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)

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)
