## Interface AccessibleExtendedText

- All Known Implementing Classes:
    JEditorPane.AccessibleJEditorPane, JEditorPane.AccessibleJEditorPaneHTML, JEditorPane.JEditorPaneAccessibleHypertextSupport, JPasswordField.AccessibleJPasswordField, JTextArea.AccessibleJTextArea, JTextComponent.AccessibleJTextComponent, JTextField.AccessibleJTextField

      public interface AccessibleExtendedText

  The AccessibleExtendedText interface contains additional methods not provided by the AccessibleText interface Applications can determine if an object supports the AccessibleExtendedText interface by first obtaining its AccessibleContext (see `Accessible`) and then calling the `AccessibleContext.getAccessibleText()` method of AccessibleContext. If the return value is an instance of AccessibleExtendedText, the object supports this interface.

  Since:
    1.5
