boolean containsAnnotation(Class<?> javaClass,
                         Class<? extends Annotation> annotation)

Deprecated.

Indicates whether the given class contains an annotation of the given annotation type.

The process begins with enumerating a set of annotations which consists of:

• the given annotation
• any annotation present in the deployment which on which the given annotation is present as a meta-annotation (as returned by ExtendedAnnotationDiscovery.getAnnotationsAnnotatedWith(Class))

The set is referred to as M hereafter

The given class is said to contain the given annotation if any of these applies:

• A member of M is present on the class
• A member of M, which is annotated with Inherited, is present on a direct or indirect superclass of the given class
• A member of M is present on a field or method declared by the given class or any direct or indirect superclass of the given class
• A member of M is present on a parameter of a method declared by the given class or any direct or indirect superclass of the given class
• A member of M is present on a constructor declared by the given class
• A member of M is present on a parameter of a constructor declared by the given class

This is a per-deployment service.

Parameters:

javaClass - the given class

annotation - the given annotation type

Returns:
