                                                Class<?>... args)

getDeclaredConstructors

public static <T> Constructor<T>[] getDeclaredConstructors(Class<T> cls)

getDeclaredMethods

public static Method[] getDeclaredMethods(Class<?> cls)

getDeclaredMethod

public static Method getDeclaredMethod(Class<?> clazz,
                                       String name,
                                       Class<?>... parameterTypes)
                                throws NoSuchMethodException

Throws:

NoSuchMethodException

getDeclaredFields

public static Field[] getDeclaredFields(Class<?> cls)

setAccessible

public static <T extends AccessibleObject> T setAccessible(T o)

setAccessible

public static <T extends AccessibleObject> T setAccessible(T o,
                                                           boolean b)

getPropertyDescriptorsAvoidSunBug

public static PropertyDescriptor[] getPropertyDescriptorsAvoidSunBug(Class<?> refClass,
                                                                     BeanInfo beanInfo,
                                                                     Class<?> beanClass,
                                                                     PropertyDescriptor[] propertyDescriptors)

create own array of property descriptors to:

  - prevent memory leaks by Introspector's cache
  - get correct type for generic properties from superclass
     that are limited to a specific type in beanClass
    see http://bugs.sun.com/view_bug.do?bug_id=6528714
   we cannot use BeanUtils.getPropertyDescriptors because of issue SPR-6063
   

Parameters:

refClass - calling class for class loading.

beanInfo - Bean in question

beanClass - class for bean in question

propertyDescriptors - raw descriptors

getAnnotationForMethodOrContainingClass

public static <T extends Annotation> T getAnnotationForMethodOrContainingClass(Method m,
                                                                               Class<T> annotationType)

Look for a specified annotation on a method. If there, return it. If not, search it's containing class. Assume that the annotation is marked @Inherited.

Parameters:

m - method to examine

annotationType - the annotation type to look for.
