    JMenuBar

      protected class JMenuBar.AccessibleJMenuBar

  This class implements accessibility support for the `JMenuBar` class. It provides an implementation of the Java Accessibility API appropriate to menu bar user-interface elements.

  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`.

  - ### Method Detail

    - #### getAccessibleStateSet

          public AccessibleStateSet getAccessibleStateSet()

      Get the accessible state set of this object.
      Overrides:
        `getAccessibleStateSet` in class `JComponent.AccessibleJComponent`
      Returns:
        an instance of AccessibleState containing the current state of the object
      See Also:
        `AccessibleState`

    - #### getAccessibleRole

          public AccessibleRole getAccessibleRole()

      Get the role of this object.
      Overrides:
        `getAccessibleRole` in class `JComponent.AccessibleJComponent`
      Returns:
        an instance of AccessibleRole describing the role of the object
      See Also:
        `AccessibleRole`

    - #### getAccessibleSelection

          public AccessibleSelection getAccessibleSelection()

      Get the AccessibleSelection associated with this object. In the implementation of the Java Accessibility API for this class, return this object, which is responsible for implementing the AccessibleSelection interface on behalf of itself.
      Overrides:
        `getAccessibleSelection` in class `AccessibleContext`
      Returns:
        this object
      See Also:
        `AccessibleSelection`

    - #### getAccessibleSelectionCount

          public int getAccessibleSelectionCount()

      Returns 1 if a menu is currently selected in this menu bar.
      Specified by:
        `getAccessibleSelectionCount` in interface `AccessibleSelection`
      Returns:
        1 if a menu is currently selected, else 0

    - #### getAccessibleSelection

          public Accessible getAccessibleSelection(int i)

      Returns the currently selected menu if one is selected, otherwise null.
      Specified by:
        `getAccessibleSelection` in interface `AccessibleSelection`
      Parameters:
        `i` - the zero-based index of selected children
      Returns:
        the i-th selected child
      See Also:
        `AccessibleSelection.getAccessibleSelectionCount()`

    - #### isAccessibleChildSelected

          public boolean isAccessibleChildSelected(int i)

      Returns true if the current child of this object is selected.
      Specified by:
        `isAccessibleChildSelected` in interface `AccessibleSelection`
      Parameters:
        `i` - the zero-based index of the child in this Accessible object.
      Returns:
        true if the current child of this object is selected; else false.
      See Also:
        `AccessibleContext.getAccessibleChild(int)`

    - #### addAccessibleSelection

          public void addAccessibleSelection(int i)

      Selects the nth menu in the menu bar, forcing it to pop up. If another menu is popped up, this will force it to close. If the nth menu is already selected, this method has no effect.
      Specified by:
        `addAccessibleSelection` in interface `AccessibleSelection`
      Parameters:
        `i` - the zero-based index of selectable items
      See Also:
        `getAccessibleStateSet()`

    - #### removeAccessibleSelection

          public void removeAccessibleSelection(int i)

      Removes the nth selected item in the object from the object's selection. If the nth item isn't currently selected, this method has no effect. Otherwise, it closes the popup menu.
      Specified by:
        `removeAccessibleSelection` in interface `AccessibleSelection`
      Parameters:
        `i` - the zero-based index of selectable items
      See Also:
        `AccessibleContext.getAccessibleChild(int)`

    - #### clearAccessibleSelection

          public void clearAccessibleSelection()

      Clears the selection in the object, so that nothing in the object is selected. This will close any open menu.
      Specified by:
        `clearAccessibleSelection` in interface `AccessibleSelection`

    - #### selectAllAccessibleSelection

          public void selectAllAccessibleSelection()

      Normally causes every selected item in the object to be selected if the object supports multiple selections. This method makes no sense in a menu bar, and so does nothing.
      Specified by:
        `selectAllAccessibleSelection` in interface `AccessibleSelection`
