Method Detail

getBaseType

public Type getBaseType()

Description copied from interface: Annotated

Get the type of the annotated program element.

Specified by:

getBaseType in interface Annotated

Returns:

the type of the annotated program element

getTypeClosure

public Set<Type> getTypeClosure()

Description copied from interface: Annotated

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

Specified by:

getTypeClosure in interface Annotated

Returns:

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

getAnnotation

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

Description copied from interface: Annotated

Get program element annotation of a certain annotation type. The behavior of this method is intended to be the same behavior as AnnotatedElement.getAnnotation(Class), where repeatable annotations are not supported.

Specified by:

getAnnotation in interface Annotated

Type Parameters:

T - the type of the annotation

Parameters:

annotationType - the class of the annotation type

Returns:

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

getAnnotations

public <T extends Annotation> Set<T> getAnnotations(Class<T> annotationType)

Description copied from interface: Annotated

Get program element annotations of a certain annotation type.

This method returns back all annotations, including repeatable annotations of this type. The behavior of this method is intended to be the same behavior as AnnotatedElement.getAnnotationsByType(Class), where repeatable annotations are supported.

Specified by:

getAnnotations in interface Annotated

Type Parameters:

T - the type of the annotation

Parameters:

annotationType - the class of the annotation type

Returns:

the program element annotations of the given annotation type, or an empty collection

getAnnotations

public Set<Annotation> getAnnotations()

Description copied from interface: Annotated

Get all annotations of the program element.

Specified by:

getAnnotations in interface Annotated

Returns:

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

isAnnotationPresent

public boolean isAnnotationPresent(Class<? extends Annotation> annotationType)

Description copied from interface: Annotated

Determine if the program element has an annotation of a certain annotation type. The behavior of this method is similar to AnnotatedElement.isAnnotationPresent(Class) for the underlying program element.

Specified by:

isAnnotationPresent in interface Annotated

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
