Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public Methods

public static void ensureMemberAccess (Class currentClass, Class memberClass, Object target, int modifiers)

Throws

IllegalAccessException

public static Field[] filterFields (Class containingClass, Field[] fields)

public static Method[] filterMethods (Class containingClass, Method[] methods)

public static Class getCallerClass (int realFramesToSkip)

Returns the class of the method realFramesToSkip frames up the stack (zero-based), ignoring frames associated with java.lang.reflect.Method.invoke() and its implementation. The first frame is that associated with this method, so getCallerClass(0) returns the Class object for sun.reflect.Reflection. Frames associated with java.lang.reflect.Method.invoke() and its implementation are completely ignored and do not count toward the number of "real" frames skipped.

public static boolean quickCheckMemberAccess (Class memberClass, int modifiers)

A quick "fast-path" check to try to avoid getCallerClass() calls.
