findMethodWithAnnotation

public static <T extends java.lang.annotation.Annotation> java.util.Optional<java.lang.reflect.Method> findMethodWithAnnotation(java.lang.reflect.Method provided,
                                                                                                                                java.lang.Class<T> annotationCls)

Looks through the method's declaring class's hierarchy to find a method with a compatible which is annotated with the provided annotation. This is particularly useful if an interface or superclass's method is annotated for a specific reason and a child class overrides it to change the implementation. In that case, this method can be used to get the parent class's method object so the annotations can be read (including Parameter annotations!).

Type Parameters:

T - The type of the Annotation to be searched for.

Parameters:

provided - The method to look for the most recent implementation of using this annotation

annotationCls - The annotation the method must contain.

Returns:

Optionally, returns a method that has been annotated with annotationCls. If none is found, empty.
