        boolean isAnnotationPresent(Class<? extends Annotation> annotationClass)
        Returns true if an annotation for the specified type is present on this element, else false. This method is designed primarily for convenient access to marker annotations.
        Parameters:
        annotationClass - the Class object corresponding to the annotation type
        Returns:
        true if an annotation for the specified annotation type is present on this element, else false
        Throws:
        NullPointerException - if the given annotation class is null
        Since:
        1.5
      • getAnnotation

        <T extends Annotation> T getAnnotation(Class<T> annotationClass)
        Returns this element's annotation for the specified type if such an annotation is present, else null.
        Parameters:
        annotationClass - the Class object corresponding to the annotation type
        Returns:
        this element's annotation for the specified annotation type if present on this element, else null
        Throws:

      • getAnnotations

        Annotation[] getAnnotations()
        Returns all annotations present on this element. (Returns an array of length zero if this element has no annotations.) The caller of this method is free to modify the returned array; it will have no effect on the arrays returned to other callers.
        Returns:
        all annotations present on this element
        Since:
