Method Summary

Methods

Modifier and Type	Method and Description
<T extends Annotation> T	getAnnotation(Class<T> annotationType) Get program element annotation of a certain annotation type.
Set<Annotation>	getAnnotations() Get all annotations of the program element.
Type	getBaseType() Get the type of the annotated program element.
Set<Type>	getTypeClosure() Get all types to which the base type should be considered assignable.
boolean	isAnnotationPresent(Class<? extends Annotation> annotationType) Determine if the program element has an annotation of a certain annotation type.

Method Detail

getBaseType

Type getBaseType()

Get the type of the annotated program element.

Returns:

the type of the annotated program element

getTypeClosure

Set<Type> getTypeClosure()

Get all types to which the base type should be considered assignable.

Returns:

a set of all types to which the base type should be considered assignable

getAnnotation

<T extends Annotation> T getAnnotation(Class<T> annotationType)

Get program element annotation of a certain annotation type.

Type Parameters:

T - the type of the annotation

Parameters:

annotationType - the class of the annotation type

Returns:

the program element annotation of the given annotation type, or a null value

getAnnotations

Set<Annotation> getAnnotations()

Get all annotations of the program element.

Returns:

all annotations of the program element, or an empty set if no annotations are present

isAnnotationPresent

boolean isAnnotationPresent(Class<? extends Annotation> annotationType)

Determine if the program element has an annotation of a certain annotation type.

Parameters:

annotationType - the annotation type to check for

Returns:

true if the program element has an annotation of the given annotation type, or false otherwise
