Class AnnotationDescriptor<T extends Annotation>

java.lang.Object
  org.hibernate.validator.util.annotationfactory.AnnotationDescriptor<T>

public class AnnotationDescriptor<T extends Annotation>
extends Object

Encapsulates the data you need to create an annotation. In particular, it stores the type of an Annotation instance and the values of its elements. The "elements" we're talking about are the annotation attributes, not its targets (the term "element" is used ambiguously in Java's annotations documentation).

Method Detail

getInstance

public static <S extends Annotation> AnnotationDescriptor<S> getInstance(Class<S> annotationType)

Returns a new descriptor for the given annotation type.

Type Parameters:

S - The type of the annotation.

Parameters:

annotationType - The annotation's class.

Returns:

A new descriptor for the given annotation type.

getInstance

public static <S extends Annotation> AnnotationDescriptor<S> getInstance(Class<S> annotationType,
                                                                         Map<String,Object> elements)

Returns a new descriptor for the given annotation type.

Type Parameters:

S - The type of the annotation.

Parameters:

annotationType - The annotation's class.

elements - A map with attribute values for the annotation to be created.

Returns:

A new descriptor for the given annotation type.

setValue

public void setValue(String elementName,
                     Object value)

valueOf

public Object valueOf(String elementName)

containsElement

public boolean containsElement(String elementName)

numberOfElements

public int numberOfElements()

getElements

public Map<String,Object> getElements()

Returns a map with the elements contained in this descriptor keyed by name. This map is a copy of the internally used map, so it can safely be modified without altering this descriptor.

Returns:

A map with this descriptor's elements.

type

public Class<T> type()
