annotation - Annotation to be processed

annotationInstance - Annotation instance to be processed

processMethod

public void processMethod(Method method,
 Class<? extends Annotation> annotation,
 Annotation annotationInstance)

Description copied from interface: MethodHook

Process the given method with the given annotation.

Specified by:

method - Method to be processed

annotation - Annotation to be processed

annotationInstance - Annotation instance to be processed

addBeanProvider

public void addBeanProvider(BeanProvider<?> beanProvider)

Add a bean provider from a framework module.

Parameters:

beanProvider - Bean provider to be added

getBean

public <T> T getBean(Class<T> clazz)
