getAnnotationClassValue

public static <T extends Annotation> TypeMirror getAnnotationClassValue(Elements elements,
                                                                        T anno,
                                                                        java.util.function.Function<T,Class<?>> func)

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

参数:

elements - Elements for convert Class to TypeMirror

anno - annotation object

func - the invocation of get Class value

返回:

the value's TypeMirror

getAnnotationMirror

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

Get AnnotationMirror from given element with given type

参数:

element - the element to find annotation

annotationClass - the annotation class

返回:

the AnnotationMirror

getAnnotationMirror

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

Get AnnotationMirror from given element with given type

参数:

element - the element to find annotation

annotationType - the annotation TypeMirror

返回:

the AnnotationMirror

getAnnotationMirror

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

Get AnnotationMirror from given element with given annotation name

参数:

element - the element to find annotation

annoClzCanonicalName - the annotation name

返回:

the AnnotationMirror
