Interface AccessibleHypertext

All Superinterfaces:: AccessibleText

All Known Implementing Classes:: JEditorPane.JEditorPaneAccessibleHypertextSupport

public interface AccessibleHypertext extends AccessibleText

The AccessibleHypertext class is the base class for all classes that present hypertext information on the display. This class provides the standard mechanism for an assistive technology to access that text via its content, attributes, and spatial location. It also provides standard mechanisms for manipulating hyperlinks. Applications can determine if an object supports the AccessibleHypertext interface by first obtaining its AccessibleContext (see Accessible) and then calling the AccessibleContext.getAccessibleText() method of AccessibleContext. If the return value is a class which extends AccessibleHypertext, then that object supports AccessibleHypertext.
