deployment.annotation.handlers.AbstractHandler

org.glassfish.ejb.deployment.annotation.handlers.AbstractAttributeHandler

All Implemented Interfaces:

AnnotationHandler

Direct Known Subclasses:

AccessTimeoutHandler, AfterBeginHandler, AfterCompletionHandler, AroundConstructHandler, AroundInvokeHandler, AsynchronousHandler, BeforeCompletionHandler, ConcurrencyManagementHandler, ExcludeClassInterceptorsHandler, ExcludeDefaultInterceptorsHandler, InitHandler, InterceptorsHandler, LockHandler, PostActivateHandler, PrePassivateHandler, RemoveHandler, ScheduleHandler, StatefulTimeoutHandler, TimeoutHandler, TransactionAttributeHandler, TransactionManagementHandler

public abstract class AbstractAttributeHandler
extends AbstractHandler

This is an abstract class encapsulate generic behaviour of annotation handler applying on Ejb Class. It will get the corresponding EjbDescriptors associated to the annotation on the given Ejb Class and then pass it to underlying processAnnotation method. Concrete subclass handlers need to implement the following: public Class<? extends Annotation> getAnnotationType(); protected HandlerProcessingResult processAnnotation(AnnotationInfo ainfo, EjbContext[] ejbContexts) throws AnnotationProcessorException; It may also need to override the following: a) if other annotations need to be processed prior to given annotation: public Class<? extends Annotation>[] getTypeDependencies(); b) if the given annotation can be processed while processing another annotation protected boolean isDelegatee(); c) if we need to process for interceptor protected HandlerProcessingResult processAnnotation(AnnotationInfo ainfo, EjbInterceptorContext ejbInterceptorContext) throws AnnotationProcessorException; d) indicate the annotation support type inheritance protected boolean supportTypeIneritance();

processAnnotation

protected abstract HandlerProcessingResult processAnnotation(AnnotationInfo ainfo,
                                                             EjbContext[] ejbContexts)
                                                      throws AnnotationProcessorException

Process Annotation with given EjbContexts.

Parameters:

ainfo -

ejbContexts -

Returns:

HandlerProcessingResult

Throws:

AnnotationProcessorException

processAnnotation

protected HandlerProcessingResult processAnnotation(AnnotationInfo ainfo,
                                                    EjbInterceptorContext ejbInterceptorContext)
                                             throws AnnotationProcessorException

Process Annotation with given InteceptorContext.

Parameters:

ainfo -

ejbInterceptorContext -

Returns:

HandlerProcessingResult

Throws:

AnnotationProcessorException

processAnnotation

public HandlerProcessingResult processAnnotation(AnnotationInfo ainfo)
                                          throws AnnotationProcessorException

Process a particular annotation which type is the same as the one returned by @see getAnnotationType(). All information pertinent to the annotation and its context is encapsulated in the passed AnnotationInfo instance. This is a method in interface AnnotationHandler.

Parameters:

ainfo - the annotation information

Throws:

AnnotationProcessorException

isDelegatee

protected boolean isDelegatee()

This indicates whether the annotation can be processed by delegation from the another annotation.

supportTypeInheritance

protected boolean supportTypeInheritance()

This indicates whether the annotation type should be processed for type level in super-class.
