Interface AnnotationMetadata

All Superinterfaces:

AnnotatedTypeMetadata, ClassMetadata

All Known Implementing Classes:

AnnotationMetadataReadingVisitor, StandardAnnotationMetadata

public interface AnnotationMetadata
extends ClassMetadata, AnnotatedTypeMetadata

Interface that defines abstract access to the annotations of a specific class, in a form that does not require that class to be loaded yet.

Method Detail

getAnnotationTypes

Set<String> getAnnotationTypes()

Return the names of all annotation types that are present on the underlying class.

Returns:

the annotation type names

getMetaAnnotationTypes

Set<String> getMetaAnnotationTypes(String annotationType)

Return the names of all meta-annotation types present on the given annotation type on the underlying class.

Parameters:

annotationType - the meta-annotation type to look for

Returns:

the meta-annotation type names

hasAnnotation

boolean hasAnnotation(String annotationType)

Determine whether an annotation of the given type is present on the underlying class.

Parameters:

annotationType - the annotation type to look for

Returns:

whether a matching annotation is present

hasMetaAnnotation

boolean hasMetaAnnotation(String metaAnnotationType)

Determine whether the underlying class has an annotation that is itself annotated with the meta-annotation of the given type.

Parameters:

metaAnnotationType - the meta-annotation type to look for

Returns:

whether a matching meta-annotation is present

hasAnnotatedMethods

boolean hasAnnotatedMethods(String annotationType)

Determine whether the underlying class has any methods that are annotated (or meta-annotated) with the given annotation type.

getAnnotatedMethods

Set<MethodMetadata> getAnnotatedMethods(String annotationType)

Retrieve the method metadata for all methods that are annotated (or meta-annotated) with the given annotation type.

For any returned method, AnnotatedTypeMetadata.isAnnotated(java.lang.String) will return true for the given annotation type.

Parameters:

annotationType - the annotation type to look for

Returns:

a set of MethodMetadata for methods that have a matching annotation. The return value will be an empty set if no methods match the annotation type.
