      public abstract class JComponent.AccessibleJComponent
      extends Container.AccessibleAWTContainer
      implements AccessibleExtendedComponent

  Inner class of JComponent used to provide default support for accessibility. This class is not meant to be used directly by application developers, but is instead meant only to be subclassed by component developers.

  Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the `java.beans` package. Please see `XMLEncoder`.

- - ### Field Detail

    - #### accessibleFocusHandler

          @Deprecated
          protected FocusListener accessibleFocusHandler

      Deprecated.
      This field duplicates the function of the accessibleAWTFocusHandler field in java.awt.Component.AccessibleAWTComponent, so it has been deprecated.

  - ### Constructor Detail

    - #### AccessibleJComponent

          protected AccessibleJComponent()

      Though the class is abstract, this should be called by all sub-classes.

  - ### Method Detail

    - #### addPropertyChangeListener

          public void addPropertyChangeListener(PropertyChangeListener listener)

      Adds a PropertyChangeListener to the listener list.
      Overrides:
        `addPropertyChangeListener` in class `Container.AccessibleAWTContainer`
      Parameters:
        `listener` - the PropertyChangeListener to be added
      See Also:
        `AccessibleContext.ACCESSIBLE_NAME_PROPERTY`, `AccessibleContext.ACCESSIBLE_DESCRIPTION_PROPERTY`, `AccessibleContext.ACCESSIBLE_STATE_PROPERTY`, `AccessibleContext.ACCESSIBLE_VALUE_PROPERTY`, `AccessibleContext.ACCESSIBLE_SELECTION_PROPERTY`, `AccessibleContext.ACCESSIBLE_TEXT_PROPERTY`, `AccessibleContext.ACCESSIBLE_VISIBLE_DATA_PROPERTY`

    - #### removePropertyChangeListener

          public void removePropertyChangeListener(PropertyChangeListener listener)

      Removes a PropertyChangeListener from the listener list. This removes a PropertyChangeListener that was registered for all properties.
      Overrides:
        `removePropertyChangeListener` in class `Container.AccessibleAWTContainer`
      Parameters:
        `listener` - the PropertyChangeListener to be removed

    - #### getBorderTitle

          protected String getBorderTitle(Border b)

      Recursively search through the border hierarchy (if it exists) for a TitledBorder with a non-null title. This does a depth first search on first the inside borders then the outside borders. The assumption is that titles make really pretty inside borders but not very pretty outside borders in compound border situations. It's rather arbitrary, but hopefully decent UI programmers will not create multiple titled borders for the same component.

    - #### getAccessibleName

          public String getAccessibleName()

      Gets the accessible name of this object. This should almost never return java.awt.Component.getName(), as that generally isn't a localized name, and doesn't have meaning for the user. If the object is fundamentally a text object (such as a menu item), the accessible name should be the text of the object (for example, "save"). If the object has a tooltip, the tooltip text may also be an appropriate String to return.
      Overrides:
        `getAccessibleName` in class `Component.AccessibleAWTComponent`
      Returns:
        the localized name of the object -- can be null if this object does not have a name
      See Also:
        `AccessibleContext.setAccessibleName(java.lang.String)`

    - #### getAccessibleDescription

          public String getAccessibleDescription()

      Gets the accessible description of this object. This should be a concise, localized description of what this object is - what is its meaning to the user. If the object has a tooltip, the tooltip text may be an appropriate string to return, assuming it contains a concise description of the object (instead of just the name of the object - for example a "Save" icon on a toolbar that had "save" as the tooltip text shouldn't return the tooltip text as the description, but something like "Saves the current text document" instead).
      Overrides:
        `getAccessibleDescription` in class `Component.AccessibleAWTComponent`
      Returns:
        the localized description of the object -- can be null if this object does not have a description
      See Also:
        `AccessibleContext.setAccessibleDescription(java.lang.String)`

    - #### getAccessibleRole

          public AccessibleRole getAccessibleRole()

      Gets the role of this object.
      Overrides:
        `getAccessibleRole` in class `Component.AccessibleAWTComponent`
      Returns:
        an instance of AccessibleRole describing the role of the object
      See Also:
        `AccessibleRole`

    - #### getAccessibleStateSet

          public AccessibleStateSet getAccessibleStateSet()

      Gets the state of this object.
      Overrides:
        `getAccessibleStateSet` in class `Component.AccessibleAWTComponent`
      Returns:
        an instance of AccessibleStateSet containing the current state set of the object
      See Also:
        `AccessibleState`

    - #### getAccessibleChildrenCount

          public int getAccessibleChildrenCount()

      Returns the number of accessible children in the object. If all of the children of this object implement Accessible, than this method should return the number of children of this object.
      Overrides:
        `getAccessibleChildrenCount` in class `Container.AccessibleAWTContainer`
      Returns:
        the number of accessible children in the object.

    - #### getAccessibleChild

          public Accessible getAccessibleChild(int i)

      Returns the nth Accessible child of the object.
      Overrides:
        `getAccessibleChild` in class `Container.AccessibleAWTContainer`
      Parameters:
        `i` - zero-based index of child
      Returns:
        the nth Accessible child of the object
      See Also:
        `AccessibleContext.getAccessibleChildrenCount()`

    - #### getToolTipText

          public String getToolTipText()

      Returns the tool tip text
      Specified by:
        `getToolTipText` in interface `AccessibleExtendedComponent`
      Returns:
        the tool tip text, if supported, of the object; otherwise, null
      Since:
        1.4

    - #### getTitledBorderText

          public String getTitledBorderText()

      Returns the titled border text
      Specified by:
        `getTitledBorderText` in interface `AccessibleExtendedComponent`
      Returns:
        the titled border text, if supported, of the object; otherwise, null
      Since:
        1.4

    - #### getAccessibleKeyBinding

          public AccessibleKeyBinding getAccessibleKeyBinding()

      Returns key bindings associated with this object
      Specified by:
        `getAccessibleKeyBinding` in interface `AccessibleExtendedComponent`
      Returns:
        the key bindings, if supported, of the object; otherwise, null
      Since:
        1.4
      See Also:
        `AccessibleKeyBinding`
