- ## Constructor Details

  - ### AccessibleJListChild

    public AccessibleJListChild(JList<E> parent, int indexInParent)
    Constructs an `AccessibleJListChild`.

      `indexInParent` - the index in the parent

- ## Method Details

  - ### getAccessibleContext

    public AccessibleContext getAccessibleContext()
    Get the AccessibleContext for this object. In the implementation of the Java Accessibility API for this class, returns this object, which is its own AccessibleContext.
    Specified by:
      `getAccessibleContext` in interface `Accessible`
    Returns:
      this object

  - ### setAccessibleName

    public void setAccessibleName(String s)
    Description copied from class: `AccessibleContext`
    Sets the localized accessible name of this object. Changing the name will cause a `PropertyChangeEvent` to be fired for the `ACCESSIBLE_NAME_PROPERTY` property.
    Overrides:
      `setAccessibleName` in class `AccessibleContext`
    Parameters:
      `s` - the new localized name of the object
    See Also:
      - `AccessibleContext.getAccessibleName()`
      - `AccessibleContext.addPropertyChangeListener(java.beans.PropertyChangeListener)`

  - ### setAccessibleDescription

    public void setAccessibleDescription(String s)
    Description copied from class: `AccessibleContext`
    Sets the accessible description of this object. Changing the name will cause a `PropertyChangeEvent` to be fired for the `ACCESSIBLE_DESCRIPTION_PROPERTY` property.
    Overrides:
      `setAccessibleDescription` in class `AccessibleContext`
    Parameters:
      `s` - the new localized description of the object
    See Also:
      - `AccessibleContext.setAccessibleName(java.lang.String)`
      - `AccessibleContext.addPropertyChangeListener(java.beans.PropertyChangeListener)`

  - ### getAccessibleRole

    public AccessibleRole getAccessibleRole()
    Description copied from class: `AccessibleContext`
    Gets the role of this object. The role of the object is the generic purpose or use of the class of this object. For example, the role of a push button is `AccessibleRole.PUSH_BUTTON`. The roles in `AccessibleRole` are provided so component developers can pick from a set of predefined roles. This enables assistive technologies to provide a consistent interface to various tweaked subclasses of components (e.g., use `AccessibleRole.PUSH_BUTTON` for all components that act like a push button) as well as distinguish between subclasses that behave differently (e.g., `AccessibleRole.CHECK_BOX` for check boxes and `AccessibleRole.RADIO_BUTTON` for radio buttons).

    Note that the `AccessibleRole` class is also extensible, so custom component developers can define their own `AccessibleRole`'s if the set of predefined roles is inadequate.

    Specified by:
      `getAccessibleRole` in class `AccessibleContext`
    Returns:
      an instance of `AccessibleRole` describing the role of the object
    See Also:
      - `AccessibleRole`

    Specified by:
      `getAccessibleStateSet` in class `AccessibleContext`
    Returns:
      an instance of `AccessibleStateSet` containing the current state set of the object
    See Also:
