Interface AnnotationMetadata

All Superinterfaces:

ClassMetadata

All Known Implementing Classes:

StandardAnnotationMetadata

public interface AnnotationMetadata
extends ClassMetadata

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 Summary

Map<String,Object>	getAnnotationAttributes(String annotationType) Retrieve the attributes of the annotation of the given type, if any (i.e. if defined on the underlying class).
Set<String>	getAnnotationTypes() Return the names of all annotation types defined on the underlying class.
Set<String>	getMetaAnnotationTypes(String annotationType) Return the names of all meta-annotation types defined on the given annotation type of the underlying class.
boolean	hasAnnotation(String annotationType) Determine whether the underlying class has an annotation of the given type defined.
boolean	hasMetaAnnotation(String metaAnnotationType) Determine whether the underlying class has an annotation that is itself annotated with the meta-annotation of the given type.

Method Detail

getAnnotationTypes

Set<String> getAnnotationTypes()

Return the names of all annotation types defined on the underlying class.

Returns:

the annotation type names

hasAnnotation

boolean hasAnnotation(String annotationType)

Determine whether the underlying class has an annotation of the given type defined.

Parameters:

annotationType - the annotation type to look for

Returns:

whether a matching annotation is defined

getMetaAnnotationTypes

Set<String> getMetaAnnotationTypes(String annotationType)

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

Returns:

the meta-annotation type names

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 defined

getAnnotationAttributes

Map<String,Object> getAnnotationAttributes(String annotationType)

Retrieve the attributes of the annotation of the given type, if any (i.e. if defined on the underlying class).

Parameters:

annotationType - the annotation type to look for

Returns:

a Map of attributes, with the attribute name as key (e.g. "value") and the defined attribute value as Map value. This return value will be null if no matching annotation is defined.
