AccessibleObject
is the superclass of all member reflection classes
(Field, Constructor, Method). AccessibleObject provides the ability to toggle
a flag controlling access checks for these objects. By default, accessing a
member (for example, setting a field or invoking a method) checks the
validity of the access (for example, invoking a private method from outside
the defining class is prohibited) and throws IllegalAccessException if the
operation is not permitted. If the accessible flag is set to true, these
checks are omitted. This allows privileged code, such as Java object
serialization, object inspectors, and debuggers to have complete access to
objects.

Constructs a new AccessibleObject

instances can only be constructed by the virtual
machine.
Returns, for this element, the annotation with the specified type, or

if no annotation with the specified type is present
(including inherited annotations).

null
Returns, for this element, an array containing all annotations (including inherited annotations). If there are no annotations present, this method returns a zero length array.
Returns, for this element, all annotations that are explicitly declared (not inherited). If there are no declared annotations present, this method returns a zero length array.
Indicates whether this object is accessible without access checks being performed. Returns the accessible flag.
true
if this object is accessible without access
checks, false
otherwise
Indicates whether or not this element has an annotation with the specified annotation type (including inherited annotations).
