Method Details

isSupportedAnnotationClass

protected boolean isSupportedAnnotationClass(Class<? extends Annotation> annoClass)

Custom filter for units annotations:

This filter will ignore (by returning false) any units annotation which is an alias of another base unit annotation (identified via UnitsMultiple meta-annotation). Alias annotations can still be used in source code; they are converted into a base annotation by UnitsAnnotatedTypeFactory.canonicalAnnotation(AnnotationMirror) or AnnotatedTypeFactory.canonicalAnnotation(AnnotationMirror,TypeMirror). This filter simply makes sure that the alias annotations themselves don't become part of the type hierarchy as their canonical annotations already are in the hierarchy.

Overrides:

isSupportedAnnotationClass in class AnnotationClassLoader

Parameters:

annoClass - an annotation class

Returns:

true if the annotation is supported, false if it isn't
