Method Detail

getAnnotationClassValue

static <T extends Annotation> TypeMirror getAnnotationClassValue(Elements elements,
                                                                 T anno,
                                                                 Function<T,Class<?>> func)

For Class attribute, if we invoke directly, it will throw MirroredTypeException. Use this method to get the Class value safely.

Parameters:

elements - Elements for convert Class to TypeMirror

anno - annotation object

func - the invocation of get Class value

Returns:

the value's TypeMirror

getAnnotationClassArray

static <T extends Annotation> List<TypeMirror> getAnnotationClassArray(Elements elements,
                                                                       T anno,
                                                                       Function<T,Class<?>[]> func)

getAnnotationMirror

static Optional<AnnotationMirror> getAnnotationMirror(Element element,
                                                      Class<? extends Annotation> annotationClass)

Get AnnotationMirror from given element with given type

Parameters:

element - the element to find annotation

annotationClass - the annotation class

Returns:

the AnnotationMirror

getAnnotationMirror

static Optional<AnnotationMirror> getAnnotationMirror(Element element,
                                                      TypeMirror annotationType)

Get AnnotationMirror from given element with given type

Parameters:

element - the element to find annotation

annotationType - the annotation TypeMirror

Returns:

the AnnotationMirror

getAnnotationMirror

static Optional<AnnotationMirror> getAnnotationMirror(Element element,
                                                      String annoClzCanonicalName)

Get AnnotationMirror from given element with given annotation name

Parameters:

element - the element to find annotation

annoClzCanonicalName - the annotation name

Returns:

the AnnotationMirror

getInheritAnnotationMirrors

static List<? extends AnnotationMirror> getInheritAnnotationMirrors(TypeElement element,
                                                                    Types types)

isInherit

static boolean isInherit(DeclaredType annoType)

getAllSubClasses

static Stream<TypeElement> getAllSubClasses(Types types,
                                            RoundEnvironment env,
                                            TypeMirror type)

getAllSubClasses

static Stream<TypeElement> getAllSubClasses(Types types,
                                            Element root,
                                            TypeMirror type)
