Alexander Müller commented on LANG-1021:
----------------------------------------
I agree that putting a method used for retrieving a list of fields/methods
makes sense in {{FieldUtils}}/{{MethodUtils}} but thought that - since no other
annotation-specific method is defined outside {{AnnotationUtils}} - these
methods should be in {{AnnotationUtils}} to keep consistency. If there are
plans to add other methods used to retrieve lists of fields/methods, I'd rather
see them in {{FieldUtils}}/{{MethodUtils}}, e.g. {{getMethodsStartingWIth()}}
({{Field[] getters = gettergetMethodsStartingWith("get")}}.
I really don't have a sophisticated opinion on where to put these methods. I
picked the first criterion I could imagine (consistency: annotation stuff goes
to {{AnnotationUtils}}).

> Key: LANG-1021

> Project: Commons Lang
> Issue Type: New Feature

> Reporter: Alexander Müller
> Fix For: Review Patch

>
> I find myself repeatedly searching for fields (or methods) that are annotated
> with a specified annotation like this (field-only example):
> {code}
> List<Field> fieldsWithAnnotation = new ArrayList<>();
> Field[] fields = FieldUtils.getAllFields(type);
> for (Field field : fields) {
> Annotation fieldAnnotation = field.getAnnotation(annotation);
> if (fieldAnnotation != null) {
> fieldsWithAnnotation.add(fieldAnnotation);
> }
> }
> {code}
> Commons Lang could provide these methods:
> {code}
> public Field[] AnnotationUtils.getFieldsWithAnnotation(Annotation annotation);
> public List<Field> AnnotationUtils.getFieldListWithAnnotation(Annotation
> annotation);
> public Method[] AnnotationUtils.getMethodsWithAnnotation(Annotation
> annotation);
> public List<Method> AnnotationUtils.getMethodListWithAnnotation(Annotation
> annotation);
> {code}
