[g-a-devel]questions on nsIAccessibleHyperLink

[Gilbert Fang <gilbert fang sun com>]

Hi, Bill and John,
   I am Gilbert from Sun browser accessible group(ATF). Now I am
implementing the nsIAccessibleHyperlink. There are some questions on
that interface:

So unfortunately, in jdk 1.3's document, the only class which implements
AccessibleHyperlink is
JEditorPane.JEditorPaneAccessibleHypertextSupport.HTMLLink
(http://java.sun.com/j2se/1.3/docs/api/javax/swing/JEditorPane.JEditorPaneAccessibleHypertextSupport.HTMLLink.html)
And this class actually does not support any multi-anchor hyperlink.
See its codes:
	    public int getAccessibleActionCount() {
		return 1;
	    }
and
	    public Object getAccessibleActionObject(int i) {
		if (i == 0 && isValid() == true) {
		    AttributeSet as = element.getAttributes();
		    AttributeSet anchor =
			(AttributeSet) as.getAttribute(HTML.Tag.A);
		    String href = (anchor != null) ?
			(String) anchor.getAttribute(HTML.Attribute.HREF) : null;
		    if (href != null) {
			URL u;
			try {
			    u = new URL(JEditorPane.this.getPage(), href);
			} catch (MalformedURLException m) {
			    u = null;
			}
			return u;
		    }
		}
		return null;  // link invalid or i != 0
	    }
It always return 1 for count and only support the index 0.
So, if we have such kind of hypertext, how  do we construct anchors for it?
<a> first part <img src=second.img> third part</a>
Now, in mozilla, it will be exposed as a link accNode(ROLE_LINK) with three
accChildren, accNodeA (ROLE_TEXT) for " first part", 
accNodeB(ROLE_GRAPHIC) for
the "second.img" , accNodeC(ROLE_TEXT) for "third part".
In my opinion, it should be a hyperlink with *3* anchors with the same
action(url). Although it actually has just one tag <a href=>, it will be 
showed as three part in user interface in *3* area.
Hi, Bill and Aron and John, could u tell what your suggestions are ?
