Method Detail

getAdapterInterfaces

protected Class<?>[] getAdapterInterfaces()

Description copied from class: AbstractAnnotationHandlerBeanPostProcessor

Returns the interface that the adapter implements to connect the annotated method to the actual interface definition. Calls to methods declared on this interface are passed to the adapter, while other method calls will be forwarded to the annotated object itself.

Note: this *must* be an interface. It may not be an (abstract) class.

Specified by:

getAdapterInterfaces in class AbstractAnnotationHandlerBeanPostProcessor<QueryHandlerAdapter,AnnotationQueryHandlerAdapter>

Returns:

the interface that the adapter implements to connect the annotated method to the actual interface definition

isPostProcessingCandidate

protected boolean isPostProcessingCandidate(Class<?> targetClass)

Description copied from class: AbstractAnnotationHandlerBeanPostProcessor

Indicates whether an object of the given targetClass should be post processed.

Specified by:

isPostProcessingCandidate in class AbstractAnnotationHandlerBeanPostProcessor<QueryHandlerAdapter,AnnotationQueryHandlerAdapter>

Parameters:

targetClass - The type of bean

Returns:

true to post process bean of given type, false otherwise

initializeAdapterFor

protected AnnotationQueryHandlerAdapter initializeAdapterFor(Object o,
                                                             ParameterResolverFactory parameterResolverFactory)

Description copied from class: AbstractAnnotationHandlerBeanPostProcessor

Create an AnnotationEventListenerAdapter instance of the given bean. This adapter will receive all event handler calls to be handled by this bean.

Specified by:

initializeAdapterFor in class AbstractAnnotationHandlerBeanPostProcessor<QueryHandlerAdapter,AnnotationQueryHandlerAdapter>

Parameters:

o - The bean that the EventListenerAdapter has to adapt

parameterResolverFactory - The parameter resolver factory that provides the parameter resolvers for the annotated handlers

Returns:

an event handler adapter for the given bean
