Create a new Method object from scratch. This Method object is 'fake' and will not be "invokable". ReflectionInterceptor will be responsible to make sure user code calling 'invoke' on this object will be intercepted and handled appropriately.

copyMethod

public static java.lang.reflect.Method copyMethod(java.lang.reflect.Method method)

Creates a copy of a method object that is equivalent to the original.

copyField

public static java.lang.reflect.Field copyField(java.lang.reflect.Field field)

copyConstructor

public static java.lang.reflect.Constructor<?> copyConstructor(java.lang.reflect.Constructor<?> c)

setMethodModifiers
