public class AnnotationTypeFilter extends AbstractTypeHierarchyTraversingFilter
TypeFilter
which matches classes with a given annotation,
checking inherited annotations as well.
By default, the matching logic mirrors that of
AnnotationUtils.getAnnotation(java.lang.reflect.AnnotatedElement, Class)
,
supporting annotations that are present or meta-present for a
single level of meta-annotations. The search for meta-annotations may be disabled.
Similarly, the search for annotations on interfaces may optionally be enabled.
Consult the various constructors in this class for details.

public AnnotationTypeFilter(Class<? extends Annotation> annotationType)
AnnotationTypeFilter
for the given annotation type.
The filter will also match meta-annotations. To disable the
meta-annotation matching, use the constructor that accepts a
'considerMetaAnnotations
' argument.
The filter will not match interfaces.
