AnnotationProcessing_Advanced

Collect the common PAP cases here:

Obtain all fields defined in the element

TypeElement typeElement = ...;

for (TypeMirror field: ElementFilter.fieldsIn(type.getEnclosedElements()) {
    //... process field
}

Converting type to the mutable type

MutableProcessingEnvironment processingEnv = ...; //defined in the MutableAnnotationProcessor
TypeMirror type = ...;
MutableTypeMirror mutableType = processingEnv.getTypeUtils().toMutable(type);

Specifying super class of the generated class

MutableProcessingEnvironment processingEnv = ...;
MutableTypeMirror mutableType = ...;

mutableType.setSuperClass(processingEnv.getTypeUtils().toMutable(BufferedReader.class));

Specifying types super class of the generated class

MutableProcessingEnvironment processingEnv = ...;
MutableTypeMirror mutableType = ...;

mutableType.setSuperClass(processingEnv.getTypeUtils().toMutable(List.class));
