Method Detail

lookup

sun.misc.Unsafe lookup()

unlockNative

void unlockNative(Method method)

Fixes a problem with calling a method that contains a native keyword via the Java Reflection API

Parameters:

method - The method to perform on

defineClass

Class<?> defineClass(String name,
                     byte[] data)
              throws NoSuchMethodException,
                     InvocationTargetException,
                     IllegalAccessException

Allows you to initialize a class with the correct name and automatically load it into runtime in SystemClassLoader loader

Parameters:

name - Correct class name

data - Correct class byte data

Returns:

Class that successfully loaded

Throws:

NoSuchMethodException - This error cannot be thrown, but it will have to be handled (because I am pussy)

InvocationTargetException - If the data or name is incorrect (check docs before using this method)

IllegalAccessException - This error cannot be thrown, but it will have to be handled (because I am pussy)

isClassPresents

boolean isClassPresents(String className,
                        ClassLoader loader)

Checks whether the class is loaded in the specified class loader

Parameters:

className - Class name to check

loader - Exact class loader

Returns:

If loaded - true, otherwise - false

redefineClassLoader

void redefineClassLoader(Class<?> clazz,
                         ClassLoader loader)

Allows you to change the class loader of the specified class to any other loader

Parameters:

clazz - Exact class

loader - Exact class loader

godInvoke

Object godInvoke(Method method,
                 Object o,
                 Object... args)
          throws InvocationTargetException,
                 IllegalAccessException

Allows you to call invoke on an instance of a method with all privileges

Parameters:

method - The method to be executed

o - The object the underlying method is invoked from

args - The arguments used for the method call

Returns:

The result of dispatching the method represented by this object on obj with parameters args
