pack-priv Class NarcissusReflectionDriver

extends ReflectionDriver
Class Inheritance
Imports
java.lang.reflect.AccessibleObject, .Constructor, .Field, .Method
Narcissus reflection driver (uses the Narcissus library, if it is available, which allows access to non-public fields and methods, circumventing encapsulation and visibility controls via JNI).
