        Parameters:
        aMethod - Method to be checked.
        someAnnotationTypes - Types that should be collected.
        Returns:
        A list of all parameters linked to the annotation of the given types for this method.

      • isOneOf

        Produces a predicate that matches an annotation if it is one of the specified ones.
        Parameters:
        someAnnotationTypes - Annotations that should match.
        Returns:
        true if the annotation represents one of the specified ones, false otherwise.

        Extracts an annotation value by its name.
        Parameters:
        anAnnotation - Annotation where to search.
        aName - Name to be searched.
        Returns:
        annotation value if it got found, null otherwise.
