Method Detail

getBaseType

java.lang.reflect.Type getBaseType()

Get the type of the annotated element

Returns:

the type

getTypeClosure

java.util.Set<java.lang.reflect.Type> getTypeClosure()

Returns:

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

getAnnotation

<T extends java.lang.annotation.Annotation> T getAnnotation(java.lang.Class<T> annotationType)

Type Parameters:

T - the type of the annotation

Parameters:

annotationType - the class object of the annotation type

Returns:

the annotation instance, or null if no annotation is present for the given annotationType

getAnnotations

java.util.Set<java.lang.annotation.Annotation> getAnnotations()

Returns:

the annotation instances, or an empty set if no annotations are present

isAnnotationPresent

boolean isAnnotationPresent(java.lang.Class<? extends java.lang.annotation.Annotation> annotationType)

Determine if an annotation is present on the annotated element

Parameters:

annotationType - the annotation type to check for

Returns:

true if the annotation is present
