public abstract class AccessibleHyperlink
extends Object
implements AccessibleAction

Encapsulation of a link, or set of links (e.g. client side imagemap) in a Hypertext document

`AccessibleHyperlink()`

Method Summary
`abstract boolean` | `doAccessibleAction(int i)` Performs the specified Action on the object
`abstract Object` | `getAccessibleActionAnchor(int i)` Returns an object that represents the link anchor, as appropriate for that link.
`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.
`abstract String` | `getAccessibleActionDescription(int i)` Returns a String description of this particular link action.
`abstract Object` | `getAccessibleActionObject(int i)` Returns an object that represents the link action, as appropriate for that link.
`abstract int` | `getEndIndex()` Gets the index with the hypertext document at which this link ends
`abstract int` | `getStartIndex()` Gets the index with the hypertext document at which this link begins
`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).

Constructor Detail

### AccessibleHyperlink

    public AccessibleHyperlink()

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="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)

  Returns an object that represents the link action, as appropriate for that link. E.g. from HTML: <a HREF="http://www.sun.com/access">Accessibility</a> this method would return a java.net.URL("http://www.sun.com/access.html");
  Parameters:
    `i` - zero-based index of the actions
  Returns:
    an Object representing the hypertext link itself
  See Also:
    `getAccessibleActionCount()`

### getAccessibleActionAnchor

    public abstract Object getAccessibleActionAnchor(int i)

  Returns an object that represents the link anchor, as appropriate for that link. E.g. from HTML: <a href="http://www.sun.com/access">Accessibility</a> this method would return a String containing the text: "Accessibility". Similarly, from this HTML: <a HREF="#top"><img src="top-hat.gif" alt="top hat"></a> this might return the object ImageIcon("top-hat.gif", "top hat");
  Parameters:
    `i` - zero-based index of the actions
  Returns:
    an Object representing the hypertext anchor
  See Also:
    `getAccessibleActionCount()`

### getStartIndex

    public abstract int getStartIndex()

  Gets the index with the hypertext document at which this link begins
  Returns:
    index of start of link

### getEndIndex

    public abstract int getEndIndex()

  Gets the index with the hypertext document at which this link ends
  Returns:
    index of end of link
