Method Detail

setField

public static void setField(Object obj,
                            String fieldName,
                            Object value)

getAnnotation

public static <T extends Annotation> T getAnnotation(Class<?> clazz,
                                                     String fieldName,
                                                     Class<T> annotationClass)

getAnnotation

public static <T extends Annotation> T getAnnotation(Class<?> clazz,
                                                     Class<T> annotationClass)

getField

public static <T> T getField(Object obj,
                             String fieldName)

getDeclaredField

public static Field getDeclaredField(Class<?> clazz,
                                     String fieldName)
                              throws NoSuchFieldException

Throws:

NoSuchFieldException

isAnnotationPresent

public static boolean isAnnotationPresent(Class<?> clazz,
                                          Class<? extends Annotation> annotation)

searchForMethod

public static Method searchForMethod(Class<?> type,
                                     String name,
                                     Class<?>[] parms)

Searches through all methods looking for one with the specified name that will take the specified paramaters even if the parameter types are more generic in the actual method implementation. This is similar to the findConstructor() method and has the similar limitations that it doesn't do a real widening scope search and simply processes the methods in order.

Parameters:

type - param

name - of class

parms - classes

Returns:

Method object
