- Method Detail
  - isValid
    public abstract boolean isValid()
    
    Since the document a link is associated with may have changed, this method returns whether or not this Link is still valid (with respect to the document it references).
    
    Returns:
    a flag indicating whether this link is still valid with respect to the AccessibleHypertext it belongs to
  - getAccessibleActionCount
    public abstract int getAccessibleActionCount()
    
    Returns the number of accessible actions available in this Link If there are more than one, the first one is NOT considered the "default" action of this LINK object (e.g. in an HTML imagemap). In general, links will have only one AccessibleAction in them.
    
    Specified by:
    
    getAccessibleActionCount in interface AccessibleAction
    
    Returns:
    the zero-based number of Actions in this object
  - doAccessibleAction
    public abstract boolean doAccessibleAction(int i)
    
    Performs the specified Action on the object
    
    Specified by:
    
    doAccessibleAction in interface AccessibleAction
    
    Parameters:
    i - zero-based index of actions
    
    Returns:
    true if the action was performed; otherwise false.
    See Also:
    getAccessibleActionCount()
  - getAccessibleActionDescription
    public abstract String getAccessibleActionDescription(int i)
    
    Returns a String description of this particular link action. This should be a text string associated with anchoring text, this should be the anchor text. E.g. from HTML: <a HREF="http://www.sun.com/access">Accessibility</a> this method would return "Accessibility". Similarly, from this HTML: <a HREF="#top"><img src="https://www.gaudry.be/nl/java-api/top-hat.gif" alt="top hat"></a> this method would return "top hat"
    
    Specified by:
    
    getAccessibleActionDescription in interface AccessibleAction
    
    Parameters:
    i - zero-based index of the actions
    
    Returns:
    a String description of the action
    See Also:
    getAccessibleActionCount()
  - getAccessibleActionObject
    public abstract Object getAccessibleActionObject(int i)

    Parameters:
    i - zero-based index of the actions
    
    Returns:

    getAccessibleActionCount()
  - getAccessibleActionAnchor
    public abstract Object getAccessibleActionAnchor(int i)
    
    Returns an object that represents the link anchor, as appropriate for that link.
