方法详细资料
getAnnotationTypes
Set<String> getAnnotationTypes()
Get the fully qualified class names of all annotation types that are present on the underlying class.- 返回:
- the annotation type names
getMetaAnnotationTypes
Set<String> getMetaAnnotationTypes(String annotationName)
Get the fully qualified class names of all meta-annotation types that are present on the given annotation type on the underlying class.- 参数:
annotationName- the fully qualified class name of the meta-annotation type to look for- 返回:
- the meta-annotation type names
hasAnnotation
boolean hasAnnotation(String annotationName)
Determine whether an annotation of the given type is present on the underlying class.- 参数:
annotationName- the fully qualified class name of the annotation type to look for- 返回:
trueif a matching annotation is present
hasMetaAnnotation
boolean hasMetaAnnotation(String metaAnnotationName)
Determine whether the underlying class has an annotation that is itself annotated with the meta-annotation of the given type.- 参数:
metaAnnotationName- the fully qualified class name of the meta-annotation type to look for- 返回:
trueif a matching meta-annotation is present
hasAnnotatedMethods
boolean hasAnnotatedMethods(String annotationName)
Determine whether the underlying class has any methods that are annotated (or meta-annotated) with the given annotation type.- 参数:
annotationName- the fully qualified class name of the annotation type to look for
getAnnotatedMethods
Set<MethodMetadata> getAnnotatedMethods(String annotationName)
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 returntruefor the given annotation type.- 参数:
annotationName- the fully qualified class name of the annotation type to look for- 返回:
- a set of
MethodMetadatafor methods that have a matching annotation. The return value will be an empty set if no methods match the annotation type.
