forEachMethodInTopDownHierarchy

public static void forEachMethodInTopDownHierarchy(@Nonnull
 Object object,
 @Nonnull
 ReflectionUtils.MethodProcessor processor)

Parameters:

object - the object at the bottom of the hierarchy

processor - the processor

forEachMethodInBottomUpHierarchy

public static void forEachMethodInBottomUpHierarchy(@Nonnull
 Object object,
 @Nonnull
 ReflectionUtils.MethodProcessor processor)

Navigates the hierarchy of the given object, bottom up (that is, starting from the class of the object), and applies the ReflectionUtils.MethodProcessor to all the methods of each class, if not filtered out by the processor itself.

Parameters:

object - the object at the bottom of the hierarchy

processor - the processor

containsAnnotation

public static boolean containsAnnotation(@Nonnull
 Annotation[] annotations,
 @Nonnull
 Class<?> annotationClass)
