Interface AnnotationProcessor<A extends Annotation,E extends CtElement>

All Superinterfaces:

FactoryAccessor, Processor<E>

All Known Implementing Classes:

AbstractAnnotationProcessor

public interface AnnotationProcessor<A extends Annotation,E extends CtElement>
extends Processor<E>

This interface defines an annotation processor. An annotation processor is triggered by Spoon when a visited element is annotated with one of the processed or consumed annotations. To define a new annotation processor, the user should subclass AbstractAnnotationProcessor, the abstract default implementation of this interface.

Method Summary

Modifier and Type	Method	Description
Set<Class<? extends A>>	getConsumedAnnotationTypes()	Gets the annotations types consumed by this processor.
Set<Class<? extends A>>	getProcessedAnnotationTypes()	Gets the annotations processed by this annotation processor, that is to say the annotation types that trigger the process(Annotation, CtElement) method when visiting a program element.
boolean	inferConsumedAnnotationType()	Returns true (default) if the processor automatically infers the consumed annotation type to the A actual type.
void	process(A annotation, E element)	Do the annotation processing job for a given annotation.
boolean	shoudBeConsumed(CtAnnotation<? extends Annotation> annotation)	Returns true if this annotation should be removed from the processed code.

Method Details

process

void process(A annotation,
 E element)

Do the annotation processing job for a given annotation.

Parameters:

annotation - the annotation to process

element - the element that holds the processed annotations

getProcessedAnnotationTypes

Set<Class<? extends A>> getProcessedAnnotationTypes()

Gets the annotations processed by this annotation processor, that is to say the annotation types that trigger the process(Annotation, CtElement) method when visiting a program element. The processed annotation types includes all the consumed annotation types.

Returns:

the annotation classes

getConsumedAnnotationTypes

Set<Class<? extends A>> getConsumedAnnotationTypes()

Gets the annotations types consumed by this processor. A consumed annotation is a special kind of processed annotation (see getProcessedAnnotationTypes() that is automatically removed from the program once the associated processor has finished its job.

Returns:

the annotation classes

inferConsumedAnnotationType

boolean inferConsumedAnnotationType()

Returns true (default) if the processor automatically infers the consumed annotation type to the A actual type.

shoudBeConsumed

boolean shoudBeConsumed(CtAnnotation<? extends Annotation> annotation)

Returns true if this annotation should be removed from the processed code.
