Method Details

from

public static AnnotatedElementAdapter from(Annotation @Nullable [] annotations)

Create an AnnotatedElementAdapter from the supplied annotations.

The supplied annotations will be considered to be both present and directly present with regard to the results returned from methods such as getAnnotation(Class), getDeclaredAnnotation(Class), etc.

If the supplied annotations array is either null or empty, this factory method will return an empty adapter.

Parameters:

annotations - the annotations to expose via the AnnotatedElement API

Returns:

a new AnnotatedElementAdapter
