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 oneAccessibleAction
in them.- Specified by:
getAccessibleActionCount
in interfaceAccessibleAction
- 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 interfaceAccessibleAction
- Parameters:
i
- zero-based index of actions- Returns:
true
if the action was performed; otherwisefalse
- See Also:
-
getAccessibleActionDescription
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 interfaceAccessibleAction
- Parameters:
i
- zero-based index of the actions- Returns:
- a string description of the action
- See Also:
-
getAccessibleActionObject
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:
-
getAccessibleActionAnchor
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 aString
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:
-
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
