### JTableHeader.AccessibleJTableHeader.AccessibleJTableHeaderEntry

    public JTableHeader.AccessibleJTableHeader.AccessibleJTableHeaderEntry(int c,
                                                                           JTableHeader p,
                                                                           JTable t)

  Constructs an AccessiblJTableHeaaderEntry

Method Detail

### getAccessibleContext

    public AccessibleContext getAccessibleContext()

  Get the AccessibleContext associated with this object. In the implementation of the Java Accessibility API for this class, returns this object, which serves as its own AccessibleContext.

  Specified by:
    `getAccessibleContext` in interface `Accessible`
  Returns:
    this object

### getAccessibleName

    public String getAccessibleName()

  Description copied from class: `AccessibleContext`
  Gets the accessibleName property of this object. The accessibleName property of an object is a localized String that designates the purpose of the object. For example, the accessibleName property of a label or button might be the text of the label or button itself. In the case of an object that doesn't display its name, the accessibleName should still be set. For example, in the case of a text field used to enter the name of a city, the accessibleName for the en_US locale could be 'city.'

  Overrides:
    `getAccessibleName` in class `AccessibleContext`
  Returns:
    the localized name of the object; null if this object does not have a name
  See Also:
    `AccessibleContext.setAccessibleName(java.lang.String)`

### 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)`

### getAccessibleDescription

    public String getAccessibleDescription()

  Description copied from class: `AccessibleContext`
  Gets the accessibleDescription property of this object. The accessibleDescription property of this object is a short localized phrase describing the purpose of the object. For example, in the case of a 'Cancel' button, the accessibleDescription could be 'Ignore changes and close dialog box.'

  Overrides:
    `getAccessibleDescription` in class `AccessibleContext`
  Returns:
    the localized description of the object; null if this object does not have a description
  See Also:
    `AccessibleContext.setAccessibleDescription(java.lang.String)`

### 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 sublasses 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`

### getAccessibleStateSet

    public AccessibleStateSet getAccessibleStateSet()

  Description copied from class: `AccessibleContext`
  Gets the state set of this object. The AccessibleStateSet of an object is composed of a set of unique AccessibleStates. A change in the AccessibleStateSet of an object will cause a PropertyChangeEvent to be fired for the ACCESSIBLE_STATE_PROPERTY property.

  Specified by:
    `getAccessibleStateSet` in class `AccessibleContext`
  Returns:
    an instance of AccessibleStateSet containing the current state set of the object
  See Also:
    `AccessibleStateSet`, `AccessibleState`, `AccessibleContext.addPropertyChangeListener(java.beans.PropertyChangeListener)`

    `getAccessibleChild` in class `AccessibleContext`
  Parameters:
    `i` - zero-based index of child
