Annotations

Annotation Manipulation using Mirror.

Reflecting

You can easily reflect all annotations from a class:


Class<T> clazz;

List<Annotation> annotations = new Mirror().on(clazz).reflectAll()

                                    .annotations().atClass();

As you can also easily reflect all annotations from a field or from a method:


Class<T> clazz;

List<Annotation> methodAnnotations = new Mirror().on(clazz).reflectAll()

                            .annotations().atMethod("methodName").withoutArgs();

                            

List<Annotation> fieldAnnotations = new Mirror().on(clazz).reflectAll()

                            .annotations().atField("fieldName");

It's also possible to retrieve a value from an annotation property, just like the following snippet:


FooAnnotation annotation = new Mirror().on(clazz).reflect()

                                    .annotation(FooAnnotation.class).atClass();

String propertyValue = annotation.aProperty();

And it also works similarly for fields and methods annotations:


FooAnnotation annotation = new Mirror().on(clazz).reflect()

                        .annotation(FooAnnotation.class).atField("fieldName");

String fieldPropertyValue = annotation.aProperty();



FooAnnotation annotation = new Mirror().on(clazz).reflect()

                        .annotation(FooAnnotation.class)

                        .atMethod("methodName").withoutArgs();

String methodPropertyValue = annotation.aProperty();
