31 * The AccessibleObject class is the base class for Field, Method and
32 * Constructor objects. It provides the ability to flag a reflected
33 * object as suppressing default Java language access control checks
34 * when it is used. The access checks--for public, default (package)
35 * access, protected, and private members--are performed when Fields,
36 * Methods or Constructors are used to set or get fields, to invoke
37 * methods, or to create and initialize new instances of classes,
40 * <p>Setting the {@code accessible} flag in a reflected object
41 * permits sophisticated applications with sufficient privilege, such
42 * as Java Object Serialization or other persistence mechanisms, to
43 * manipulate objects in a manner that would normally be prohibited.
45 * <p>By default, a reflected object is <em>not</em> accessible.
