Interface AnnotationDescription

All Known Subinterfaces:

AnnotationDescription.Loadable<S>

public interface AnnotationDescription

An annotation description describes Annotation meta data of a class without this class being required to be loaded. All values of an annotation are therefore represented in unloaded state:

• Class instances are represented as TypeDescriptions.
• Enum instances are represented as EnumerationDescriptions.
• Annotations are described as AnnotationDescriptions.
• All primitive types are represented as their wrapper types.

An annotation can however be loaded in order to access unwrapped values. This will cause a loading of the classes of these values.

Field Detail

UNDEFINED

@AlwaysNull
static final AnnotationDescription.Loadable<?> UNDEFINED

Indicates a nonexistent annotation in a type-safe manner.

Method Detail

getValue

AnnotationValue<?,?> getValue(java.lang.String property)

Returns a value of this annotation.

Parameters:

property - The name of the property being accessed.

Returns:

The value for the supplied property.

getValue

AnnotationValue<?,?> getValue(MethodDescription.InDefinedShape property)

Returns a value of this annotation.

Parameters:

property - The property being accessed.

Returns:

The value for the supplied property.

getAnnotationType

TypeDescription getAnnotationType()

Returns a description of the annotation type of this annotation.

Returns:

A description of the annotation type of this annotation.

prepare

<T extends java.lang.annotation.Annotation> AnnotationDescription.Loadable<T> prepare(java.lang.Class<T> annotationType)

Links this annotation description to a given annotation type such that it can be loaded. This does not cause the values of this annotation to be loaded.

Type Parameters:

T - The type of the annotation.

Parameters:

annotationType - The loaded annotation type of this annotation description.

Returns:

A loadable version of this annotation description.

getRetention

java.lang.annotation.RetentionPolicy getRetention()

Returns this annotation's retention policy.

Returns:

This annotation's retention policy.

getElementTypes

java.util.Set<java.lang.annotation.ElementType> getElementTypes()

Returns a set of all ElementTypes that can declare this annotation.

Returns:

A set of all element types that can declare this annotation.

isSupportedOn

boolean isSupportedOn(java.lang.annotation.ElementType elementType)

Checks if this annotation is supported on the supplied element type.

Parameters:

elementType - The element type to check.

Returns:

true if the supplied element type is supported by this annotation.

isSupportedOn

boolean isSupportedOn(java.lang.String elementType)

Checks if this annotation is supported on the supplied element type.

Parameters:

elementType - The element type to check.

Returns:

true if the supplied element type is supported by this annotation.

isInherited

boolean isInherited()

Checks if this annotation is inherited.

Returns:

true if this annotation is inherited.

Inherited

isDocumented

boolean isDocumented()

Checks if this annotation is documented.

Returns:

true if this annotation is documented.
