ReflectionFactory

extends Object

java.lang.Object
↳	sun.reflect.ReflectionFactory

Class Overview

The master factory for all reflective objects, both those in java.lang.reflect (Fields, Methods, Constructors) as well as their delegates (FieldAccessors, MethodAccessors, ConstructorAccessors).

The methods in this class are extremely unsafe and can cause subversion of both the language and the verifier. For this reason, they are all instance methods, and access to the constructor of this factory is guarded by a security check, in similar style to Unsafe.

Summary

Nested Classes
class	ReflectionFactory.GetReflectionFactoryAction	A convenience class for acquiring the capability to instantiate reflective objects.

Public Methods
Constructor	copyConstructor(Constructor arg) Makes a copy of the passed constructor.
Field	copyField(Field arg) Makes a copy of the passed field.
Method	copyMethod(Method arg) Makes a copy of the passed method.
ConstructorAccessor	getConstructorAccessor(Constructor c) Gets the ConstructorAccessor object for a java.lang.reflect.Constructor
MethodAccessor	getMethodAccessor(Method m) Gets the MethodAccessor object for a java.lang.reflect.Method
static ReflectionFactory	getReflectionFactory() Provides the caller with the capability to instantiate reflective objects.
Constructor	newConstructor(Class declaringClass, Class[] parameterTypes, Class[] checkedExceptions, int modifiers, int slot, String signature, byte[] annotations, byte[] parameterAnnotations) Creates a new java.lang.reflect.Constructor.
ConstructorAccessor	newConstructorAccessor(Constructor c)
Constructor	newConstructorForSerialization(Class classToInstantiate, Constructor constructorToCall)
Field	newField(Class declaringClass, String name, Class type, int modifiers, int slot, String signature, byte[] annotations) Creates a new java.lang.reflect.Field.
FieldAccessor	newFieldAccessor(Field field, boolean override) Note: this routine can cause the declaring class for the field be initialized and therefore must not be called until the first get/set of this field.
Method	newMethod(Class declaringClass, String name, Class[] parameterTypes, Class returnType, Class[] checkedExceptions, int modifiers, int slot, String signature, byte[] annotations, byte[] parameterAnnotations, byte[] annotationDefault) Creates a new java.lang.reflect.Method.

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 Constructor copyConstructor (Constructor arg)

Makes a copy of the passed constructor. The returned constructor is a "child" of the passed one; see the comments in Constructor.java for details.

public Field copyField (Field arg)

Makes a copy of the passed field. The returned field is a "child" of the passed one; see the comments in Field.java for details.

public Method copyMethod (Method arg)

Makes a copy of the passed method. The returned method is a "child" of the passed one; see the comments in Method.java for details.

public ConstructorAccessor getConstructorAccessor (Constructor c)

Gets the ConstructorAccessor object for a java.lang.reflect.Constructor

public MethodAccessor getMethodAccessor (Method m)

Gets the MethodAccessor object for a java.lang.reflect.Method

public static ReflectionFactory getReflectionFactory ()

Provides the caller with the capability to instantiate reflective objects.

First, if there is a security manager, its checkPermission method is called with a RuntimePermission with target "reflectionFactoryAccess". This may result in a security exception.

The returned ReflectionFactory object should be carefully guarded by the caller, since it can be used to read and write private data and invoke private methods, as well as to load unverified bytecodes. It must never be passed to untrusted code.

Throws

SecurityException	if a security manager exists and its `checkPermission` method doesn't allow access to the RuntimePermission "reflectionFactoryAccess".

public Constructor newConstructor (Class declaringClass, Class[] parameterTypes, Class[] checkedExceptions, int modifiers, int slot, String signature, byte[] annotations, byte[] parameterAnnotations)

Creates a new java.lang.reflect.Constructor. Access checks as per java.lang.reflect.AccessibleObject are not overridden.

public ConstructorAccessor newConstructorAccessor (Constructor c)

public Constructor newConstructorForSerialization (Class classToInstantiate, Constructor constructorToCall)

public Field newField (Class declaringClass, String name, Class type, int modifiers, int slot, String signature, byte[] annotations)

Creates a new java.lang.reflect.Field. Access checks as per java.lang.reflect.AccessibleObject are not overridden.

public FieldAccessor newFieldAccessor (Field field, boolean override)

Note: this routine can cause the declaring class for the field be initialized and therefore must not be called until the first get/set of this field.

Parameters

field	the field
override	true if caller has overridden aaccessibility

public Method newMethod (Class declaringClass, String name, Class[] parameterTypes, Class returnType, Class[] checkedExceptions, int modifiers, int slot, String signature, byte[] annotations, byte[] parameterAnnotations, byte[] annotationDefault)

Creates a new java.lang.reflect.Method. Access checks as per java.lang.reflect.AccessibleObject are not overridden.

public MethodAccessor newMethodAccessor (Method method)

public void setConstructorAccessor (Constructor c, ConstructorAccessor accessor)

Sets the ConstructorAccessor object for a java.lang.reflect.Constructor

public void setLangReflectAccess (LangReflectAccess access)

Called only by java.lang.reflect.Modifier's static initializer

public void setMethodAccessor (Method m, MethodAccessor accessor)

Sets the MethodAccessor object for a java.lang.reflect.Method
