Method Detail

getBaseType

java.lang.reflect.Type getBaseType()

Get the type of the annotated program element.

Returns:

the type of the annotated program element

getTypeClosure

java.util.Set<java.lang.reflect.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 java.lang.annotation.Annotation> T getAnnotation(java.lang.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

java.util.Set<java.lang.annotation.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(java.lang.Class<? extends java.lang.annotation.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
