Class Overview

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.

Public Methods

public T getAnnotation (Class<T> annotationType)

Added in API level 1

Returns, for this element, the annotation with the specified type, or null if no annotation with the specified type is present (including inherited annotations).

Parameters
annotationType the type of the annotation to search for
Returns
  • the annotation with the specified type or null

public Annotation[] getAnnotations ()

Added in API level 1

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
  • an array of all annotations for this element

public Annotation[] getDeclaredAnnotations ()

Added in API level 1

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.

Returns
  • an array of annotations declared for this element

public boolean isAccessible ()

Added in API level 1

Returns true if this object is accessible without access checks.

public boolean isAnnotationPresent (Class<? extends Annotation> annotationType)

Added in API level 1

Indicates whether or not this element has an annotation with the specified annotation type (including inherited annotations).

Parameters
annotationType the type of the annotation to search for
Returns
  • true if the annotation exists, false otherwise

public void setAccessible (boolean flag)

Added in API level 1

Attempts to set the accessible flag. Setting this to true prevents IllegalAccessExceptions.

public static void setAccessible (AccessibleObject[] objects, boolean flag)

Added in API level 1

Attempts to set the accessible flag for all objects in objects. Setting this to true prevents IllegalAccessExceptions.
